This thread is for everyone to post their wheel and tire info along with photos of their cars.

Information that is needed...

Wheel diameter.
Wheel width.
Wheel back spacing.

Example...15x7 with 4" of b.s.

Tire size.
Example...255/60/15

The make of the wheel and tire.
Example...Rally Wheel with BFGoodrich Radial T/A tires.

Added info like springs, spring spacers, airbags, etc...being used is also helpful so everyone one will know how you achieved your cars stance. Also any info like if the wheel lip was trimmed, wheel spacers were needed, wheel well altered, etc...to get tires to fit.

Comments are welcome of cars posted but may be deleted overtime to keep this thread simple and condensed.

15X8 aftermarket Rally wheels 5 in. BS all the way around
B.F. Goodrich TA Radials 255/60 in front 275/60 in rear
Small block springs of unknown origin in the front airbags in the rear for maintaining "attitude" when the trunk is fully loaded for road trips. I get a slight rub when I hit a severe "whoop-te-do" in the front. Tires are hitting the inner fender well not lip. I would have no rubbing in the rear without the airbags. Probably none in the front if I had proper big block springs like I should. Side note: the stock 15X7 trim rings fit for a semi-sleeper look.

Just saw this post. Great idea Bill.

17x 9-1/2 with 5-1/2 BS on rear. Coddington's
17x 8 with 4-1/2 BS on front. Coddington's

Nitto rubber.
245-45-17
255-50-17

Stock big block springs and suspension. No rubbing issues at all after I trimmed the rear wheel wells. I think that with another 1/4" BS on the rims you would not have to trim the wheel well. I had the rims custom cut so I could not return them and change the BS.

20x9" front, 6.5 backspacing w/ 1 inch spacer
20x10.5" rear, 7.5 backspacing w/ 1.5 inch spacer

245/35/20 front
275/35/20 rear, will go to a 295 or 305 when i need new rears

Greg Weld Racelite Wheels with Kumho Ecsta SPT fronts
Michelin Pilot Primacy rears

hotchkis 1 inch drop springs all the way around, 2 inch drop spindles

Had to trim rear wheel lips, but when i get wider rear tires I will get the rear spacers machined down a bit, have about a inch and a half of room on the inside, half an inch at the closest point on the outside.

Thinking about dropping the saggy old springs in the back...

One day I will get the OPG 3" drop rears and cut a half coil or so on my fronts.

I like the way you are going... a smaller diameter tire will lower the front end slightly, and improve brake performance up front. With a 14" rim you can still put decent rubber around it to look like a big tire. The problem is that I don't know if it will fit over the calipers; I can't think of any GM car that had disc brakes and 14" wheels.
I don't think there would be any problem if it had drum brakes, but with discs...I dunno.
I like the "anti-social" old-school thinking here. If all the kids are wearing their pants on the ground, then I'm proud to have mine belted below my ribs. Imagine a Monte with 14" wheels all around, and BIG rubber tires! 245/60 14 looks as about as big as they get

...But those are about the same diameter as the 245/15
Of course there are much smaller sizes available in 14" for the front axle...

Hey guys, does anyone know if a 275-50/15 will fit in the rear?
I see the section width is identical to the 275-60, but it has a bit wider tread and is shorter in height.

I found a good deal locally on some Hoosier quick time tires in this size....Maybe I should be asking you if the Hoosier is any good?

The shovell is a little different, I'd think.
I've seen that most everyone here runs a 275/60 drag tire, but I like the shorter height of the 50 series.

The Hoosier quick time is a bias-ply tire. Does that make it bad?
I also see that tire sizes vary from manufacturer:

The MT ET street 275/60------------Hoosier quick time 275/50
Dia...section....tread-----------------Dia.....section....tread
28.0....11.0.......9.5-----------------26.1....11.6.......10.0

The 50 series Hoosier is 2" shorter, but is also 1/2" wider in both section and tread width.
It's an expensive gamble. I'd hate to buy them and find they won't fit...or work well for that matter.

I'm another one on this exact combo (275/50/15, 15x8x4-1/2 BS). Lips are not trimmed though, not hit yet... looks like there could be a collision course it the rear end travels to an extreme though. The tires are BF Goodrich T/A Radials.

I just picked them up used this weekend, nice guy, let me test fit them right there. There is a mile of room to the inside to the frame, but the way the exhaust is run, only about 1/4" of clearance to the pipe on the inside.

Mazzi #725 rims
20x8.5
Not sure on the back spacing
255/35ZR 20 tires

I dont think any mods were done to get them to fit because they were on the car when i got it, anyways the dont rub at all.

I've posted my info before but not with a pic:

BFG 255/60/15 on stock 7 inch rally wheels. Stock suspension. This may not work of your old front springs have sagged. I installed new original style Moog springs before installing these tires.

I'm using 275/60R15 BF Goodrich's on my 15x7 wheel....although it depends more on your suspension height and how much sag are in the rear springs. I use air shocks, so I can adjust the rear height.

I have about a 1/4 inch between the sidewall and the lip. I am going to trim the lip about a 1/4 inch to help with clearance.

Front: Wheel Vintiques Rallys 15X7 w/4" BS; BF Goodrich Radial T/A 255/60-15, no-logo derby caps, 3" trim rings

Rear: Wheel Vintiques Rallys 15x8 w/5" BS; BF Goodrich Radial T/A 275/60-15, no-logo derby caps, 3" trim rings

I upgraded from what was on the car when I bought it last January; (4) 245/60-15 Hercules Honcho Radials on 15x6 w/3.5" BS rally wheels originally from a '70 El Camino. A 6" rim is too narrow for that tire and really looked strange, although they obviously worked. There has been an amzaing improvement in steering and ride with the new wheels and tires. It should be even better when I finish rebuilding my front suspension and adding power steering. My speedometer is accurate again, also.

I just installed on my 1971 Monte MT 295/55-15 ET Drag Radials on 15 x 8 rally wheels with 5" backspace. The wheel well lips had been trimmed prior. There is PLENTY of room. 10.9" advertised tread width.

Do you all think I could run 275/60/15 all around with stock 15x7 rallys? I might be able to get a set of Cooper Cobras for an excellent price.

On the front too? Never seen that before, probably would look like a 4X4 with such a tall and fat tire on the front. I never tried it so I don't know if it would fit.

Assuming the backspace on your 15x7 wheels is only 4", I would be very concerned aboout interference with the quarter panel lip (although trimming the lip may get you by).

The outside of the rim on a 15X7 w/4"bs is in the same position as the outside of the rim on a 15x8 w/5" bs, however the centerline of the 10.8" wide tire on a 15x7 rim is moved outboard by at least a half inch and possibly a bit more with sidewall bulge. My 275/60s on 15x8 w/5" bs have less than one inch clearance with the untrimmed quarter panel lip.

I can't imagine the 275/60s working on the front unless you are using at least 2" spacers above stock height. My 255/60 on 15x7 rims (4" bs) actually touched something on tight turns until I installed a 1" spacer in the front coils. The 275 is a full inch taller than a 255 so that is going to eat up an addition half inch of clearance at all points around the circumference of the tire.

The tire clearance may look fine with the wheel straight, but try turning it lock to lock and what looks like abundant clearance quickly goes away (especially if you have any upward suspension travel while the wheel is tightly turned (like turning into an upward sloping driveway).

If it was my money, I would at least try or "buy" them on the condition that they will work on your paticular car.

If you like to play around with different tire and wheel sizes, you might like the Wheel/Tire Size Comparer on the following site: http://www.rimsntires.com/specs.jsp

Note that you can easily enter two different tire/wheel configurations and it will compare the second to the first. Good luck.

I decided to go with some 235/60/15 Mastercraft Avenger GT I got four new ones or like new with 9\32nds tread left. Brand new is 10.5\32nds. I had to drive a little to get them but for a $140 it was well worth it. They are a little smaller than the 245/60/15 that I really wanted to go with but at least I know they will work and they aren't what 15 years old. The thing is will these be too small? Using the calculator that MCfan provided they are actually smaller that what I have on the car now which is 215\70\15. Will it work or will it look funny? Thanks guys and girls.

My 70 Monte used to have 235/60/15 BF Goodrich tires. They did not look bad at all. Here's some photos of my car with the 235/60/15 tires:

My Monte had 245/60-15s all around when I bought it this past January. They are also "shorter" than the original G78-15s that came on the car so my speedometer registered a bit faster than I was actually going.

The tire and wheel comparer says you will be going 3% slower than your speedometer shows (assuming a stock speedometer matched to your differential ratio).

Regarding appearance, I didn't think 245/60s looked so bad except that mine were on 15x6 El Camino rally rims so the sidewalls really looked bulged. I doubt that 235/60s will look too bad on your 15x7 rims since they are only .5" shorter and .3" narrower than a 245/60.

You certainly shouldn't have any clearance issues with those tires and rims! BTW, I've learned to "like" a lot of things when the price was right!

There is lot's of good information in this section. Could it someday be put into a more usable, readable format like a spread sheet? I have no idea how to do it perhaps a link to an Excel sheet. I assume that someone would have to load the data and maintain it after parameters were established. Just thinking out loud here.

I don't think I have ever put my info in here.

I originally was running 15x7 4" bs chrome rallys up front with 235x60x15 tires. Backs were 15x8 4.5" bs chrome rallys with 255x60x15 tires.

Currently I am running 17x8 4.5" bs with 255x50x17 tires up front. Rears are 17x9 5" bs with 275x50x17 tires. Could go bigger in the back but Nitto NT 450's don't offer anything wider in that profile. IMHO I like the 50 profile/sidewall better than 45 or less. - Dave

I'm pretty sure Sam (Bones) has 15x9" wheels with 5.5" of b.s. and 275/60 tires. He said the lower shock mount is either real close or it hits I can't remember...either way the wheel you mention has a .25" less b.s. so it may fit...give him a P.M. and ask him directly in case he doesn't see your post here.

I just put Cragar black 397 rims on my Monte. Front tires are crappy douglass performance gt tires back tires are 215/75-15 and rears are 215/75-15 M/T's. I have almost no room in between the lip of the quarter inside the wheel well and the sidewall. I have air shocks already just ordered some coil spring spacers off of jegs.

Finally have something to contribute to this thread:

255/60/15 rears, 235/60/15 fronts on original rally wheels, painted black:



Just picked these up second hand...was in a hurry to just try them out on the car, so I didn't measure backspacing yet. 17" Torque Thrusts. 255's on the rear, 245's on the front.



I have a coil spring/adjustable threaded spacer set-up on the rear. Have the front set-up as well, just haven't installed it yet. Figure another inch or so lower in the front and she'll have the perfect stance!! Can't go wrong with Torque Thrusts!!

Just got some new rear tires, went from a 275/35-20 to a 295/40-20. 29.5 inches tall!
I had to trim all that I could of the fender lips and they fit with a 1.75inch adapter.
They are BFG G Force TA KDW's the old style tread pattern.
The monte also got a 3.55 gear, new axles and a posi unit.
I need to bring the rear down some now, another inch or two.
I will also be going to a 255/35-20 up front when they wear out along with some new upper control arms.

I had 275/60R15 at the back before but wanted the same all around. However, noticed with the 225s my speedometer lost some acuraccy. When I get replacements, I will go with 235/70R15 most probably as they are almost the same outer dia as the 275/60R15s.

Also found this interesting site from the Buick guys <Linky>

My 72 Monte:

245/60/15 tires on Corvette rallys (15x8 with 4 inch back spacing). They rubbed the driver's rear quarter panel when going over bumps. I put in new rear springs but still had to bend the quarter panel lip in a little to prevent it from rubbing the tire. They rub on the front going over a bump while doing a sharp turn (like entering a parking lot). The front would likely be OK if I put in new front springs.

255/60-15 on back, 225/70-15 on the front.
15x7 chrome rally on front. I think they are 4 in, 3 out.
15x8 chrome rally on back. I think they are 4 in/4 out.
I have stock center caps on it now. I do have quite a few different sets of centers, including 2 and 3 way spinners, low profile disc brake (and non-disc brake) centers, police centers, etc etc. I just like to change up the look on the rallys once in a while.

Here is a longways side shot of the car



I have a set of 15x8 1978 Corvette pace car rims I purchased a while back. I have gone through the sanding and polishing process and they turned out half decent. Not quite as nice as the chrome, but highly polished aluminum. They came with a set of BFG TA's that are 245/60-15 all the way around. I know this size will work, and all 4 rims are 4 in/4 out. I also bought a set of center caps with blanks where the Corvette emblems should be, and I picked up a set of Monte Carlo center cap emblems from a hub cap place in NJ. I'll add pictures once they are on the car. It should look pretty tough. The wheels and tires were a package deal, and I only wanted the tires. So I figured I'd try my hand at polishing aluminum. If it looks stupid, I'll sell the rims. There are plenty of Corvette guys out there that will pick them up. Stay tuned on that.

I looked thru all seven pages and didn't see this combo. Can anyone tell me if I will have any issues.
I want to run some American Racing Outlaw rims, 15x8 with 3-3/8" backspace on front and rear. Front tires are to be BFG 235/60-15 and rears BFG 255/60-15.
I have a '71 SS454, F41 suspension, big block with A/C. Original disc & drum brakes and I won't entertain wheel well lip trimming.
I will be putting in new OEM type front & rear coil springs this winter as my existing are a bit spongy. All shocks and control arms (F&R) have been re-bushed recently so suspension is pretty tight.
I raise the issue because I have these rims on hand, I really like the classic muscle look of these rims and I'm due for some new tires on the SS anyway. If these rims won't work, I'll stick with my 7" rallys and 235's all around.
Any thoughts?
Scott

You'd be able to run those tires on the stock rallys, and could even go 255s all the way around. That's what I did, and I didn't have to make any changes to the car at all. Just a thought, but the 8 inch wide wheels might be a bit too wide for the 235s, and those are going to be about an inch shorter than the 255s.

I'm not too sure about the backspacing though... Discount Tire (where I work) measures offset rather than backspacing to see what'll fit. Hope that helped!

Yaaa, I said I would post my opinions & results here with my set up after putting some miles on her, thanks for bringing this post up Malyc.

Im running 17 x 8 Rocket Racing Booster's with 4.5" backspacing, mounted with 255/50 17 Nitto 555's at all four corners. No rubbing at all, very nice smooth ride, exceptional handling and my WEAK A$$ 350 can barely turn over these sticky monsters. Well, maybe not that bad, but theres no way Im going to dig a hole to china with this rubber...

Completely stock worn out all original springs with booo cooo miles on them, 1 inch spacer (beneath coil) in rear

Nice setup there... After I get all the suspension work done (QA1 coil overs on all four corners, sway bars and whatever else I need...) I'm probably gonna go with a set of 17x8s with Michelin AS3s, though I think I'm going to go a bit shorter than what's on there now... 275/40s out back and 255/40s up front.

245/60/15s on Corvette rallys (15x8 with 4 inch backspacing) on all 4 wheels. Stock suspension and stock height.

The right rear rubbed on the fender lip slightly going over bumps. I bent the lip in a little and now no rubbing at all front or rear.

The fenders are rolled on my Monte also to accommodate the 8" rallye rims. Not sure I like it cause I would like to add the chrome moldings.

Mine is only rolled in a little and I can mount run the chrome trim without modification. I do know some guys who have to roll theirs a lot to get the tires to fit. It all depends on how centered the rear end is.

So after reading through all 8 pages I know a 295/50/15 and 325/50/15 will fit on a 15x8 with 5" back spacing (with trimming) but the wheels I want (Billet Specialties Street Lite) only come in 5.5" BS.

Will a 295/50/15, 325/50/15, 295/65/15 or 275/60/15 fit on a 15x8 with 5.5" BS? I dont mind running a spacer or massaging my inner fender along with fender lip trimming.

I would like to run this wheel but only if I could run a drag radial and street tire in the sizes I listed. 295/50 for the street and 295/65 or 325/50 drag radial for the track.

If they wont fit any of the tires I listed then I guess my only option is running their 17X9.5 with 5.5" BS and run a 295/45/17 drag radial for the track and size down to a 275/60/15 on a 15x8 with 5.5" BS for the street if that will even fit.

This would be a no brainer if they made these street lites in 5" BS. They also sell 15x10 with 4.5" and 5.5" BS which I prefer and I read on the Chevelle site that those will fit our Monte's but I dont believe it after reading through all 8 pages here.

Here's the Street Lite page
http://www.billetspecialties.com/wheels/street-lite/

15"


17"


I'm currently running the now discontinued frown 255/60/15 Goodyear Eagle's on my factory 15x7 ralley's as seen in my sig but they are old, cracking and in need of replacement.

Thanks in advance for helping me out. Ive already bought and had to sell a set of new rims at a significant loss because they didn't fit and couldn't be returned because I mounted a tire on them.

I think you are right on target with the 5.5" backspace and 1/2" billet spacer. I have the 325/50R15 Nitto 555R on a 15 x 8 with 5" back space. I actually still needed a 3/16" spacer on the drivers side.

I have a write-up on how to fit a 325/50/15 on my CarDomain page. Wow, I just clicked on the site and have not been to it in probably a year...boy have they changed it. My page and pictures are all messed up... crazy

Anyways here is the article...

I've been asked many times do I really have 325/50/15's on my monte and how did I get them to fit...when I say fit I mean even with the car sitting low in back, with the tires tucked up inside the wheel lip.
I have had this set-up on my car for over 5 years and it has never hit the lip...granted the lip is trimmed which will be necessary to use these tires. The inner sidewall will rub on the frame on very hard cornering or entering an steep angled drive...you will hear a squeek but no harm is done as the frame is smooth and the tire is just rubbing. One thing to point out here...this set-up is just for the cool factor of such a fat tire and the same traction results could achieved using a narrower tire.
A 325/50 has roughly a 13" section width on a 10" rim...now there is no way it will fit with that rim. You must use a 8" rim to shrink the sidewall down...which will bring it down 8/10". It will not even work with an 8 1/2" rim...I tried.
You will need a rim with 5" of back spacing and you still will have to use a 1/4" spacer. I have since purchased aftermarket axles (Moser) that are 1/4" thicker than stock axles which solved my spacer problem (racing with a spacer is not suggested).
The inner wheel housing will need to be massaged away from the tire...this will be self explanatory when you trial fit the tire and see where you are close. I used a mallet and you can not even tell that it has been altered when looking at it.
You can see in the first photo how close it will be to the frame (the daylight is the gap that you will have), it is a 1/4" to 3/8"...you see what I mean when I say you have to follow exactly what I did or it will not fit.
the second photo shows a view as though you were looking straight up at the lip and tire sidewall...there is a safe 1/2" of clearance there. I have my lip ground as far as you would want to go...the welded seam would be affected if you went any further...I then used por-15 on the ground area to prevent any possible chance of rust.

With all that being said I would do it slightly different next time...I would use a wheel with alot less b.s. for a deep dish look and have the rearend built (narrowed) around the wheels. This would look so much cooler (in my opinion) when seeing such a deep looking wheel (even though it would still be an 8" rim) it would appear or give the illusion of a fatter wheel and a mini tubbed look.

Yes, I've religiously followed your writings over the years but they dont make this wheel in a 5.0" back space.

So you dont think a 15x8 with 5.5" of back space will work, even with a 295/50?

Alright then, It seems I'm gonna be ordering the wheel I wanted! Billet Specialties Street Lite's in 15x8 with 4.5" back spacing for the rear.

Does anybody know what size 18's would fit on out car's? Their Street Smart line has quite affordable 18's which look better on Chevelles then 17's so I figure it would also look better on our Monte's.

I did some research and I only came back with Chevelle info but those seem to have larger wheel wells. Maybe order them in the same sizes as you would 17's?

Probably a good idea just to buy a wheel fitment tool like this one. Hopefully it can replicate tires size exactly because I dont like how 17"+ rims look with not wide tires out back.

I think just about any 18" wheel with close to 0 offset/ half the width in backspacing should fit... provided of course they're the right bolt pattern.

For me personally, I'd stick with 17"s because I like seeing a lot of rubber around the rim, but maybe I'm crazy like that. (Also mounting low-profile tires is a pain in the rear, but don't let that sway you =))
