Wheel and Tire Data Base.

Recommended Posts

Original post was deleted by accident so a new one is started. Repost your wheel and tire combo here so we can have the list again of what fits our cars.

List wheel size with back spacing, tire size, any quarter panel trimming needed, spacers if used, airshocks if needed, spring spacers, wheel tub modifications, etc...
Also add pictures so we can get see how they look. 😎


Example:

15x7"wheels with 4" of back spacing front.
15x8" wheels with 4 1/2" of back spacing rear.
255/60/15 front tires.
265/60/15 rear tires.

Great idea! Got me wondering, how to set a data base like this up? Excel / Google Sheets? so people could search after it gets 100 entries.

If you like, I can add all STOCK data for the three years but I don't have that information.

Hi all!

 I am looking to replace my current 245/60 R 15‘s. 

 I am thinking about going stock with 215/70 R 15. 

70 is also pretty high;  is there a shorter tire I can go with? 

 How much handling will I be giving up? I live amongst curvy roads. Thank you.

Hello again Helen. Depends on how you drive on those curvy roads. The skinnier tire will adversely affect the road manners of your Monte. Do you have the 245's on all 4 tires? 

In the new members section I believe you said it's a 350 car. Since you are on curvy roads alot I suggest bigger sway bar in the front and  boxed lower rear control arms with a rear sway bar. Even the factory F41 arms and sway bars would make a huge difference in the way your Monte would feel. Hope this helps.

Thank you.

 I am stuck somewhere between keeping a nicer handling package, or going more stock. See previous response.

Hi Helen, welcome to the insanity 😁 You have just ventured into the keep it stock or upgrade for whatever reason cloud 😯 I can't speak for your winter conditions, but on your roads i'd want more rubber on the ground. Unless your at Pebble Beach I doubt anyone will question your going to a 60 series, I'm running 225-60R-15's. The original stock G70-15's had a tread width of 6.70 and a section width of 8.50. In contrast my 225's have a TW of 7.5 and a SW of 9. Didn't want to go all tech on ya just some data to ponder. There are lots of handling upgrades but ya have to have some good sneakers on our heavy Monte's.

Bruce, according to my sales paperwork the 70 came with either G78-15 or G70-15 tires .

I have 215-70r15 redline radials on my 72 car has all factory springs and tires fit fine. The shorter the tire the more of the "road"you will feel.
