Tobias Thonet Posted January 28, 2015 Share Posted January 28, 2015 Hey guys, so I was wondering about tire fitment. I have the stock 15x8 wheels, and I want to put 295/50 in the rear and 245/60 in the front (no, the front is not taller than the rear, I checked). I know the tires fit the wheels. I'm worried about the rear 295 fitting in the fender without issue. Also, and this isn't as important because it's a few years away, but whats the widest rim I should run in the Monte? I was thinking about some 18x10s down the road, so I can get some more high performance tires and give it that pro touring look. Quote Link to comment Share on other sites More sharing options...
Sam (Bones) Posted January 28, 2015 Share Posted January 28, 2015 if you have the corvette style wheels, with less back spacing, you will have issues with a 295/50, a 295/50 would probably fit with a 5 or 5 1/2" back space Quote Link to comment Share on other sites More sharing options...

And if that is adjustable? (before you say it, yeah I'm pretty un-knowledgeable about this stuff) Quote Link to comment Share on other sites More sharing options...
Sam (Bones) Posted January 29, 2015 Share Posted January 29, 2015 back space of a wheel is not adjustable Quote Link to comment Share on other sites More sharing options...
Tobias Thonet Posted January 29, 2015 Author Share Posted January 29, 2015 Do you know the backspacing on those rallys? Quote Link to comment Share on other sites More sharing options...
Sam (Bones) Posted January 29, 2015 Share Posted January 29, 2015 I "think" it's 4 1/2" Quote Link to comment Share on other sites More sharing options...
Tobias Thonet Posted January 29, 2015 Author Share Posted January 29, 2015 Okay, I'll measure it fur sure next time I'm in the garage, which won't be for a while. Thank you Quote Link to comment Share on other sites More sharing options...
502ci Posted January 29, 2015 Share Posted January 29, 2015 Backspacing is very critical when trying to fit large tires...do you have tires on the rims now? If so you will need a straight edge just slightly bigger than 15" so you can lay it on the lip and not have the tire sidewall getting in your way. I have a set of original Corvette wheels also and if I can remember correctly they were like what Sam said and are 4 1/2" or even possibly 4 1/4". I have them in storage otherwise I would measure them for you. Regardless you will have to measure yours when you get a chance because they could be aftermarket ones that have 5" of B.S. (which would benefit you). There are companies out there that can even remove the center section of your wheel and give you exactly the B.S. you want...will be costly though.

Tobias Thonet Posted January 31, 2015 Author Share Posted January 31, 2015 So since it doesn't look like the 295's will fit, I'm going to go with 255 since it's already on the car and I've read a lot of guys saying that's what they're running with not B.S. issues. Bill, no I don't thankfully. I'm probably going to but the tires before July because I'm heading to California for a month and my dad will want to move the car out of the garage Quote Link to comment Share on other sites More sharing options...
Malyc Posted January 31, 2015 Share Posted January 31, 2015 Another vote for 255/60R15s here, they look natural on the car and it rides pretty nice with them on it. I'll be going 17x8 w/ a 4.5-5" backspace with 255/45R17 Nitto NT555 when I get my suspension done, Quote Link to comment Share on other sites More sharing options...
LS5 Posted February 1, 2015 Share Posted February 1, 2015 I have 275 50 15's on my 15x8s with the standard offset and not rubbing but just by the skin of my teeth. Drivers side I had to trim the wheel well stainless and thats it the rear 1/4 was good on that side too. 295's must be slightly wider than a 275 ? in a 50 series. The T/A in a 275 50 15 is almost impossible to find though. Darren. Quote Link to comment Share on other sites More sharing options...
Malyc Posted February 3, 2015 Share Posted February 3, 2015 295s will be 20mm wider than a 275, or around 5/8", give or take a bit. Tire size is width in mm/sidewall height in percentage of tread width R (radial) or D (bias) and wheel diameter in inches for metric sizing, or diameter in inches x width in inches R (or D) rim diameter in inches. So, a 31x10.50R15 is 31 inches in diameter, 10.5 inches wide on a 15" wheel, and a 295/50R15 is 295mm wide with a sidewall height of 147.5mm on a 15" wheel. 1 Quote Link to comment Share on other sites More sharing options...
