I'm looking at a set of camaro wheel/tires that came off a g8 but the guy selling them said it rubbed a little in the back. His tire sizes are 245/40/20 and 275/40/20. Does anyone think this setup will work with no problems? He didn't say how bad it rubbed or if it wasn't going to affect anything. I don't know if it helps but I don't keep anything in my trunk and I never have people in he back seat (as far as weight goes to lower the back of the car but not sure if that even matters.)

Typical specs are 245/35/20 in the front and 275/30/20 in the back. Are you lowered or stock height? Since stock 19" wheels are 245/40/19 and assuming you're not lowered, you should be able to fit without rubbing issues (assuming no weight in the trunk or back seats). I may be missing something though.

I guess I'd be questioning why he's selling them in the first place. A "little rub" is very subjective. I ran the calculations and it looks like the difference between a 275/40 and a 275/30 tire is 1.09" or so. I know people with 275/30/20 can lower 1" without rubbing issues but when the car is loaded up, they'd rub when hitting a dip or a bump in the road. I think you're good to go! Good luck, just don't lower it!!

The tire is actually 2" taller, which is over 7% larger, definitely not recommended. I'd replace the tires with something properly sized as soon as possible. Also be aware that at an indicated speed of 60MPH you'll be closer to 65MPH.
