275/40s on a 10" wheel? - Page 2 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Doc · 07-22-2012, 03:00 AM

If you're going to run 275/40's look into getting a 19" wheel. I have 275/40-19's on all 4 corners; the rims are 19 x 9.5" with I believe a 28mm offset. There are no clearance issues in the front although I have Pedder's coilovers which might help.

Try and reduce the unsprung weight if at all possible. If you're not going any bigger than a 275 in the front just get a 9.5" wide rim. There's no advantage to using a 10" rim and you're just adding unnecessary weight. The optimum rim width for a 275/40 is actually 9.5" so they fit perfectly. If you can knock 4 or 5 lbs off each wheel by only going as wide a rim as necessary, and possibly a 19, you'll be amazed at the difference in the car's performance.

Not sure why you're doing the wider tire in the rear unless you're doing drag racing maybe? With 275/40's all the way around my car has plenty of traction and handles great. I got 3-piece forged rims and even though the fronts are 1.5" wider than the stock wheels, I still removed a total of 30 lbs of unsprung rotating weight for all 4 by switching to 19 x 9.5's compared to the factory 20" wheels. The effect on acceleration and braking is like removing 300 lbs of static weight from the car. You can definitely feel the improved response.

I meant run 275 or 285 all the way around.

Am I looking at a ton of stretch? Anyone running this setup?

Thanks fellas.

this is 275/40-20 in front, 315/35-20 in rear rims are 20X9.5 in front and 20X11 in rear. Offset: +32 front, +45 rear
stock height on car, no clearance issues and handles great

Car's my DD, don't have the resources to buy separate wheels/DRs for drag, so these tires are gonna have to cut it for weekend circuit and drag racing. Plus they look great from the back.

315 is a bit wide for a 10", usually recommended 10.5 to 12.5, would probably have a bit of bulge.

the fronts should be fine as long as your offsets are cool.

Im running 275/40/20s on my ZL1 10 inch rim (fronts). Here are a couple pics. I have a couple more if needed, lmk.

I have 275 40's on 10" rims on all corners. Might want to look at the BFG G-Force Comp2 Tires. I had the Invos and they did look a little stretched. I did not like them and switched to the BFG G-force because they have a little wider thread width than the Invos. I am much happier.

Revo1 · 07-23-2012, 02:43 PM

Good advice, thanks

How do you like the comp2's? I've heard mixed reviews.

This is what it shows for comparing stock front verses rear wheel-tire combinations and what you would see if you placed a stock rear wheel-tire combination on front.

Please consider using to help make your choice for new configurations.

Are these sizes the stock SS sizes? If not what are the stock offsets?

JRT · 07-23-2012, 08:18 PM

What he posted was stock size and offset for the 20's +35F/+40R.
