Has anyone tried fitting the stock Ss tires on a set of 20x10 front and 20x11 rear wheels? Stock tire size is 245/40/20 Front and 275/35/20 rear. Just curious cause I just bought some 1LE wheels and might throw these tires on with a bit of stretch cause they have a lot of life left. Post pics if you have!

I was in the same situation when I bought my new wheels in 1le sizes. I ended up putting my 275/35R20s from the rear up front and I bought new ones for the back.

What size did you end up buying for the rear? And you don’t think the stock tires as is would work at all? Thanks!

That tire/wheel combination won't work. Will stretch the sidewall too far to have tires work reliably. Will mess up how the tread contacts the road, too.

You'd be better off putting the rear SS tire on the front 1LE wheel like Drew did, and then getting as similar of a tire you can get to the stock SS tire in a size between a 295-315 width and a 30 AR on the rear. Or, better yet, try to find a used set of 4 matching tires that are the proper sizes for the 1LE wheels. There's usually a decent selection on here and even some floating around on other sites.

I agree with the 275/35 on the front but not the rear, too wide. Ofr winter use I have a 285/35 on the 1LE wheel and it's perfectly fine so you can go 285/295/305 and either 30 or 35 in the rear. 305/35 might rub the fender liner and harness but that's easily corrected.

Yeah, I put the 275/35R20 up front and put 305/30R20 on the back. No issues with that.

I would go ahead and invest in new tires of the right sizes for the wheels you bought. You can advertise your stock tires on Craig’s List or eBay to sell them to a Camaro owner who is looking for used tires with good treadwear left. I know it is expensive but that’s probably the best solution for you now and I really think you will enjoy the car and new wheels/tires better too as it will make a difference in the ride and handling!��

You can move the rear OEM tires to the front, it will fit the 20x10 wheels just right—your problem is what tires to get for the back 1) to meet the bare minimum requirements for the wheel you purchased, 2) to keep the front to rear sizing balance, 3) not to introduce a huge difference in traction and ride characteristics between front/rear.

The OEM Goodyear runflats do not come in a size (295/30-315/30) that is suitable for 1) and 2), and I wouldn't recommend buying another brand for the rear due to 3), the OE runflats have terrible wet behavior I've witnessed firsthand, coupled with great hot dry traction that is going to be difficult to match.

For these reasons, I agree with LT4Greg, bite the bullet, get some proper tires for front and back and enjoy them long term. Sizewise you can go with the 1LE specs (285/30/20 front, 305/30/20 rear) that is a direct fit for the wheels if these are the OEM 1LE ones, or you can go a bit bigger like I did (285/35/20 front and 315/30/20 rear), you might even be able to make 325/30/20 work in the rear.

Thanks a lot for the input everyone! I ended up getting a set of 305/30/20s for the rear and moved the original rear wheels to the front

[LT4Greg]

I would though get some 285/30 20s for the front wheels when possible! The ride and handling will be better!��

I think you made the right call here. Worst case, you now have two good full-size spares (unless you've managed to sell or otherwise dispose of them).

As far as the tire industry is concerned, it's only the 245/40's on 10" wide wheels that's outside the recommended range of rim widths (9.5" max recommended). 11" wide wheels are actually OK'd for mounting 275/35's on.

I’ve seen some guy on YouTube temporarily use the stock ss tires on some 20x10 20x11 wheels though and they looked pretty damn stretched

"Stretched" is a tire&wheel appearance that most people who specifically consider themselves "musclecar fans" have a hard time understanding, simply because it looks different from what they're used to seeing. Perhaps a wide wheel makes the tire look undersized to them.

It's easier to appreciate a little stretch when you're more into hard cornering than straight line acceleration - once you've settled on a tire size, stretching it a little improves its cornering capabilities. Somebody who understands stretch (within limits) would see wheels chosen to emphasize cornering with the appearance being whatever it ends up being (function over form).

Exactly. To expand on the "within limits" thought, I'd think anyone looking at tires would want to avoid stretching past the recommended range from the tire manufacturer for a current Camaro. They've already got plenty of cornering stiffness on the OE setups to reach the tire's max lat capability (either from a 30 AR sidewall or from ROF tires). All stretching more would do is further increase cornering stiffness which requires less slip angle to reach nearly the same amount of lateral force. Depending on the driver skill level, this could actually make someone slower around a track since everything would be more sensitive to drive input. Might even cause damage to ROF tires if driven like that for very long like in the video posted above.

I think part of the knee-jerk reaction to hearing "stretched tire" is what people think of when they hear "stretched tire." For me at least, first thing that pops into my mind are tires stretched so far there's a 1/2" gap between the rim flange and the sidewall. Sure, a ridiculously stretched tire has it's place in drifting because they want the excessive lateral stiffness, but there are those that do the same thing for a street car and say it's for performance. If that's what floats their boat for looks then I say go for it, but it bugs me when people do that and try to say it's a performance benefit. I personally don't consider mounting a tire within the manufacturer's recommendation to be stretched, it's more just the standard for a performance car.
