[Camaro1LT19]

Hello, I am wondering whether i’ll be able to fit 12” wide rear tires on my 6th gen Camaro 1LT. I’ve been looking for wheels recently and came across a set of C6 Corvette Spyder wheels. The fronts are 9.5 inch wide but the rears are 12 inches wide with 325 wide tires. I am aware that the ZL1 1LE has similar wheel specs on the rear, but I am wondering whether the trim level makes any difference. If anyone could help me out that would be much appreciated. Thank you.

I'm 99% sure they are different bolt patterns and will not be compatible...

they’re both 5x120 so i don’t see any reason the bolt pattern wouldn’t work. unless there’s some other difference that i’m not aware of.

There was another thread on here not long ago asking the same thing and there was a bunch of info about the bolt patterns not matching up...

Check the bolt pattern and offset on the Corvette wheels. Corvette wheels tend to have a larger offset than Camaro wheels and will probably not fit without spacers. There are numerous threads about wheel fitment in the Wheel and Tire section that will help you find new wheels for your Camaro.

It will NOT fit.

Offset is wrong

[LT4Greg]

Yep offset is different on a C6 Corvette.

If they are off a C8 then the bolt patterns are the same. But no C8 has been released yet with 12" rears. So if these are off any earlier generation Corvette, they have 5x120.65mm (5x4-3/4") bolt patterns vs the Camaro's 5x120mm. They are close but not the same will not fit properly. I'm sure they'll also have way too much offset, but that could be dealt with using spacers. However, the bolt pattern would make it a hard nope regardless of offset.

Hi MSquared, I know you have a lot of technical knowledge pertaining to the subject so I'm surprised to hear you say this. You think the .65/5=.13mm or 5 thou off center would matter? I would think it's well within the allowable tolerance and have heard of many people running these without issues, no wobble bolts needed.

With that said, to the OP, the corvette wheels typically have a very high offset and I doubt most would fit (maybe the fronts as a square setup but again would probably throw your scrub radius off). I certainly wouldn't want to. Typically the corvettes hide a lot of the wheel behind the hub (towards the center) and use a very flat faced wheel. I prefer a little concavity fwiw.

That an the wheels are hub centric an I beleive the hubs on Vettes are bigger than the hubs on a Camaro.

It's not 0.65mm/5. In the very best of circumstances, it's 0.65mm/2 because the bolt pattern is a diameter and it could be split into radiuses. However, the reality would be that the first lug nut you torque down would locate the wheel perfectly on it, and then the lug nuts most opposite of that would have the full 0.65mm mismatch. So the difference is 0.65mm or 25/1000ths of an inch. And yes, I guarantee it matters. Try bending a wheel stud 0.65mm at a distance 1/2" past the hub flange mounting surface and tell me how much force that takes. It will be pretty epic. More likely, you'll end up wallowing out the tapered lug nut seats in the wheels in unequal amounts, so your wheel won't be centered and won't be located the same way twice.

No wheels are really located by the hubs. They are always located by the tapered lug nuts and the receiving seats on the wheels, and held there with the friction from the clamping force between the mounting surfaces of the hub and wheel. Since the pilot bore of the Corvettes are bigger than the Camaro's, that won't hurt anything. However, because the hub bolt pattern doesn't match the wheel's bolt pattern, the wheels won't be properly located.

Yeah you're right its divided by 2 not 5, which on paper is 12 thou. There is some added clearance though, not sure what they spec. I've heard of many people doing this without issue. I would think it comes down to installation - if it's evenly torqued, alternating often, I don't think it would be close to the full .65mm, I get what you are saying though.

By design there is zero clearance with a tapered lug nut and seat. That's what locates the wheels, and they are torqued to a literal interference fit. At best, this ensures that every stud is being bent .012" when the wheel's installed. In practice, it means that the stud for whichever nut you tighten first is probably not bent at all, because the wheel locates primarily on that stud, and then all the others are closer to the full .025" bending.

That's for the first time you install the wheels. After that, what probably happens in that you wallow out the seats in aluminum wheels and then you have clearance. However, that isn't a good thing because it means you have minimal contact at the taper and then the nuts don't have the same force keeping them tight. It also means the wheel is located as much as .012" off center.

Man I need to finish my morning coffee (insert excuses here). Yeah I mean there's clearance in the hole, like a good amount, but it's going to locate to the taper, not the clearance I was thinking of. I'm surprised more people haven't noticed an issue. I've never done it but I know tons of people who have done it without issue, guess I will continue to not do it. Maybe they use wobble bolts, another thing I have never tried.
