do the 1LEs use ZL1 front wheels (width and offset) all the way around or are the rear wheels a different offset 20x10?

The 1LE uses ZL1 wheels (10" front, 11" rear), but with 285 tires all the way around.

I dont think the 1LE uses 11" rears... there would be no need for it. Goodyear lists the absolute MAXIMUM recomended wheel size for the Eagle F1 G:2 as an 11" width. Doubt they would balloon a 285 over such an unnecessarily wide wheel. Quite frankly it would also be a waste of money for GM.

Here's the info from the 1LE section:

http://www.camaro5.com/forums/showthread.php?t=212140

I don't see how that would be a waste of money if they have it in inventory already?

Oh, and welcome to Camaro5.

I guess you're right, theyre using 11s, but my point about wasting money is even though they may already be in inventory, more material always costs more money... why spend the extra when you (GM) dont need it for the tires youre putting on them?

Thx for the welcome

All of the parts that are used for the SS performance package (1LE) are taken out of the ZL1 bins (Corvette for the Transmission), thus there are no extra design, testing and production costs associated with making those parts. If you're just talking about the cost of a tire size over another, think of it this way, if they are stretching a tire over a bigger rim, then that's cost effective as opposed to putting a bigger tire that would maybe be an additional what $20/per? If they are putting a bigger wheel to help eliminate the understeer for the purpose of this car, don't you think that is worth the little extra cost?

I'm just asking...

Does GM publish the exact offsets, back spaces, dimensions of the ZL1 20 inch front and rear wheels ?

Why can't somebody just measure/analyze the offset & back space on the
front: 20x10 wheel and the back: 20x11 wheel and publish the exact engineering drawing/specs on this ZL1 forum instead of guessing ?

Maybe ZL1 owners don't want to get dirty.

The above pic is someone's guess using a online offset calculator.

I have a 2010 SS. If I ordered the F1's in the size for the ZL1, will most tire shops know how to properly install it? I have a friend that put them on his SS, and a ZL1 owner that said the tire will work fine on it, but when I see this talk about offset I'm starting to wonder if there is something I've not been told.

Was looking to order them within a couple weeks, so I appreciate any insight.

Just ask Doug, I know I was not planning on lowering my car so I went with the 10" with 23 offset all the way around. If thinking of lowering Doug says 35 offset. Actually here is the post with the sizes: http://www.camaro5.com/forums/showthread.php?t=292326

I think they look mean as hell with the 23 offset.

I am not sure if you are asking if you can put them on oem SS wheels, but the ZL1 oem tires will not work on SS oem wheels. I guess you can make them fit, but not recommended, even by the manufacture.

If you are asking if the OEM ZL1 wheels and tires will fit the SS, then it is no problem.
