Alright folks, if you have any knowledge on my issue it would be greatly appreciated...

I have a 96 TA WS6 currently wearing 255/40/17's on a 17x8.5 C6 Replica Rim (unknown offset) on the front and 295/30/18's on 18x10.5 C6 Replica Rims (unknown offset again).

I just ordered replacements as the chrome is flaking on the existing rims. I ordered the same exact rims, except in the front I ordered 17x9.5 and have 275/40's I'm going to put on them. The offset is +58, which is actually 3mm beyond what the car's range is supposed to be, but it seems that is inaccurate because C6 wheels are very popular with Camaro's/TA's from this generation. Will 275/40's, Sumitomo HTR Z III's, fit on my front without rubbing?

Perhaps more generally, what is the means of determining how big of a tire (section width wise) can be put into a front wheel well?

4th gens can fit 275-40-17 sized tires in all 4 corners - many came with them from the factory.

3mm is about .12" or 1/8 - not so much in real differences - tire variation between brands is much more than that...

I didn't find anything online or in the service manuals stating that 275/40/17 is the stock wheel size, but I found some websites (possibly unreliable) stating other sizes. Where could I find out that information other than through a forum?

I do appreciate the feedback. I did do some bad typing by the way, unfortunately. I put 96, but my car's a 97, I fat fingered that one... and the 58mm offset is actually 4mm higher than it's supposed to go, not 3. I know, no big deal still. Just correcting my own mistakes.

Sizes To Fit Your Vehicle

Check that link out at tire rack.

Of course, 4th gens did come with 245-50-16 tires on 16" wheels, but 17" was OEM also.

A buddy of mine had a 97 TA also - he bought chrome ZR1 17" x 9.5" wheels and they fit perfectly with 275-40-17 sized tires, bought them from SLP when they still carried them.

Awesome man, thanks for all of your help.

Since you seem to be know a thing or two about wheels, I'm about to post a new thread about nickel shadow on brand new chrome rims, not on the face of it but where the tire will be covering it. Purely cosmetic (which wouldn't matter to me since it's not showing), or something to worry about?

I own a company that specializes in 3rd gen wheels...

Honestly, my knowledge isn't really based on chrome wheel finishes, but do know that a lot of aftermarket wheels suffer from poor chroming jobs that can start peeling after a few years. Research the finish before you buy.
