Rim Width for GY's
I just bought a set of Z06 wheels from a buddy that are 17x9.5 fronts and 18x10.5 rears. I currently have 245/45ZR17's and 275/40ZR18's GY Eagle F1 A/S tires on the stock wagon wheels that came with my
'97 when I bought it used last year. Will these GY's fit these rims?

Take a look at this tire data calculator. According to it, the 275-40-18 inch tires would be ok on the 10.5 inch rim but 9.5 inch rim would be a bit wide for the 245-45-17 inch tires.

Your original GY tires are at least 11 years old, industry recommends replacement after 6 years (might be conservative). Look between your tread, in the valleys, (and sidewalls) for any sign of cracking. I would not be doing any HPDE or high speed cruising with those.!
Plus they must be hard as rocks (ride rough), and get little traction.
Ignore my response, I just re-read and saw your tires were GY F1 A/S, those are NOT the original tires.

Someone posted a picture of a 275 on a 10.5" rear (on another thread) and you could actually see how the wheels were the outermost part of the wheel/tire. Definitely not a good thing if you want any curb rash protection against your wheels.
I made the mistake of buying a set of Z06 wheels without realizing this. I ended up buying a set of Firehawk Wide Ovals in the Z06 sizes. A $1000 mistake. Oops!

Yes you can do it but it is not recommended... you will stretch the sidewall, giving a European look... it will also open up the bead area exposing your wheel to curb damage...
I took a picture at a car show of someone who had done it...
it is particularly noticable on the rear wheel....

I'd go with the stock Z06 size tires - 265/40ZR17 and 295/35ZR18.
