Question - Tire Size For 20/21 Wheels On a GS or Z06
For those running 20/21 wheels on a wide body, what tire size and brand are you running that does not rub? Thanks in advance.

Discount Tire, if I went from 19/20 to 20/21 using the same width on the new wheels;
- what is the widest tire I could put on the rear without rubbing or causing any issues? Would it be 325/25/21?
- would the 285/25/20 still be the size of choice for the front using stock width, again, without rubbing or causing any issues?
- I am thinking about moving from the OEM tires to the all season run flats in the "21" size because I am hearing the ride is better, and they are quieter. Since you know the tires, is that accurate (ride better and quieter)?
Thanks in advance for your info and assistance.

Just FYI, I run the 20/21 combo on a non-widebody. My rear wheel is 11" wide and I run 295/25s. That's probably as narrow as I would go on that wheel, so I'm not sure that's going to fit well on a 12" rim. Just something to ponder.
