I'd like to have a little better fitment, so I'd rather just get a bigger wheel and tire. Could anyone tell me a better wheel and tire size for our car?

I have the same question. I want to go for bigger tire and rim size but confused on what to get. I am currently checking out tire and rim selections on 4wheelonline. Hopefully, I don't end up buying a combo that would have any rubbing issues on the G6.

The GTP and GXP are one size larger with 225/50-18. That's the biggest diameter tire you can fit without rubbing problems.

Thanks for this info! Definitely helpful!
Not true! I have 235/50R18 on my GXP 6. No issues. Had 245/50R18 on it as well. Had a little rubbing on plastic inner fender well. Only when wheel was turned all the way. The 235s are perfect. Eagle F1 performance summer tires. I only drive it in the warmer months.
