Hey guys, I think I'm going to get some 18x10's on the rear and 18x9's on the front of my 2001 Cobra. What are the correct tire sizes for these wheels? What's the widest tire I can fit on the 10" rim safely? Should I just go with a 10.5 in the rear or are there problems with fitting it on the car?

Thanks for any help! All answers and opinions are appreciated!
