i hope you guys can help me. I have been looking at wheels and tires. I thought i wanted 20's, and while i do think they look great, the tires are just too small in the rear. I guess i am out of style, but i wanted wider bigger tires in the rear for the old muscle car look. Do i need to just go with 18's? Can you put a bigger sidewall on the 20,s???? If 18", what is the biggest widest tire you can run?

 

Sounds as if you need 18x9's rims for the front and some 18x10's rims for the rear. You could fit them with some 255/45 on the front and 285/40 on the rear. That would give you that rear muscle look your seeking.. This one was featured in MM feb issue..
