4th gen rear and rim sizes
 

I need to know what the maximum tire size I can fit on an 18" rim in the rear with a 4gen rear in the car. Also what is the largest 17" rim/tire combo i can fit in the front. My car is a 91 z28. Mahalo

I think the widest 18" rear is 18x9.5 or 18x10. the widest front I've seen is 17x9.5 Sounds like you want some C5 rims https://www.thirdgen.org/messgboard/biggrin.gif
