what tire size should I use?

[wantsanS14]

what would be the perfect size for a set of rims 18x9.5 rear and 18x8.5 front?

also, what brand would be the best.

Depending on the hieght that you want, you have several options.

I run 235/35's up front, and 265/35's out back on the RX7. I have 18x8.5's up front. I have 18x9.5's in the rear. I am runnning Maxxis MA-Z1's (I get them cheap).

On some cars you can go larger. What car? Offset on rims?
