Largest tire for 15x6's

[lethal231ci]

What is the largest tire I can go with on 15x6's without rubbing or sticking out too far...has 3 1/2 back space

Technically, you could probably get away with a 235/60-15, but to be safe, I would say 225/60-15 and ride. Remember, stock 15x7 wheels for both GNs and Ts came with 215/65/15s. Why not go with a narrower tire like a BFG Traction T/A 205/70/15 for the skinny look? Looks really good with wide tires out back if I do say so myself.

Hope this helps.
