I have a 5/6 Drop on my ranger and i was wondering what is the biggest tire and rim size i can put before the tires start to rub
thanks

Kind of a loaded question. I would imaginewith the right offset you could a 18 or 19 inch wheel and around a 225/40/?? That is speculation though. I ran the stock 14's on my 5/7 with minimal rub. When I say minimal it was only when I hit a big bump.

I would say a 18 with 225/40's would be the biggest
