I have a stock 02 ram 3500 dually.I'm wanting to put a bigger tire on the stock rims (tall and wide). Will i need spacers between wheels. What size and brand did you go with ,Thanks Rick

2" spacers will clear 12.5's so that means 315's. Rears will stick out pretty bad tho and throw rooster tails and rocks all over the place. I hated them so bad I cut the hubs out of the inner rims, rolled rings and precision fitted/welded them to pull the inners in instead of pushing the outers out.

The width of the tires will be excessive for the 315's but I ran them without too much to complain for years (many a set of mud rubber) before going to big rig rubber.
