Will 37's fit on a 5" RC lift?
 

If I get the Rough Country 5" lift for my 04 ram 1500 4wd will 37's fit? I know if I got a 6" they would but dont know about the 5"...any help appreciated

Also does RC have a 6" lift for my truck?

You need to consider wheel offset as well as the tire height. I can tell you that all I have on mine is a Rough country leveling kit - no lift, and I just mounted up some 35x12.50x17's on my -12mm offset wheels and have no rubbing issues whatsoever.

right now I have a leveling kit as well and have 34x11.50x17 nitto trail grappler MT's with a 5.5 offset
