Hey I have a 1995 C1500 truck. I want to put aftermarket wheels on and I do not want to do any modifications to the wheelwell. Does anyone know the maximum wheel size I can put on the truck? (i.e. 17, 18,20?) Thansk in advance, Deven

20" with a 2-4 lowering kit looks good on full size trucks, and you still have pretty good clearance left. Anything over 20" on a stock ride height looks bad.

Thanks a lot. But I have one more question....how hard is it to do a lowering kit? Thanks in advance

If you get a good lowering kit with leaf springs and spindels, it's a little harder. My friend and I did it on his Sonoma and the spindels we did ourselfs and the leaf springs we got a shop to put them it. You can do it yourself if you have the right tools.
