I have an 04 rcsb that I want to do a 4/6 drop to ....but I need to know what size tires I will need. I am running the stock 16" wheels.....also I was wanting to know what size I should use on my 20" wheels. any help would be appreciated..........

 

Stock wheels and tires will work fine with a 4/6. As for the tire size for the 20s, depends on width and backspacing/offset of the wheels. Most common on a 4/6 are 255/35/20, 245/40/20, 255/40/20, and 275/35/20.

 

I am running 275/40/20 with 5.5 back spacing. See sig.
