Newbie here needing some information. Does anyone know what backspacing I would need for 20x9's with 35s on a jku with a 4" inch lift? Help is greatly appreciated.

 

Minimum of 4.5" of bs, and wow 20" wheels! Those tire prices are going to be outrageous, less flex in your tires on the trail, and a harsh on street ride. 18's would be cheaper and still give that "big wheel look". Don't forget to gusset your front axle.

 

Just make sure to get Rockstars when you get your 20s.

 

The lowest you can get , mine are 3.75 BS

 

Why 20's ??
