What spacers are recommended when running stock wheels with 35 12.50 r20 tires?

We have seen customers use 0.65" spacers to provide adequate clearance.

Will I need spacers to run 35 12.50 r20 tires?

Kryptonite Products Team

If you are running stock wheels or wheels with the same backspacing as stock then you will need a spacer as the inside of the tire can hit the control arm near full lock.
