My buddy has a '99 Scrambler 500 4x4 and he wants to install Razr's. The stock size is 23's in the front, 22's in the back. He wants to go 22's in the front and 20's in the back. Any of you guys running this settup? If so, does it mess with the 4 wheel drive at all? (Most of the time when going up or down in tire size, you go up in equal amounts both front and back, but he's going down 1 size in the front and TWO in the back)

Thanks for the help.

 

He would be better off going 20" rears and 21" fronts. He will only loose 1/2 inch clearence up front but it would be wise to keep the same 4x4 ratio.

Many have done these sizes with no problems.
