Im thinking about getting some 20" axis matrix. The front is 20x9 with 255/35/20ZR and rear is 20x10.5 with 285/30/20ZR. I have stock supspension, do i need to roll my fender. Please advise, thanks.

 

It will depend on the offsets.

I have the same rim sizes with +26 front and +29 rear offsets and lowered on H-Techs.

I haven't had any scrubbing issues. I will have to roll the fenders if I go lower. You should be fine.
