So I've got my fitment on 19" wheels down with..
19x9.5 +15 w/ 225/40/19
19x10.5 +0 w/ 255/35/19

I was wondering if i switched to 20" wheels if there was any adjustments in offsets...like going less aggressive to compensate for larger diameter/tires?

I would be keeping the widths at 9.5 and 10.5 and probably tire setup 225/35/20 and 245/35/20

any help would be appreciated.

 

offset stuff should stay the same. only tire sizes are needed to account for extra needed room
