Will 255/40/18 on 8.5 ET32 wheels fit on the 4.2?
I am a little concerned by how the tire will rub the suspension/control arm upright. Anyone try this size on a 4.2?

were the aspect ratios 35 or 40? I'm debating right now b/c...

the 40 series will have a half inch more radius and hence come very close to the upper curved portion of the control arm. There's a little nub that sticks out of the suspension (arrow points to it in the pic). The pic shows the stock 255/40/17 5 spoke (17x8 ET35). That extra 1/2" up higher from the stock tire looks mighty tight! If you ran the 255/40/18 on the same size wheel, i'm good to go. otherwise, i will either resort to a 5mm spacer or go with 255/35s. Bummer. I spent this whole morning getting all excited to get some wheels on and ran into this issue.

Also, remember that i'm going from an 8" ET35 to an 8.5" ET32...
the new wheel would be 3mm CLOSER to the suspension upright given the 1/2" increase in width. the change in offset really doesn't help other than push the wheel 9mm further out on the outside of the wheel.
