A few guys have 35"s, more have 315's (essentially a 35) on H2 rims. You'll have to trim a fair amount on the air damn and the pinch weld to get 35"s to fit, or just trim the air damn only and squeeze 33"s in there.

so a 305/75/16 would be fine?

friend called me said he was riding around town on 37's with a leveling kit on the front. Said it rubbed a little bit when he turned it all the way. I'd say if you cranked them all the way 315s, which is what I'm about to put on mine with a leveling kit and new shocks.

Im currently running 305 70 16 on mine with the torsion bars cranked all the way and I did a little triming of the front air damn and it rides great. The only thing you got to watch for is the bigger you go that you watch for how it fits your wheel. ALot of dealers will tell you that on stock rims you SHOULDNT go any bigger then 285's on 16 inch rims because of the way they fit. IMO it is up to you and how far you are willing to push the safety issue.

X's 2! Aren't the stock rims only like 7" wide? I remember my 285x75R16's bulged alot on the stock rims and a 305x70R16 is wider than that. Just try to keep safety as a factor! I did, and bought new rims! Mainly cause they look good though!:D

I believe a 305x70R16 is the equivilant of a 33x11.5x16 it's on 1" wider than a 285x75R16. Watch your inner fenders. My 285's on ProComp rims just about torn the inner fender out when I hit a bump once!
