I used the search function and did not find what I was looking for. I have 35's on the way and need to know what psi to run them at all the time. And what they can be aired down to with a 9 inch rim.

 

Try the Wheels & Tires FAQ stickied to the top of this section. It's a long shot, but there might be some info in one of these areas...

 

I run my 37s at about 30psi on the road and between 12 - 15psi off.

 

We run on 35's on a 17x7.5" rim at 28psi on/15ish off.

We did a chalk test and it wasn't as telling as I hoped but it did show that with my setup 30 or 32 my outter edges weren't touching much, that with 26 the entire suface was making contact. We compromised a little and run 28ish.

 

Yeah like Flamered said do the chalk test youll come out about 26-29 PSIG

 

I run 26 to 28 on the road. Off road varies (depending on terrian and how serious I am) between 10 and15.

 

We are running 35" km2 with 17x9 wheels and on road for comfort run 28-30psi but for gas mileage 35psi. As for off road we run 15psi.
You'll probably get a million different answers for on road psi but that's what we run

 

Gabe - you are too anal! can't wait to see you and Jen again at Rocktoberfest! And absolutely, positively, no chalk talk at that time

 

I run 28psi on and 16psi off-road (rocks). I have very little wear after 10k miles.

 

I run 32 on road and 15 off road with 35/1250/17. I have about 25000 miles on mine and have another 10-12000 to go. Perfectly balanced still at 85 mph.
