wonder what tire pressure do people who have the above tires run when cruising on Highway. I put 40 psi all around in mine and don't know whether that is okay. Driving with it seems normal though.

No, use 60 - 65 psi all round

That is a blue gill imposter...don't put your tires at 60-65.

#1Due to the "rounded" tread area of the MT's (when viewed from front or rear of truck looking at profile of tread) the tire should be run at 30-32 front to back respectively. The reasoning is that you want to distribute the weight of the truck over the tread as equally as possible. Higher psi will give you uneven pressure points across the tread pattern. Where the center of he contact patch bears most of the weight-this is a bad thing.

#2Because MT's have a large amount of "void" area (places without rubber) there is a smaller surface area of tire touching the road than you would find on an AT. Conventional tires have small voids and lots of rubber touching the grund. To make up for the difference, Your tires should sit at 30-32 respectively. This gives you greater surface area in the realm of a circumferential improvement and as stated in #1, a better distribution of load over the contact patch.

That is a RVR OVR imposter...but don't put your tires at 60-65 either, it's just dumb.
