I am looking at some tires in this size. I wanted to try the new Goodyear Duratrac but was told they wont be making this size for a few months. I really did not want BFG AT's because quite a few friends are running them and are not getting enough life from the thread on our roads.
A few others I have looked at are Cooper Discovery STT, Toyo Open Country A/T, and Procomp Xtreme A/T. Of all the ones I looked at, I think the Procomp look the juiciest. Has anyone had any experience with them? I run lots of pavement, some gravel, but not much off road.
Any others that might be recommended?

 

I run the Procomps and love them!!!
They are not too noisey, have a great ride and look, and I have about 45k mi. on mine and they still have a decent amount of tread left on them.

 

You should run those sized tires on a 9"+ wheel so the tire wears properly. I ran MT ATZs on a Weld 8.5" wheel and the centers wore out over the life of the tire. They do look good on these trucks!!

 

I have the Cooper STTs and they're great, but a little loud for my taste (very similar to Toyo MTs, but a lot cheaper). My next tires will probably be ProComp Xtreme ATs since they are offered in a 37x12.50 and I want something a little less aggressive. A 325 is pretty wide for stock tires, some better mileage options will be a 35x12.50 (or 305/70/18) or a 35x11.50 (285x75x18, offered in a few tires including the Toyos). The 285s would fit great on stock rims and will get you better mileage than a wider tire. They'll also stay under your fender more and keep the sides of your truck cleaner.
