Hey, I just bought 4 used 31x10.5x15 ProComp Mud Terrain Tires and had them mounted on a 1990 Toyota 4x4 SR5 V6 extra cab. The tire shop aired them to 35PSI. I just let out some air to 30PSI. They seemed to ride better/quieter at 35PSI, but I'm concerned about Tire Wear. Does 30PSI seem about right for these tires?
I have BFG KO 31x10.5's on my Wrangler, and they definitely ride better on-road in the high-30's PSI range. The shop originally set them up with 40. I haven't seen any weird wear, but I rotate every
5000 miles, or so.30 seems too soft for those tires on pavement.
What does it say on the side of the tire???
