I am looking to up grade to some 18" rims. I think I'm going with Moto metal 956 for the rims, but can't decide wihich tires to go with it. The size I want is :325 60 18. The brands I've found with this size are: Toyo A/T, Cooper STT, Nitto A/T and BFG A/T. I was wondering if anyone has ran the Cooper STT's, and if so how did you like them? Was there any balancing issues and how did they wear? I really don't need this agressive of a tire for daily driving, but I do pull a trailer daily and put heavy loads in the truck bed often, and these tires have a load rating of 3700. What do you guys think?
