I need tires so I want to know what tires are good on these trucks. Are the cooper at adventures too light of a tire for this truck? I also found mickey thompson baja stz for 135 but I don't know if these are rated for the truck. I called every tire place thats a franchise no one at pepboys or firestone or walmart will put bigger tires on it or do a front end alignment because its a lifted truck. So i'm going to buy the tires and get my gfs dad to put them on so I need some help finding a good tire. Truck is a 2500 silverado ext.
