hello everyone, i have a 07 chevy crew cab lbz, and i just got some new wheels at discount price. i got 20 inch incubus rims , but the tire that are on them concern me. the tires are the Wanli (HP) S-2085, i am pulling a fith wheel , gross weight is 11k, i am wondering if these tires could handle the load that i am pulling , or does anyone know what would be a good 10 ply tire. Thanks .
