i currently run 4 trxus sts radials but with the new charger etc the truck just wont hook on the sandy loose tracks i pull on so i need to run duals in the rear to get anything going my question being no one has a 33x12.50-16 sts anywhere i've found plenty of the bias ones would it hurt me to run the 2 bias in the front and the 4 radials in the rear?
