I just was given my first truck. it is a 2002 gmc duramax. I installed a 8" lift kit and 37x14x20 inch tires. I am looking to downsize to a 35 inch tire but I don't want the truck to be top heavy. so should I run 35x12.50 or 35x13.50? thanks - - - Updated - - - or any tire size u think will look good.
