I currently own a 2001 Sport 5.9L with a 5" BDS Suspension lift that got put on, the truck sits on BFG 315/70/R17. It is time for tires and I would like to go bigger, Ive been told nitto trail m/t will fit and Ive also been told they will not fit at 37's, ive been told yy techs i can do 35's in any brand that they stock without any problem, id like to fit 37's or find 325/70/R17 in a brand...ive been debating a body lift for clearence issues so i can fit 37's but not sure what road to go down? any ideas? thanks
