I will be needing some new mud tires soon and i am trying to figure out just how big i can go with out having too much rubbing or power loss. I currently have cooper stt 285/70/17 (33-11.5-17) which fit with no problem. I have been looking at the toyo 295/70/17(33.5-12-17) and the bfg km2 305/65/17 (32.8-12.2-17). Im leaning toward the toyos but need some opinions on them. (Truck is a 2006 sierra z71 5.3L with 3.42 gears)
