Thanks sigar! I am running LT295/65R18 Goodyear Duratrac tires. The only suspension modification I have made is a 2.5" leveling kit from HBS. http://www.hellbentsteel.com/ The 295/65R18's did not rub at all before or after the lift. I could have gone with a little bigger tire actually. The Duratracs ride good, and after 5K miles are wearing pretty well too. They are very quiet for such an aggressive tread pattern.
