DO NOT BUY TREADWRIGHTS!
Read my thread in this section, as well as the other thread about them. i lifted my XJ 3" with the rusty's kit and some extras. I went with 31" Cooper STT and love them. With 3" of lift and 31's, you will probably be like me and need to trim your front bumper and the lower rear section of the front fender flare. Just for god sakes, please do yourself a favor and do NOT buy the treadwrights!!!!!!!!!
