What kind of miles are you getting out of your stock KO2s? I have 16,500 miles on mine and they are down to 4/32s! They were rotated so the wear is even on all 4. I am hard on tires and hoped to get at least 25K but 16.5K is weak. Oh well Ridge Grapplers getting installed on Friday. DISCLAIMER: I do accelerate hard because it is fun in the Raptor!
