Have a 2011 Raptor, stock 315 70 17s D KOs were taken off at 70k, had 6/32 left, rain and snow performance was worsening. Replaced with KO2 E have 19k on these with no wear from new measurement. Son replaced stock tires on 4 runner trail premium with KO 2s E rated had no measureable treadwear at 35k, now at 55k the siping is starting to disappear. Manager at Discount Tire tried to discourage E rated on 4 runner, handling much better than stock C rated. Border Patrol went to E rated KOs a while back due to cut resistance. We are both very happy with the tires. Both vehicles are relatively light which I presume is why we get such longevity from the tires. Have C rated KO2s 285s on a JKUR same results, will replace with E when needed.
