I had a couple of sets of 35" KO's on an F350 a few years ago. Quiet, smooth ride, good tread life. They are good in rain, sand and mud. I just replaced a set of 31's on my jeep this weekend. I don't drive the jeep much so the old set purchased in 2002 only had 10000 miles. They were dry rotted and cracked and leaking air, so I drove down to Discount where I bought them 11 years ago. The salesman refused to work on them because they were so old, can't really blame him. So because I had a lifetime replacement warranty he swapped out the two leakers for free and discounted the other two by $30 each. I drove out with a new set for $350!
