I have always been a fan of Kumho M/Ts over the past few years. Every truck I have lifted and had 22's or 24's on (Which is 6) has had a set or two on them.... I recently bought a new set and do not know what Kumho has done or changed, but this is the last time I EVER BUY THEM!!!! I bought 38x14x24s back on Feb. 24th and never in my life have I ever had such a crappy riding, non balancing, fast wearing tire in all the previous sets as these. I have spent 420 bucks since I bought them trying to get the shakes out of them and finally had a buddy who works for a retread facility check them out to find 3 of them are out of round..... I called the company I bought them from who are sending me a new set at no charge but 37s since they dont have 38s which is fine with me... My warning to you guys who just recently bought them is that if you can not get them to balance and still have shakes at speeds have someone check them to see if they are true.... I will update this tread next week when the 37s get here. We will be running them on the machine before they go on my truck to see if they are true or not... If they arent Nitto M/Ts or Toyo M/Ts here I come!!!
