Reading so much about the "China Bomb", which i have on my rig, they got less than 500 miles on them, gonna make sure the PSI is always correct, load balanced and not over and keep my speed at or below 65 mph, put trust in my TireMinder TPMS and then roll with them for the year..Then maybe a Christmas present from the DW for a new set of Carlisle or Maxxis for next summer..
