I put this on a 3 car trailer (26K lbs) They are holding very well and wear excellent. I got the load range H. I cannot seem to find them anymore. They hold 110psi, so they will haul some heavy weight. Good so far. Buying more

I've only put approximately 15,000 miles on them so far (On our 10k lb flatbed trailer) but they are wearing like iron. Very happy so far.

Get technical:

The Trailer King Ultra STR is purpose-built for high-capacity trailers in regional or long-haul service.



Features & Benefits

  • All-steel belted construction boosts strength and durability
  • Cross rib sipes and four circumferential ribs improve wet and dry traction by forcing water out of the tire and by creating additional biting edges
  • Stone ejectors force rocks and debris out of the tire to protect the casing from damage
  • 12/32" tread depth
  • 4000 lb weight capacity per tire - requires special high-load-capacity rims
  • Trailer tire -- not suitable for vehicle use
