Key item features

  • Trailer Specific: Designed exclusively for trailer applications like utility, RV, boat, and horse trailers, not for drive or steering axles.
  • Robust Construction: Features a reinforced internal structure with a 12-ply rating, capable of handling substantial weight and pressure.
  • Heat Dissipation: Utilizes a special heat-dissipating tread design and durable compound to minimize heat build-up during long highway trips, reducing blowout risk.
  • Enhanced Stability: Tread pattern with solid center ribs and squared-off shoulders ensures straight tracking, prevents trailer sway, and improves lateral stability.
  • Weather Resistance: Circumferential grooves channel water for wet grip, and UV/ozone resistant compounds resist weather cracking, prolonging tire life during storage.
  • Load Capacity: High load rating, including 121/117M F, supports heavy trailer loads with ease, ideal for large RVs and equipment hauling.

I upgraded my 32 foot camper to these 12 ply tires from the factory 10 ply. I just completed a 5000 mile trip with them and absolutely nothing but praise. Smoother, quieter ride. Less bounce and more control of the trailer. I had them mounted with a tire conditioner and balancing gel inside as well for dynamic balancing and temperature control. Will definitely buy again.

tires held up well on our trip, I would recommend you get the 14 ply if you can, it is a lot better tire
