Carlisle Tires
34'Heartland 5th wheel. Came with Tow max tire. 5 years of good use . Probably around 10,000 miles. Noticed a low tire, 65 lbs, and brought it back up to 80. I should have stopped by a tire store...

Most of the problems have been the ST tires on large travel trailers and fifth wheels weighing over 14K lbs.
There are G-rated, ST tires like the Gladiator and Hartland (Discount Tire, Gladiator housebrand) that have a 14-ply rating, all-steel carcass, an L-N speed (75-87 MPH) rating, and weigh 60+ lbs. (typically 20-25 lbs more than the same size E-rated tire). To my knowledge, there haven't been any issues with these ST tires, even on the very heaviest rigs.
