change to LT tires
I went to a Firestone, similar to the Bridgestone's mentioned. Had Marathon's originally and they were OK, lost a couple but they were a bit old, no damage. Last one I lost took out a fender flare, etc. so went to all Firestones at the suggestion of my friends at Western Tire in Burbank (HIGHLY recommend these guys, been buying tires from them for 35 years).
The following info is from the linked site.
Trailer Tire FactsWhy Use An "ST" Tire
"ST" tires feature materials and construction to meet the higher load requirements and demands of trailering.
The polyester cords are bigger than they would be for a comparable "P" or "LT" tire.
The steel cords have a larger diameter and greater tensile strength to meet the additional load requirements.
"ST" tire rubber compounds contain more chemicals to resist weather and ozone cracking.
Also
If a tire fails on a tandem axle trailer, you should replace both tires on that side. The remaining tire is likely to have been subjected to excessive loading.
