St tires vs LT tires

djgarcia, The primary difference is "beefer" cording in the sidewalls of the ST tires, whether it be polyester or steel. Trailer tires, because of their use, experience much more "side loading" during the sharp turn of the trailer. The stiffer sidewalls reduce the probability of the tire "rolling" off of the bead during an extremely sharp turn. If you look at commercial truck tires... You have "steer" tires, drive or traction tires, and trailer tires. Granted, these are a more "specialized" service, but the logic is the same! memtb


If you do a Google search, you can get a better explanation than I am capable of providing!!

Also... In our world of lawyers and litigation, if you use an LT tire in place of an ST tire and a tire failure caused a major (injuries or fatalities) auto accident.... you "may" be held liable in court!!

Sorry to say, while the tread pattern may be different in Commercial semi tires the carcass are all the same. Steer, driver or trailer are all the same carcass construction,.
Steer tires CAN'T be retreads they need to be new. Once the tread is worn these become capped and used as either trailer or driver tires. Commercial truck tires will likely be retreaded three to six times before they are dumped.
