I've been reading some of the past posts for 'ST' tires versus 'LT' tires and I'm a bit confused. If what I'm reading is correct, then the 'ST' tires have a better reinforced sidewall to handle the flexing that occurs when the trailer is being towed and maneuvered and 'LT' tires don't have that. Is that correct? I only run BFG 'AT' on my trucks. When I can get 80,000 miles out of a tire with no flats or blow outs, that's very good value in my opinion. That being said…, I don't see anyone advocating running 'AT' tires on a trailer. In regards to the personal opinions that I have read of past tire posts, I think so long as I purchase an 'E' rated tire (8 or 10 ply) whether it be Carlisle or Maxiss I will probably get good performance out of either. I will do some further research on the Duravis & Michelin. I'm leaning towards the Maxiss but the only downside I see so far is availability. If most places don't keep it in stock that could be problematic in the event of a tire mishap and having to special order a replacement tire. I'll keep reading and thanks for the input thus far.
