Don't take my word for it, don't take "Me Again's" word for it. make up your own mind. Go to any commercial tire shop that sells both ST tires and LT tires and compare head to head the typical Carlisle, Towmaster, Load Star what have you to the comparable sized Duravis, XPS Rib, Commercial TA and several other quality center rib, solid shoulder LT's. The difference is amazing and undeniable. Only after you have done a side by side comparison then make your own decision which tire you want your safety and confidence riding on, not to mention your multiple 10's of thousands of dollar investment riding on.
Do you really want them riding on manufacturer "Delivery" tires whose only requirement is they don't fail during delivery from the plant to the dealer.
They put the exact same lowest cost bidder delivery tires on park model trailers that never move once delivered as they do fifthwheel's that purchaser's intend to tow thousands of miles per year.
It's your money, your safety, your enjoyment, your confidence, your trailer, not mine.
Experience and research made my mind up.
Just say no to "Delivery tires"
