Hey Chris, remember when I posted the statements from carlisle about their st tire construction? And you suggested it was marketing malarkey?
Tim Fry, senior development engineer with Goodyear Tire & Rubber Company stated, “The major difference is reflected in the polyester cords used in ST tires. These cords are bigger than they would be for a comparable P or LT tire. Typically, the steel wire also has a larger diameter or greater tensile strength to meet the additional load requirements. Because of the heavier construction for an equal volume of air space, an ST tire is designated to carry more load than a P or LT tire.”
It's almost word for word.
Sounds really great! BUT why do they fail at such a high rate? Most ST235/80R16E's weigh in at 35 pounds, while LT235/85R16E's weigh from 41 to 57 or 58 pound for the steel carcass ones. I am convienced that a RIB tread steel carcass tire is the best for trailer use, if one wants to see America!
Up 6k axles XPS RIBS or R250s
Up to 6750 G614s. Or same as below
7k and above 17.5 rim and commercial 215/75R17.5s.
All of these options should be good for 5-7 years.
