Costco Michelin Ribs update
Was able to talk to the local Costco Tire Store manager today to try to get clarification on what the warrantee would be on the Michelin Ribs 235/85 R16 tires for a 5th wheel. No mileage guarantee, No...

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.
Chris
What makes you think LT & medium duty tires will have a longer life expectancy on the RV trailer axles?
The GY G614 and Michelin 17.5” LRJ tires used as OEM have experienced tread separations under the 4 year mark.
Who knows about the Michelin & Bridgestone tires you have mentioned. They are not trailer tires and are not used as OEM. Who would ever post an unkind word about them on this forum? Remember, the DOT describes the LT tire “as a tire designated by its manufacturer as primarily intended for use on lightweight trucks or multipurpose passenger vehicles.”

I respectively ask again! Please take your long running feud to another topic and place. You both have good points but they are not contributing to this thread!
