315/80 vs 12R - was Overweight

[Pete Masterson]

In my research on the Toyo lawsuit, it appears that the RV manufacturer selected tires that were insufficient to carry the weight. Toyo no longer offers OEM tires to RV manufacturers.

Keep in mind that manufacturers select tire vendors based on competitive bidding -- and there may be very few bidders in the RV market. The tire manufacturers understand that vehicle owners are somewhat more likely to buy replacement tires from the same manufacturer if they were satisfied with the OEM tires.

Also, it is important to understand that OEM tires may have different specifications than tires on the replacement market. (Although the tire volume required by RV manufacturers may not justify unique specifications during manufacturing.)

Here is something to consider: Go to any large RV dealer ( I think there are still one or two in business). Look at all the Class A's. You will see 2 brands. Goodyear and Michelin. If an RV mfr. could save 6x$200 per unit they would jump at the chance. Why do you not see Sumitomos or Double Coin on the units? The only RV mfr. I know of that tried another brand was National/ CC and that ended up in a law suit (Toyo). Tiffin was installing GoodYears and had lots of troubles. Bob Tiffin paid for Michelins to be installed at his expense. If a customer wants GoodYears on his Tiffin they will NOT install them at the factory.
