Sailun Tire Failure

I don't mean to sound like I'm bashing the XPS/Rib. In fact I ran them for many years. My point was that if you ask Michelin (as I have done several times) if Michelin will warranty the XPS/Rib when used in a trailer application. The answer I always get is the XPS/Rib is an LT tire and not suited for trailer use - Michelin will not warranty the XPS/Rib when used on a trailer.

Yours and others problem with Michelin is you may have backed them into the liability corner by the way you ask your tire question. What Michelin says has been going on for several years now so we know it all depends on how the question is phrased.
Lots of emails from Michelin floating around as this one. Notice the question doesn't back them into the liability corner such as asking does the Ribs replace a Load E ST tire/others. Sure we know a ST E has 3400-3600 lbs capacity so the LT E Ribs at 3042 lbs is not a replacement for the higher capacity tire.

In regards to the email you sent stating: Question..
I have a 2006 Montana 5th wheel Trailer that has two 6,000 lb Dexter axles and 4 deluxe aluminum Rims each rated at 3,042 lbs. I would like to install your Michelin XPS® Rib™ LT235/85 R16/E's on this 5th wheel. Will the tires be fully waranteed in this application?

Answer..--------
We appreciate your request for information regarding the Michelin XPS Rib. The XPS Rib, size LT235/85R16/E, part number 13080 would be a good fitment for your 5th wheel. The tire carries 3042Lbs at 80-psi max pressure. For best pressure recommendation, run at maximum pressure until you can weigh your axles either call or reply to this email for a pressure recommendation.
It is a good application, so there are no warranty issues. Your tires are covered under applicable warranty.
We appreciate your business and thank you for choosing Michelin**
