I sent an email to Michelin for a response regarding using Michelin XPS ribs on my 5th wheel. Here is the question and their response:

Thank you for your email. We welcome the opportunity to serve you.

Due to recent high email volume and some technical issues that we have experienced, please accept our apology for the delay in this response. Your interest in Michelin is certainly appreciated.
In regards to the email you sent stating:
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.

PS: It's important that you get all the safety-related materials that come with the purchase of new Michelin passenger and light truck tires. If you did not receive a warranty book, you can download one at www.michelin.com/warranty/. If you did not register your tires, please take a moment to do so at www.michelin.com. Registering your tires is easy and takes just a minute.

This letter has been referenced before. It is as incorrect now as it was then.

The initial letter writer did not provide the correct information. The only correct information is found on the vehicle's certification label.

The reply letter is in violation of the very warranty they profess will support such fitment.

Here are the disclaimer items found under the heading; WHAT IS NOT COVERED starting on page #2 of the Michelin warranty.

1. Bullet #3; Misapplication

2. Bullet # 10; Use of MICHELIN tires that is inconsistent with the safety and/or maintenance information provided in your owner’s manual.

Here is an excerpt from the 2013 Keystone RV Trailer Owner's manual (generic). Page #18 of the Keystone reference.

1. To maintain tire safety, purchase new tires that are the same size as the vehicle’s original tires or another size recommended by the manufacturer.
