I have a 2004 Keystone Cougar 24.5 foot 5th wheel, purchased new. We have less than 10,000 miles on two sets of new tires. The two right side tires both shredded (approximately 4 hours a part) when we were returning home to So Cal from Utah. At the time, we probably had less than 2,000 miles use. On another trip to Baja, a tire blew on the right and tore up the side of the trailer and caused damage to the gas line underneath. We replaced all four tires with brand new heavy duty tires.

Last week we took a 300-mile round trip and the replacement tire on the right side once again shredded causing more body damage.

The problem is only occurring on the right side. The alignment has been checked and appears to be OK. Has anyone experienced this situation and do you have any input?

We love the trailer but are getting frustrated.

I can only think of two things at this time. Under pressured tires or driving to fast, ( 65 mph max on ST tires ) on hot roads.

Just taking a guess, but could your right trailer brakes be grabbing, causing the tires to heat up. I'd have the brakes checked.

Or....are you overloaded and causing excessive heat? Leaky valve stem causing low pressure while under tow?

Replace valve stems, check brakes....after doing some driving. Get your trailer weighed.

Good luck!

I am not sure what your problem might be. But we have a 2004 Keystone Laredo that has Al-Ko axels on it, well back in 04 my camper was eating tires at an alarming rate. after reading about misaligned axels from al-ko on THIS Fourm, I called them. after telling them my axel tag #'s it turns out we had bad axels that were welded at the wrong angle. Al-Ko promtly sent out new axels to my dealer and reinbursed us for four new tires plus all parts and labor.

Alko axles are your problem. Mine were replaced along with 4 new tires under warranty. Call Keystone and they will give you a name and phone numbet to give to your dealer for warranty repair.

Perhaps the right side has more weight?

Our tires weren't blowing but they were wearing on the inside edge. After going a couple of rounds with Mike Thompsons and ALKO they replaced our axles too, at no cost to us.

I understand that the axle tubes were under-rated for our trailer. Since the replacement we've had no furher wear issues.

I would strongly suggest getting the trailer weighed by wheel position to insure your not too heavy on one side. I would have your air gauge checked for accuracy, and then make sure your running those tires at the maximum air pressure. Shredding tires is norrmally underinflated, or overload, or a combination of both.

Have you actually weighed your trailer to see what load you are carrying on the tires?
What size tire are we talking about and what weight is the tire rated for?
Nobody can give you an answer until the above two questions have been answered.
You might be using a ST rated tire when you should have a LT rated tire. The difference being the ST tire is only rated for 65 MPH max and the LT tire is rated for a speed that you would never pull the trailer. Most of the newer and heavier trailers are coming from the factory with LT rated tires.
