Odd Travel Trailer Tire Wear

by Tracy
(Palmdale CA)

I own a 2008 Fleetwood Mallard 180CK Travel Trailer, the tires on it are wearing odd to me

The tires are wearing on the inside and outside edges faster than the middle of the tread ........

Is this due to the axles being out of align or is it simply air pressure ....... I'm running them at 50 PSI as indicated on the side of the coach.

Thank you
Tracy

ANSWER: Hi Tracy, thanks for submitting your question on our Ask An RV Question Page.

The most common cause of the tire wear that you are describing is under-inflated tires. Even though you state that you are filling your tires to the recommended PSI that is written on the placard on your coach, you may actually be under-inflating your tires.

Unless you have owned this travel trailer since it was new, you cannot be sure if the previous owner has replaced the tires with a different brand of tire that requires a different air pressure to carry your trailer's weight. To be safe I would go to the website of the company that manufactures your tire and see what their recommendations are for PSI based on your Travel Trailers loaded weight.

If you are depending on an air pressure gauge at a service station to give you an accurate reading you may also be under-inflating the tires as these gauges are not always accurate. I would strongly suggest that you purchase a good quality tire pressure gauge to insure that you are getting proper air pressure readings.


Another more serious cause of the tire wear you are seeing could be a result of you exceeding the weight limitations of your Travel Trailer. Even a properly inflated tire will have the wear pattern you have described if it is carrying more weight than it is designed to carry.

When your trailer is fully loaded, you should take it to a weigh station and have it weighed and once you have its actual weight you need to compare it to the maximum weight rating recommended by the manufacturer.

I hope that this information has been helpful.
