Troubleshooting Odd Tire Wear on Passenger Tires for 1988 Travel Trailer

There are a variety of possible reasons that the passenger side tires are wearing the way they are on your 1988 Travel Trailer. Starting with the simple fixes, I recommend making sure you are not overloading the axle and tires on your trailer. Check to ensure that the combined load rating for your tires meets or exceeds the loaded weight of your trailer. Do the same thing for the trailer's axle capacity.

Also verify that all of your trailer tires are always inflated to their maximum psi as listed on the sidewall. An underinflated tire can specifically lead to wear on the outside edges of the tread. An over-inflated tire will lead to wear more toward the center of the thread.

If everything checks out fine, then there is likely some kind of issue with the axle as it relates to the alignment. To determine if the axle is not aligned properly, measure from a single point on the trailer (dead center of the coupler) back to the center of the axle on each side to see if they are the same or different distances. If they are different, you may be able to make some adjustments with the suspension to straighten it out. You can also use a straightedge (such as a 2x4 or long piece of steel) and hold it up against the the bulge of your trailer tires. All of the bulges of the tires should make contact with the straightedge. If there is a gap of more than 1/8 inch between one tire and the straightedge, this indicates an alignment issue.

If this still does not help, then there may be a problem with the axle itself or the spindles that would call for a replacement. I have attached a link that will take you to our available selection of trailer axles so you can see if we have one that will work on your trailer.
