Trailer Tire wear

[JCher]

On May 1st I purchased a new 2011 travel trailer. I have taken three trips for a total of approximately 600 miles. I noticed last week that all four tires are showing abnormal wear on the inner and outer edges. The trailer came with ST205/75R14C tires. The MFG. date is 26-10. I inflate them to 50 PSI which is the recommended pressure on the sidewalls. I have used several different tire pressure gauges to cross check the gauges and tire pressures. The trailer has only been towed on pavement and not above 65 mph. The trailer is currently at the dealer for some warranty work and when I mentioned the tire issue the service writer said that he did not think the tires would be a warranty item. He said something about the way the trailer is turned may be causing the wear. My question is are the tires a warrant item? Also should the tires with only 600 miles be wearing the way I described? I stopped by a local tire store and was told the tires should be replaced. I understand the tire store is in the business of selling tires but will the trailer be safe to tow without new tires.

If your tires are showing wear at 600 miles, and you aren't overloaded, you probably have an alignment problem, which your dealer should address. Your tires are covered either by the manufacturer or distributor for 3 to 4 years for failures due to defects, but not alignment problems. Good luck.

I have the same problem on my side x side utility trailer. Was told it was because of cheap tires,carrying max load,or close,,,sidewalls give too much,making it look under inflated..but it isn't..

Classic symptom of underinflation. Is that 50PSI as listed on the tire sidewalls?
