Troubleshooting Outside Tread Wear on Trailer Tires

Question:

I have a 6x10 trailers plus enclosed trailer and the outside edge of the tires wears out in 2000 miles. The tires are inflated to 65psi. Trailer is rated for 3000 lbs and I run with 600 to 700 lbs of motorcycles. It has dexter axles with 3 degree bend. Trailers plus said I don’t have enough weight in it and there is no fix. Weight is distributed evenly, trailer sits flat while towing. I need to fix this.

The information that you received is correct in that if you are getting outside wear on your tires on both sides simultaneously it indicates that you don't have enough weight in your trailer.

For your situation I recommend using Goodyear tires. So far Goodyear is the only trailer tire company that I know of who has different weight ratings for different psi ratings for their tires (as of July 2019). If you are using 205/75R15 size tires then you want the Endurance # 724861519. This has a load range D (2,150 lbs at 65 psi) but if your trailer only weighs in at 3,000 lbs you can put 40 psi in the tires for a weight rating of 1,610 lbs each (total of 3,220 lbs), according to the attached chart, which should help your tires to wear evenly.

Aside from that your best bet is to have some extra weight in your trailer like sand bags or cinder blocks to help increase the weight of your trailer. You may need to have a trial-and-error basis to see what works best for your application.

If you have a different tire size please let me know what it is and I can see if we have a Goodyear tire in that size or you can check out our linked selection for the appropriate tire size.

A buddy said to just buy some used 15” car tires that have steel belts. I may try that first and under inflate them .

You can try that if you like but we don't recommend using car tires for trailer purposes as vehicle tires have more flex in the sidewall to help with ride quality while trailer tires have stiffer sidewalls to help accommodate their loads.

The Goodyear tires actually use double steel belt overlays to help prevent tread separation. Goodyear basically brought their experience with passenger car tires and applied some of that to trailer tires for a great combination of features which you can find listed on the product page.
