Troubleshooting Why Left Rear Tire Has A Bald Tread And The Other Tires Are Fine

Question:

We’ve got a two axle leaf spring setup and noticed the left rear tire has worn the tread bald. No other tire has any excessive wear. Getting new tires, but wondering what could cause this?

There are a few different reasons why your tire tread was bald and your other tires are fine. One option is that you could have a bent or damaged spindle on the trailer. Another option could be that unevenly loading your trailer and putting more weight on the bald tire side. The stem valve could be bad which is not allowing it to hold its full pressure. An under inflated tire will wear a lot faster especially at the outside edges of the treads surface. An over-inflated tire will wear more in the middle of the tread.

Special trailer tires whether it's a bias or radial tire should always be inflated to the maximum cold psi pressure shown on the tire's sidewall.

Another problem could be that the brakes are over adjusted and are locking up.

For a replacement tire The Castle Rock ST205/75R14 Radial Trailer Tire # LHCK201 is a good choice. The tire has a load rang C and has a ply rating of 6, and has a maximum load of 1,760 pounds at 50 psi. The tire has a maximum speed rating of 75 mph and has a 5 year warranty.
