You can minimize your chances of getting a flat tire by taking a few minutes to ensure proper inflation. Inspect tires when they are cool for cracks and spider webbing that occur when rubber tires stay in one place for extended periods of time. Carry at least one spare tire assembly, and only replace radial with radial, bias ply with bias ply. Flat tire eliminators such as Slime have proven their worth over the years for fixing flat tires caused by small punctures.

Improper bearing maintenance and lubrication account for most highway trailer breakdowns. At most ramps, boaters are forced to dunk their axle wheels and bearings in the water in order to unload the boat. When a warm hub is submerged in cold water, the air inside the hub contracts and draws water in through the best of seals. Once parked, the fresh- or saltwater will settle at the lowest point in the hub. This is where corrosion and rust begin. The next time the trailer is moved, the bad spot on the bearing may cause excessive heat and eventually total bearing failure. In the worst case scenario, heat can be intense enough to sever the axle and wheel.

When checking rear bearings (axle side) always replace the seal with a new one to ensure a good tight seal.
