Red Seal Transport Trailer Technician Practice Exam

The lifespan of trailer tires is significantly influenced by load, tire pressure, speed, and road conditions. Each of these factors plays a crucial role in how tires perform and wear over time.

Load refers to the weight the tires need to support; exceeding the recommended load can lead to excessive heat buildup, which accelerates wear and can even result in a blowout. Proper tire pressure is equally important because under-inflated tires can cause increased rolling resistance, overheating, and faster wear, while over-inflation can lead to uneven tread wear and a harsher ride.

Speed is another critical factor, as driving at high speeds increases the temperature within the tire, which can lead to premature degradation of the rubber compounds. Lastly, road conditions—such as whether the surface is rough or smooth, wet or dry—also affect how quickly tires wear down. Rough road surfaces and poor weather can increase the strain on tires, contributing to quicker tread loss.

Overall, monitoring these four factors can help extend the life of trailer tires and ensure safer operation on the road.
