Can You Put a Trailer Tire on a Truck Wheel?

The question of whether to use trailer tires on a truck can be a bit complex. While it might seem logical if the tire and wheel diameters match, there are several important considerations to keep in mind. This article aims to provide detailed insights into the suitability of trailer tires for truck applications and their performance in various conditions.

Understanding Trailer Tires and Their Limitations

Trailer tires are designed specifically for the demands of towing. They are engineered to handle the low stresses typically encountered when the tires are in a trailer position. In these conditions, trailer tires need to support the weight of the trailer and simply roll down the road, rarely experiencing the intense cornering forces that drive and steer tires endure.

As a result, trailer tires are not designed to handle the more aggressive use often associated with loading and unloading a truck. These tires may not provide adequate load-carrying capacity or performance for a truck, and their tread patterns and construction may not be suitable for the harsher operating conditions outside of a trailer setup.

Usage in Inclement Weather

While trailer tires are generally less reliable in inclement weather conditions, they can still be used in both the drive and steer positions on a truck. However, it is important to note that the longevity and reliability of trailer tires in these positions can be significantly reduced.

Tire Mounting and Compatibility

Assuming the trailer tire fits the diameter of the truck wheel, it is technically possible to mount a trailer tire on a truck or tractor. However, this should be done with the understanding that trailer tires are not optimized for the steering and driving demands of trucks.

In terms of durability, trailer tires designed for trailer use are optimized for weight support and straight-line travel. While they can still be used with proper air pressure, they are likely to wear much faster and could reach the steel belts in as little as 40,000 to 50,000 miles compared to the typical 150,000 miles for trailer tires.

Typical Tread Depths for Different Positions

To better understand the stresses each tire position encounters, here are typical factory tread depths for tires designed for steer, drive, and trailer positions:

Steer — 19/32″ to 22/32″ Drive — 26/32″ to 32/32″, with some drive tires like the Bridgestone M726 having a full inch of tread Trailer — 15/32″ to 18/32″

These tread depths align with the stress the tire manufacturers expect each tire to endure in its respective position, highlighting the difference in durability and performance requirements for trailer, steer, and drive tires.

Conclusion

In summary, while it might be tempting to use trailer tires on a truck, it is generally not recommended due to the specialized design and intended use of these tires. Opting for tires specifically designed for trucks will ensure optimal safety and performance. However, if trailer tires must be used for some reason, be prepared for a shorter lifespan and potential performance issues.
