why do tractor trailers have spikes on their wheels

Tractor-trailers, also known as big rigs or semi-trucks, are an essential component of commercial transportation. These large vehicles transport goods across vast distances on highways, making long journeys easier and more efficient. As we travel alongside them on the highway, we often notice that some of these vehicles have spikes on their wheels. These spikes are added for a variety of reasons, and this article will explore why tractor trailers have spikes on their wheels.

Increased Traction

One of the reasons why tractor trailers have spikes on their wheels is to increase traction on icy or slippery roads. The spikes, also known as studs, are designed to dig into the ice or snow on the road, providing the trailer with additional grip. This is especially important in areas with severe weather conditions, where drivers need to maintain control of their vehicles to avoid accidents. The studs on the trailer tires provide drivers with confidence and allow them to travel safely.

Improved Braking

Another reason why tractor trailers have spikes on their wheels is to improve braking performance. The spikes help the tires grip the road surface better, allowing drivers to apply the brakes more forcefully without fearing a loss of control. On wet or slippery roads, braking can be a significant challenge for drivers, but the spikes on the wheels of the trailer can help increase stopping distances and prevent collisions.

Increased Durability

Studded tires are also more durable than regular tires, which can be important for big rigs that travel long distances. The wear and tear on the tires can cause them to lose tread over time, and this can significantly reduce their performance. However, studs can increase the lifespan of a tire by helping it resist damage and wear. As a result, this can help save money on tire replacements for trucking companies.

Conclusion

In summary, the spikes on the wheels of tractor trailers provide many benefits, including increased traction, improved braking, and increased durability. These features are essential for truckers who regularly travel long distances on highways, particularly in challenging weather conditions. So, the next time you see a big rig with spikes on its wheels, you can now understand why they are there.
