What are the Spikes on Semi-Trucks for – What’s the Real Purpose?

Benefits of spikes

Most likely you have seen them in the movies, those big rigs with giant metal teeth surrounding their wheels. While they may look dramatic, the spikes serve an important purpose.

Let’s find out what those spikes are for and why they’re so important!

What are the Spikes on Truck Tires for?

If you ever wondered why semi-trucks have spikes on their wheels? It might seem like a strange addition, but there’s actually a good reason.

Some of them include:

1- Protection of Lug Nuts

Wheel spikes are typically meant to keep the lug nuts from corroding, rusting, or becoming filthy. This is especially useful when driving on rough terrain or in bad weather conditions.

They also serve as a deterrent since they appear to be quite hazardous and similar to films.

The metal teeth keep the lug nuts in place while driving and also make it more difficult for thieves to steal them.

2- Warning Sign

The other function of wheel spikes is to serve as a warning sign – since these spiked are immediately noticeable.

For instance, when a motorist gets too close to a commercial truck, the spikes on the wheels can serve as a reminder to keep their distance.

In some cases, the spikes may even cause damage to the vehicle that gets too close, depending on the size and sharpness of the spikes.

3- Clearing Snow and Ice

In some cases, the teeth on the spikes are also used to help clear snow and ice from the truck’s wheels.

This can be especially useful in winter weather conditions when roadways are covered in snow and ice.

The spikes can help to break up the snow and ice, making it easier for the truck to get traction and move forward.

4- Good Appearance

Let’s be honest, the spikes look pretty badass. They can also make a truck look more intimidating on the road.

In some cases, the wheel spikes are purely for decoration and are not meant to serve any actual purpose.

This is usually seen in custom or modified trucks, where the owner has added the spikes for a more aggressive or unique look.

And that’s the reason there are a few different types of wheel spikes that you may encounter.

While some are long and pointy, others are blue and green and they may have a glossy or matte finish.

Then there are also the blue bullet-shaped wheel spikes (much like castles) and a few others that are shaped like drill bits and even gold rods.

However, they’re all meant to let you express yourself in the most effective manner possible!

Are Wheel Spikes Dangerous and Legal to Put On?

Most wheel spikes are no longer than four or five inches long, and they don’t extend past your fender, rock slider, running guard, or bumper. Wheel spikes are therefore not dangerous.

The legality of wheel spikes however varies from state to state, so it’s important to check the laws in your area before driving around with them.

In some states, like California, it is illegal to have any type of metal protrusions on your tires.

However, in other states, like Texas, there are no laws against them.

So, if you’re ever unsure, it’s always best to err on the side of caution and avoid driving with them.

Final Thoughts

While many people think that the spikes are there to puncture other vehicles, this is not the case. In fact, they are designed to avoid causing damage.

While wheel spikes may look cool, they can also be quite dangerous to other vehicles (and even people) – if they’re not used properly.

So, if you want to put them on your semis or 18-wheelers, just be sure to check the laws in your state first.

Otherwise, you may find yourself with a hefty fine!
