For many, driving next to a massive 18-wheeler can be a bit unsettling—especially when you spot those intimidating metal spikes covering the truck's wheels. While these decorations may seem a little threatening, their purpose isn’t to cause fear.
As Big Rig Pros highlights, the main function of the spikes is to protect a wheel’s lug nuts, which secure the tires to the axles. Given the extensive distance that 18-wheelers travel, it’s easy to see why their lug nuts endure more wear and tear than those on other vehicles. The spikes safeguard the lug nuts from dirt and moisture, preventing rust and ensuring they stay tight.
Though these covers are tough enough for the job, they're not always as indestructible as they appear. Many are made of plastic designed to resemble chrome. As for why so many truckers prefer pointed covers over flat ones, it’s often a matter of personal style. After spending countless hours on the road, it’s only natural that drivers would want to customize their rigs. As Big Rig Pros puts it, it’s similar to how office workers decorate their cubicles.

If those eye-catching spikes on the road remind you to keep a safe distance from an 18-wheeler, then they’re doing their job. Truck drivers have large blind spots along the sides (and front and back) of their rigs, making accidents more likely when vehicles wander into these so-called ‘no-zones.’ In this way, the spikes are not only protecting the lug nuts but also helping to safeguard you, the truck driver, and everyone else on the road.
