If you accidentally bump or scrape something, the spikes can help offset any major damage (like the actual Rim and bolts). This way only a minor cosmetic thats cheap to replace is broken.
The biggest thing is they are more of a cool truck decoration. Their popularity is partly due to the price and ease of installation. They also really make a difference for the truck lovers out there.
Just a note, these spikes break off very easily. No worries about a Mad Max rig tearing into your car on the highway. Even if they might give that appearance.

Initially they were plain, but truck drivers love customizing their trucks.
