Why do semi trucks have spikes?

Is it to be scary? I heard somewhere it’s to prevent rainwater from sticking to the bolts which sounds like BS.

They’re completely decorative. They’re just aluminized plastic; they’re friction-fit over the lug nuts. (They won’t gouge up your car if you get sideswiped; the catastrophic damage your car receives in that case will come from other causes.)

It’s so you can easily see if a wheel nut has moved and needs to be tightened up. The spike is just a visual indicator of the nut position.

They are a signal to the lot lizards that this driver is lacking a penis, so move on. The same as those chrome testicles that people put on their Ram 1500 pickup dangling off the trailer hitch.
