Why do european cars use lug bolts? (2024)

What is the point of lug bolts?

While a lug nut screws onto a threaded wheel stud that is attached to the hub, a lug bolt eliminates the need for a wheel stud. Its design allows the wheel and the brake rotor to be directly attached to the hub. Lug bolts are more often seen on European cars, appearing on brands such as Audi, BMW and Volkswagen.

Are wheel studs better than bolts?

Well, the wheel stud wins by a large margin.

Stud and nuts for the win, in my humble opinion.

Why do trucks have so many lug nuts?
