The Access Tools Wheel Bullet 3-Pack is designed for European vehicles that do not have the wheel studs that American vehicles have on which to mount a wheel, to make performing wheel service on European vehicles easier. Two wheel bullets are needed per wheel to properly hang and align the bolt holes. the 3-pack includes a 12mm by 1.5mm size, a 14mm by 1.25mm size and a 14mm by 1.5mm size. According to the company, this covers almost every European vehicle on the road, including VW, Audi, Porsche, Mercedes, BMW, Mini and Volvo. The Wheel Bullets function like guide pins or wheel hangers, allowing the wheel to be removed and installed easily.
