Why do cars have different PCDS?

As cars become faster and faster, the potential forces on the wheels will increase. Manufactures don’t want to spend the money on exotic materials for wheel strength, so instead have moved to larger PCD’s to account for any increased forces the wheels might see.

Why do wheels have 2 bolt patterns?

Dual bolt patterns have an additional set of bolt holes, enabling the wheel to accept two different bolt patterns. For example, a wheel with a 5-100/114.3 millimeter bolt pattern has ten total bolt holes. It can accommodate both the 5-100 millimeter bolt pattern, and the 5-114.3 millimeter bolt pattern.

What does PCD stand for on car wheels?

On any trailer wheel assembly or rim, the Pitch Circle Diameter (PCD) is the diameter of the circle which passes through the centre of all the wheel bolts or wheel rim holes. The center of every bolt hole lies along the edge of the pitch circle and are evenly spaced.

What does PCD stand for in cars?

What is universal bolt pattern?

Uni-Lug wheels are a type of wheel that can fit more than one bolt pattern. Other types of wheels that fit more than one bolt pattern are called “Dual Pattern” or “Multi-Lug” wheels.

Which way do Lugnuts go on?

To complete this task, place your car in park (or in gear should your vehicle be equipped with a manual transmission), and using a lug wrench, loosen the lug nuts that are holding the wheel in place. To loosen the lug nuts, turn them in a counter-clockwise direction. Remember, righty tighty, lefty loosey.

Why do some cars use 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.
