Is the PCD marked on a wheel?

PCD (Pitch Circle Diameter)

Is the diameter of the circle formed by the holes on your wheels in millimeters. They are usually written in the hundred or near the hundred beside the number of holes such as: 4×100, 4×120.

Is PCD written on rim?

On any trailer wheel assembly or rim, the 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.

Is PCD the same as bolt pattern?

Definition & Description. The bolt pattern of a wheel is the layout of the mounting holes. A wheel's bolt pattern can also be called its "Bolt Circle" or "Pitch Circle Diameter (PCD)". Bolt pattern is expressed as the number of lugs by the diameter of the imaginary circle formed by the center of the lugs.

What is PCD in alloy wheels?

How do I find my PCD flange?

What does 5x120 bolt pattern mean?

The 5x120 Bolt Pattern or Pitch Circle Diameter (PCD) is made up of the stud count (5) and the bolt circle measurement (120), the notional circle determined by the center position of the studs. The 5x120 bolt pattern is common to Acura, BMW, BMW Alpina, BYD, Bentley, Buick and Cadillac vehicles.

What does tire PCD mean?

The most important element of wheel manufacture is the bolt pattern or 'PCD' (pitch circle diameter) of the wheel.

Do 5 lug universal rims fit all cars?

No, there is no such thing as a universal wheel. Numerous factors come into play when deciding what wheels can go on your vehicle. Two of the most critical factors are the wheel's diameter and width. Every car will have a range of wheel diameter sizes of several inches that will securely and adequately fit.

Does the bolt pattern have to be exact?

The bolt pattern or bolt circle is vehicle-specific and cannot be changed. It must be the same as the wheel.

What does ET mean on rims?

Rim inner surface

In practice, the ET-value is the number in millimetres that the centre line of the wheel deviates from the mounting surface (on the wheel hub). As a rule of thumb: the higher the ET, the more a wheel is positioned inwards; the lower the ET, the more a wheel protrudes outwards.

What does 6j mean on wheels?

J rim contour has 17.5 mm high rim flange but B has only a 14 mm. JJ designation is most common on 4x4 and SUV vehicles.

How do you tell what your rims are made out of?

A magnet will tell you whether a wheel is steel or aluminum and that's a pretty simple test to find out what the material the wheel is made out of that anyone with a magnet can perform themselves.

What is BMW wheel bolt pattern?

Nearly all BMWs have 5 lug bolts in a 120mm bolt circle. Beginning with the G01 7-series chassis in 2009, all G-chassis use a 5x112 bolt pattern - the same number of lug bolts but in a 8mm tighter circle. This is also the spec used by Audi, VW, and Mercedes.
