Is PCD the same as bolt pattern?
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 wheel specs?
PCD stands for Pitch Circle Diameter which basically means the diameter of an imaginary circle running through the centre of each bolt hole. The most common PCD values are 100mm and 114.3mm, the difference arising due to manufacturers using metric or imperial measurements (4.5 inches = 114.3mm).
What does PCD 114.3 mean?
Pitch Circle Diameter
PCD (Pitch Circle Diameter) is the measurement of the diameter of the imaginary circle drawn through all of the wheel bolts or studs on a wheel. A ‘pcd’ of 4/114.3 means the wheel is four stud with a pitch circle diameter of 114.3mm.
What are 5×120 wheels?
5×120 bolt pattern or 5×4. 7 in inches is used on 168 models. Wheels with this bolt pattern are most often used on BMW, BMW Alpina, JAC, Holden, BYD, Cadillac. These numbers mean that the wheel has 5 lug holes, that form circle between the centers of these holes, and this circle diameter is 120 mm or 4.7″.
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.
What is the difference between PCD and BCD?
Chainrings are sold by number of bolts and PCD or BCD, which is the same thing and stands for Pitch Circle Diameter or Bolt Circle Diameter. Easier than diameter to measure is the centre-to-centre distance between two adjacent bolts.
What bolt pattern is a Jeep Wrangler?
For example, all JK Wrangler vehicles (2007-18) have a 5×5 bolt pattern – meaning five lugs with a five inch spacing. Earlier TJ Wrangler models (1997-06) and YJ editions (1987-95) employ a 5×4. 5 pattern.
Does PCD have to be exact?
You need to measure between the centres of opposite studs, which will typically produce a figure such as 100mm. While most PCDs will follow this rule, it is usually worth measuring for an exact figure. There are some exceptions to measurements, particularly when dealing with three or five studded parts.
What does PCD 100 mean?
100 is the simplest. So lets say you have an alloy with 4×100 PCD. It means it has four holes and the distance between one bolt hole and the one opposite to it is 100 mm. It simple means the circumference on which all 5 holes are drilled, it has a diameter of 114 mm. Same way 6 bolt wheel PCD is measured.
What is the most common wheel PCD?
The most common PCD values are 100mm and 114.3mm, the difference arising due to manufacturers using metric or imperial measurements (4.5 inches = 114.3mm). You will need to ensure that your new wheels have the same stud pattern (4 and 5 stud shown above) and same PCD as the wheel hub on your vehicle.
Is 114.3 the same as 4.5 bolt pattern?
yes they are the same bolt pattern.
What does PCD stand for in wheel size?
PCD (Pitch Circle Diameter) is the measurement of the diameter of the imaginary circle drawn through all of the wheel bolts or studs on a wheel.
How big is a bolt pattern on a wheel?
Bolt Patterns (PCD) Bolt pattern or bolt circle is the diameter of an imaginary circle formed by the centers of the wheel lugs. Bolt patterns may contain 4-, 5-, 6-, or 8-lug holes or studs. A bolt circle of 4×100 would indicate a 4-lug pattern on a circle with a diameter of 100mm.
How to find the PCD of a 5 stud wheel?
Measuring the PCD of a 5 stud wheel is a tricky business. It is much easier to determine the PCD by checking the manufacturers’ original specifications or by checking our PCD reference guide for each model.
What is the diameter of a bolt circle?
Bolt pattern or bolt circle is the diameter of an imaginary circle formed by the centers of the wheel lugs. Bolt patterns may contain 4-, 5-, 6-, or 8-lug holes or studs. A bolt circle of 4×100 would indicate a 4-lug pattern on a circle with a diameter of 100mm. The diagram indicates the proper measuring methods.
