How do you measure wheel bolt pattern

Next youll measure how many inches apart the bolt holes are. Measure the distance between 2 parallel lug nuts for wheels with an even number of bolts.

Measure from the middle of one stud to the outside of the second stud skipping a stud.

How do you measure wheel bolt pattern. The easiest way to estimate the 5 lug bolt pattern is to measure from the back of a hole to the center of the second hole. For a 4 lug wheel measure center to center of two holes directly across from each other. Measuring a 6 bolt wheel requires you to measure center to center of two holes directly across from each other.

Finding the Bolt Circle Diameter 1. Measure the distance between 2 parallel lug nuts for wheels with an even number of bolts. If your wheel has an even.

Find the distance from the top of 1 lug nut to the center of another for wheels with odd-numbered bolts. Use a bolt circle template for a. Bolt patterns with an even number of lugs are measured from bolt center to bolt center while 5 lug bolt patterns are measured from the top of the upper lug to the center of the lower lug.

To find your bolt pattern measure the distance as accurately as possible and then find the corresponding bolt pattern in the conversion table below. The first step in determining your wheel bolt pattern is counting how many bolts or lugs your wheel has. Typically this will be 4 5 6 or 8.

Next youll measure how many inches apart the bolt holes are. These two steps together will give you your bolt hole pattern. Namely 4 lugs wheels have four holes that are symmetrical therefore measuring the bolt pattern is not a hard thing to do.

All you need to do in order to measure precisely is to start from the midpoint of one circle. Next you need to draw a line to the opposite circle to the center point as well. This will precisely show you the number of the diameter that you need to know in order to get the right wheel for your car.

How to Measure 5 Lug Bolt Pattern. Now measuring the 5. How to measure any size wheel bolt pattern from Adaptit USA Wheel adapters and spacers.

The diagram is an example of the proper method for measuring bolt patterns. The conversion of inches to mm is 1 inch to 254 mm. The bolt pattern or bolt circle is the diameter of an imaginary circle formed by the centers of the wheel lugs.

Bolt patterns can be 4 5 6 7 or 8 lug holes however tuner applications are typically 4 or 5 lug. First measure the center to center distance between two studs that are across the hub from each other. If there are 5 studs multiply the measurement by 105 to get the bolt pattern diameter.

If there are 7 studs multiply the measurement by 103. Its really very simple to measure your wheels bolt patter with a tape measure or ruler. This is sometimes called the Bolt Circle or some such thing.

One other trick is to to use a straight edge block across the BACK of two of the lugs a and then set the ruler on that and measure up to the center of the bolt like in the picture. Bolt pattern measurements are typically taken in millimeters. Bolt patterns are written with 2 measurements.

The number of bolts and the diameter from center to center. So a 4x100 bolt pattern means that there are 4 lugs with a diameter of 100 millimetres 39 in. It can appear in either inches or millimeters so be sure you know which one youre looking at.

Bolt patterns in 4- 6- and 8-lug can be measured by going from the center of a stud to the center of the stud directly across from it. A 5-lug bolt pattern is a little more difficult to measure but you can easily do that by following the diagram below. How to Measure Wheel Bolt Patterns Step 1.

Jack your vehicle up and place jack stands underneath it. Remove the wheel with the lug-nut wrench. You can also use a ratchet and socket.

Measure from center of one lug stud that the lug nut bolts on to to the center of the lug directly. Remove the existing wheel the rear wheel is usually the easiest to measure because the hub normally wont be in the way. Measure from the middle of one stud to the outside of the second stud skipping a stud.

The number you see will be the actual measurement of the bolt pattern. Bolt patterns are classified using a two number system. The first number indicates how many bolt holes are in the wheel and the second describes the diameter of the imaginary circle they make.

For example a 5-100mm bolt pattern means that the wheel has 5 bolt holes equally spaced on a 100mm circle. Bolt pattern or bolt circle is the diameter of an imaginary circle formed by the centers of the wheel lugs Note. When measuring a 5-lug wheel the measurement is only an estimate unless accurately measured using a bolt pattern gauge.

A bolt pattern gauge is a specialty tool and is not widely available. Below we illustrate how to measure your wheels bolt pattern. This technique works for trailer wheels as well as automotive and truck wheels.

Measure from the center of one lug hole – to the center of the lug hole directly across from it. Measure a five bolt wheel from the OUTER EDGE of one lug hole – to the CENTER of the lug hole most across from it. Measure a six bolt wheel from the CENTER of one bolt hole – to the.

The hub lug bolt pattern will be determined by the number of lug bolts and the distance between the opposing hub bolt see 4-lug hub diagram. All but 5-lug patterns are measured in this manner. If your trailer wheel hubs have 5 lug bolts measuring is slightly different.

Choose any lug bolt and measure the distance between the back of one lug to the center of another that is directly across from it. Be sure that you skip one bolt when measuring. You can measure the distance in either direction.
