February 28, 2021

Using the illustration below as guide, measuring backspacing. The number you see will be the actual measurement of the bolt pattern.

Measure from the center of one bolt hole (or stud if it is still one the bike) across the axle hole to the center of the bolt hole on the other side.

How to measure rim bolt pattern. You need a scale or gauge. Remember, the diameter of circle may vary. To measure the bolt pattern, we first need to count the number of bolt holes that are in (or need to be in) the rim and make sure it matches the axle hub.

So, you have to measure from the center of one hole and end up to the center of the opposite hole. Regardless of how many lug nuts your wheel has, if it’s an even number, you can measure the diameter this way. The offset of your rims can be measured in two easy steps:

5 or 7 (or 9) bolt pattern is trickier, so pay attention: Measure the distance from the center of your rim to the mounting plate. When it comes to 6 bolt rim, the measurement process is also easy.

Bolt pattern or bolt circle is the diameter of an imaginary circle formed by the centers of the wheel lugs. Measure center to center of two holes directly across from each other. To find your bolt pattern, measure the distance as accurately as possible and then find the corresponding bolt pattern in the conversion table below.

Extend the ruler directly across from the bolt to the space across from the bolt, located in the center of two bolts or lugs, to determine the measurement. How to measure wheel bolt pattern. That measurement is your bolt pattern diameter.

Some atv models use a different bolt pattern on front and back so you'll want to double check yours before purchasing new wheels. Locate the inside center of your rim. Measure from the center of one lug holes to the.

The combination tool according to claim 1, including an indented portion in the edge of the first plate with the smaller diameter. If you would like to determine the bolt pattern of your car or a set of rims, the first thing you need to do is count the number of studs. If there are 4,6 or 8 studs, simply measure the center to center distance between two studs that are across the hub from each other.

Measure from the middle of one stud to the outside of the second stud (skipping a stud). To measure 5 lug pattern wheels, hold the end of the ruler or tape measure to the center of one bolt. It basically goes the same as the 4 bolt rim.

Now, start at the outer wall of the bolt hole and measure all the way to the center of the other bolt hole. Measure from outer edge of one bolt hole (or stud) to outer edge of opposite bolt hole (or stud). The accurate measurement is depicted here and can only be measured with a special tool called a bolt pattern gauge or by using a complex geometric equation.

You use the number of bolts to determine the method necessary to measure your rim’s bolt pattern. Count the number of bolts that go around the very center of your rim. If there is an even number of lugs:

So if you see 4 1/2 inches, you have a 5 on 4 1/2 ( also 5×4.5 and 5×114.3) bolt pattern. You can estimate the measurement by using a straight line from the backside of one hole to the center of the third bolt hole. If you need the 4, 6 or 9 lug page look here how to measure 4, 6 or 8 lug wheel bolt pattern if you want a more accurate approach check out the wheel bolt circle calculators

Measure the distance between 2 parallel lug nuts for wheels with an even number of bolts. The diagrams below indicate the proper measuring methods. 4, 5, 6, or 8.

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. Bolt pattern the measured diameter of an imaginary circle formed by the centers of the wheel lugs or bolt holes. A 4 lug bolt pattern means that the wheel has 4 lug hole spaced evenly on a circle.

Offset is usually measured in millimeters for more accuracy. When measuring your atv's bolt pattern you will want to check both the front and rear. The bolt pattern spacing can also be measured with a regular tape measure.

The “bolt pattern” specifically refers to the layout and distance pattern that the lug nuts are bolted to the wheel or rim. Measuring your atv's bolt pattern: You have 4 lug (bolt) rims on your machine, but i will show 3 and 5 bolt rims also.

An example of a measurement for a 4 lug pattern is stated as 4 on 4 (inches). Measure from outer edge of one bolt hole (or stud) to halfway through the opposite bolt hole (or stud). If your wheel has an even number of bolts, then take a tape measure and measure from the center of 1 lug nut to the center of the lug nut directly across from it.

A user can measure the wheel axle bolt pattern with the first plate and scale exposed, and reverse the device to measure the wheel rim bolt pattern for proper alignment and diagnosis with the second plate exposed. Other common bolt patterns are 5×4.75 and 5×5. Select 2 bolts that have a 1 bolt spacing on either side.

To measure your bolt pattern, pick the illustration below that represents your wheel stud pattern and measure as described below each illustration. For a 4 lug wheel, measure center to center of two holes directly across from each other. That should get you your bolt pattern measurement.

Same with 6, 8, or 10 bolt pattern. You measure from the back of one lug (skip to next lug as shown) and to the center of that lug. 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.

Common bolt patterns are 4, 5, 6, or 8 lug holes. Backspacing is the distance between the back of the rim flange and the mounting pad (where the hub attaches). Measure using the metric side of the ruler, in millimeters.

There are only 4 possible configurations: You can choose basically any hole to start with, but, you have to end up in the center of the opposite hole. How to measure your trailer wheel bolt pattern if you're replacing your trailer wheel, you've no doubt realized you need to know something called the bolt pattern (also called the lug pattern or bolt circle).
