How To Measure The Wheel Bolt Patterns of Your Go-Kart

measure wheel bolt pattern (1)

You must understand how to measure go-kart wheel bolt patterns when building or replacing go-kart wheels.

Get familiar with the correct measurement techniques if you plan to build your own go-kart.

Bolt hole diameter, bolt circle diameter, and the number of bolts make up the dimensions of a go-kart wheel.

Our guide shows you how to measure the bolt patterns of go-kart wheels in detail. You need to note how many bolt holes there are since that affects the measurement technique.

Types Bolt Patterns on Go-Karts

The size of go-kart wheels varies with each type. The most common wheel pattern for go-karts is the 3-bolt pattern. Custom go-karts, homemade karts, and off-road karts generally have wheels between 4 and 8 bolt holes.

We will concentrate on measuring three-lug, four-lug, five-lug, and six-lug wheels since this is what go-karts usually use.

The Difference between Metric & American Wheels

There are different units of measurement for wheel descriptions in some regions when it comes to go-kart wheels. Go-kart wheels in the US use imperial measurements. Thus, the size will be 3 1/4″ x 2.5″.
The bolt holes in this wheel measure 1/4-inch in diameter, and the bolt circle measures 2.5 inches in diameter. Most American manufacturers use US-style go-kart wheels.

In contrast, metric go-kart wheels are also available. Often used outside of the United States, particularly in Europe and other parts of the world, metric wheels use metric units of measurement.

The description of a metal go-kart wheel is 3/58mm. There is usually a separate reference to the bolt hole diameter. As a result, the bolt circle of the wheel is 58mm, and the wheel has 3 bolts.

There is no difference in the measurement of US wheels and metric wheels. Hence, the technique that you just learned above works on all go-kart wheels with standard dimensions.

Measuring Wheel Bolt Patterns

In order to determine how to measure your go-kart wheel, you must identify how many bolt holes it has, as the method depends on that. By laying the wheel sideways, you’ll be able to see the circular shape of the wheel from the top, which will help you identify the bolt holes. A large hole is present in the middle, which is for the wheel hub.

Measuring 3-Lug Bolt Pattern Wheels

This can be a challenge since you need to take an extra step. As an example, let’s take a 3-1/2″ x 2.5″ go-kart wheel.

There are three bolt holes in the wheel indicated by the first digit. Bolt holes have a diameter of 1/4, and bolt circles are 2.5-inches in diameter.

To measure a 3-Lug bolt circle, you create a circle that passes through the middle of each bolt hole. The bolt hole circle is 2.5 inches in diameter in this example.

Measuring 4-Lug Bolt Pattern Wheels

It is easier to measure 4-lug wheels when they have four lugs. Since the bolt holes are evenly spaced, it is not necessary to draw an imaginary circle. Just measure the first to last bolt hole that crosses the center hole of the hub. Make sure you measure each bolt hole’s distance starting and ending at the center. It’s the bolt circle diameter, in this case, 6 inches.

Measuring 5-Lug Bolt Pattern Wheels

Likewise, measuring go-kart wheels with five lugs is relatively straightforward. The bolt spacing should be one bolt on either side of the two bolts you select.

Now measure to the other bolt hole from the outer wall of the bolt hole. You will get the bolt circle diameter for a 5-lug go-kart wheel by measuring this distance. For our example, we have a 5 1/2′′ x 6′′ wheel with a diameter of 6′′ bolt circle.

Measuring 6-Lug Bolt Pattern Wheels

The measurement of go-kart wheels with six lugs is the same as measuring wheels with four lugs. Simply choose two bolt holes opposite each other since all 6 bolt holes have equal spacing.

You should see that both sides have 2 bolt holes. Next, measure the centers of both bolt holes. As indicated, the bolt circle diameter in our example is 6 inches.

What Wheels Should You Use for a Racing Go-Kart?

Your go-kart will have the wheels that you decide to use. It is impossible to choose one system over another. The go-kart wheel you should make use of depends on your current setup. Regardless of your wheel type, you must ensure that your hub corresponds to the wheel dimensions, irrespective of the wheel type you choose.

We recommend going with a wheel and hub standard that is most affordable when building your own go-kart. Apart from racing go-karts, go-karts of other types typically use wheels with four to eight bolts.

FAQs

How do you measure a 5 lug bolt pattern?

Quickly estimate the bolt pattern for 5 lugs by determining the distance from the back of one hole to the next one’s center. Take the distance from center to center of the two holes across from one another on a 4-lug wheel.

Are all 5 lug bolt patterns the same?

Depending on the number of lug bolts and the distance of each hub bolt, you can determine the pattern of hub lug bolts. Except for 5-lug patterns, you can measure all patterns in this way. The measurements are slightly different if your trailer wheel hubs have five lug bolts. Whenever you measure, skip one bolt.

What is a 5×5 5 bolt pattern?

The 5×5 5 Bolt Pattern, or Pitch Circle Diameter (PCD), is based on the number of studs (5) and the bolt circle diameter (5.5), the round notional circle based on the studs’ center positions.

What is the most common bolt pattern for 5 lug wheels?

Five on 4-1/2 is the most common bolt pattern with 5 bolts. The 5 bolt pattern can also come in the formats 5 on 4-3/4, 5 on 5, and 5 on 5-1/2. Before buying new wheels, be sure the bolt pattern matches your vehicle.

Final Thoughts

Hopefully, our guide helped you apprehend how to measure go-kart wheels better. You can follow a simple rule.

If your wheel hub has odd-numbered bolt holes, select two opposite bolt holes across the hub and measure the distance from one bolt hole end to the center of the other, except for 3-lug go-kart wheels, where you must draw an imaginary circle.

The two-bolt holes you select must be opposite each other, crossing the wheel hub, for wheels with even numbers of bolt holes.

Calculating the distance between the first and second bolt holes will be necessary here. Always be precise whenever you measure your wheels, so you don’t get the wrong wheels or hubs!
