Choosing the Right Go Kart Wheels

There are a few important criteria to keep in mind when selecting wheels for your go kart.

First is material. Go kart wheels are usually made of either aluminum or magnesium. Aluminum wheels are a good all-round choice balancing price and performance. They are manufactured either by casting or forming. Magnesium wheels have the advantage of being very strong and light, but are more expensive.

Next you need to know which pattern wheels and hubs you have. American, Metric, and CRG are the most common pattern. For more information on how to tell which pattern you have, see the information below.

Finally, you need the right size. Go kart racing wheels are usually either 5" or 6" in diameter. Rear wheels are generally wider than the front wheels, although that depends on the type of racing you do. The width of the wheels and the width of the tires need to match. We'll cover that more in bit.

Front wheels can either be spindle-mounted or hub-mounted. American (US) spindles are 5/8" in diameter while metric spindles are 17 mm or 25 mm in diameter. Rear wheels are hub-mounted. Hubs also come in both American as well as metrics bolt patterns. CRG front wheels have a slightly different pattern than the standard metric one. See the graphic below to tell what type of hub you have on your kart.

Now let's try an example to find the right wheel size for your tire.

Choosing the Right Wheel Size

This is not as "tuff" as you think. The size on the tire tells you all you really need to know.

Lets take a tire size of 10 x 4.50 - 5. Working backwards, the last number, 5, is the diameter of the wheel on which the tire mounts. In this case, it is a 5" wheel.

The first number, 10, represents the overall tire diameter. In this example, the tire is 10" in diameter. You don't actually need to use this number to pick a wheel.

That leaves the middle number 4.50 which we'll cover next.

Matching Wheel Width to Tire Width

The 4.50 represents the tire width in inches, and that tells you how wide of a wheel you can use. Wheel width is measured from inside bead to inside bead.

WARNING
Do NOT mount tires unless you know how to do so properly and you are following all appropriate safety measures such as tire containment devices and a locking air chuck. Air pressure should not exceed manufacturer recommendations.


American vs. Metric Bolt Pattern

The difference between American and Metric Wheels

  • American or US: A=2.125", B=1.75" with 1/4" or 5/16" studs also known as 3 on a 2.5" bolt circle. The 3 bolt holes are evenly spaced on an imaginary circle 2.5" in diameter.

  • Metric: A=50 mm (2"), B= 40 mm (1.5") with 8 mm studs also known as 3/58 pattern. The 3 bolt holes are evenly spaced on an imaginary circle 58 mm in diameter.

  • CRG Front: A=60mm (2 3/8"), B=55 mm (2 3/16") with 8 mm studs also known as 3/67 pattern. The 3 bolt holes are evenly spaced on an imaginary circle 67 mm in diameter.

    4 of 5 odd wheel sizing November 6, 2020
    Reviewer: Vincent from Quebec, Canada  
    Howdy! I have an issue here. My kart is a 1996 Top Kart and i can't find any info on it. The front wheels are 5 inches and i need to move to 6 inches wheels. My issue is this; this is a three lug wheel with 60 mm from bolt to bolt with a 55mm center. It would seem to be CRG front wheels but i have 6mm bolts instead of 8mm. Would CRG wheels fit or do i need to keep searching for the perfect fit?

    4 of 5 I need help finding rims September 2, 2020
    Reviewer: George from el paso tx  
    I have tires 12 x 8.0 - 6.

    What rims do I need!!!?? I need help, thanks!!!

    Hi George, we appreciate your interest in our products.  Unfortunately this is not a simple question.  

    Wheels depend on the hub or spindle so you need to start there - not with the tire because wheels have to match the hub or spindle.  There are three primary wheel bolt patterns US or American Bolt Pattern, Standard Metric 3/58 and CRG and other bolt patterns plus spindle mount (5/8 inch, 17mm and 25mm are most common).   So not even factoring the wheel diameter 5 inch or 6 inch there are already 6 different possible wheels for one tire size just from bolt pattern or spindle size alone.

    Please take CAREFUL measurements using a digital caliper.  You cannot tell the difference between the wheels by looking at them but they are NOT interchangeable.  Consider the difference between a 25 mm axle and a 1 inch axle which is 25.4 mm - you cannot tell the difference by looking but you can not use a 25mm hub on a 1 inch axle or a 1 inch hub on a 25mm axle.  Same for 30mm and 1.25 inch axles.  The difference is less than 2 mm but parts are NOT interchangeable.  Once you have the correct wheel for you chassis, then you can get the correct tire to go with the wheel.  The tire doesn't care if it is on metric wheel or American pattern as long as the diameter and width match.  Hope this helps.
