The Reasons Why Go Karts Wheels Are Small

Go-karts typically have small wheels. As a result, driving one is a lot of fun and requires no effort. However, they pose a more significant threat than bigger vehicles, which is a double-edged sword. Care should be used while operating a go-kart on the road, as should consideration for other motorists.

Reduced wheel diameter allows for a lower center of gravity, more low-end torque, easier jacking, and quicker, more precise handling, particularly in confined spaces, which is why go-karts employ them.

Why Are Go Karts Wheels Small?

The go-karts used in the competition all look different. They are built as light and low to the ground as possible, without differentials or suspensions. Let’s examine the advantages of using smaller wheels in further detail.

Lower Center of Gravity

A vehicle’s center of gravity is improved by using smaller wheels. The clearance between the go-kart frame and the track surface is directly proportional to the tire and wheel diameter. 

A low center of gravity makes a go-kart far less likely to flip over under a sharp turn. Accelerating through turns and passing slower vehicles is crucial.

Increased in Acceleration Rate

The racer with the quickest lap time is declared the victor. They will require top-notch efficiency, notably speedy acceleration, to get there in time. Incredibly, the low-end torque band is where smaller tires shine.

Technically speaking, if the power output and torque of the engine are equivalent, smaller wheels would rotate more quickly than bigger ones. However, it doesn’t matter much since smaller wheels can only go so far before they run out of steam. The critical distinction is in the torque capacities.

Smaller go-kart tires spin up to higher RPMs more quickly, but their torque begins to fall off as they are near their range limit. Because of all the tight curves and twists that are a hallmark of go-kart circuits, low-end torque performance is essential.

That’s why go-karts need to have tiny wheels; they need to be able to accelerate quickly and get up to speed.

Easier Control

Having smaller wheels also improves handling in tight turns. The steering won’t be any more pleasant as a result of this. It is usually less comfortable since smaller tires have less air and less damping capacity.

However, smaller wheels imply that you can shift the vector of your go-kart more efficiently, allowing for sharper and more sensitive turns. 

Bigger wheels would need more room on your go-kart, but they’d provide more maneuverability. It wouldn’t work very well with sharp turns or asymmetrical corners. That’s why if you want your go-kart to be more nimble, you should choose wheels that aren’t quite as big.

Better Jacking Effort

Without a differential, go-karts must depend on jacking to navigate turns properly. Jacking happens when the inner rear wheel rises while entering a bend, causing the outside tires to receive greater force and grip.

If the tires are smaller, the vehicle may be jacked more easily. Having larger tires makes this more difficult because of their additional weight and instability. Reduced tire size allows for a safer and more efficient jacking technique by lowering the vehicle’s center of gravity.

Lighter Load

Go-karts are small, lightweight racing vehicles with excellent acceleration and maneuverability. A go-acceleration kart’s max speed will improve as it loses weight. That’s why it’s common practice to remove everything that isn’t necessary.

In general, bigger tires are heavier than smaller ones. Off-road go-karts with wider tires may weigh twice as much as those with slick tires.

Less Cost

Less material is required to manufacture smaller tires. Hence they tend to be less costly. Even though this isn’t the primary motivation for using smaller tires on go karts, it’s still a perk.

What Are The Disadvantages of Having Smaller Wheels

Because of them, go-karts designed for racing have narrower tires. The advantages they provide much outweigh those of their bigger counterparts. There are certain drawbacks to racing on narrower tires, but the benefits outweigh the negatives.

Rougher Ride 

Less air in smaller tires means less cushioning. It becomes immediately apparent due to the lack of suspension in go-karts. Their bendable bodies help to compensate to some extent.

Lower Peak Torque

While smaller wheels perform better at lower-end torque ranges, bigger wheels flourish at the higher-end torque range. It may be noticed in some situations (passing on straight parts), but it is insufficient to warrant wider tires’ usage.

Reduced Braking Potential 

If you compare the braking power of bigger wheels to that of smaller ones, you’ll see that the latter have a more significant advantage due to their greater contact area. The large back tires of go-karts attempt to make up for this shortcoming. It is not distinguishable since both types of racing motorcycles are very lightweight.

If you weigh the pros and drawbacks of different wheel sizes, you’ll quickly see that smaller wheels provide a more significant number of advantages for go-karts.

Getting the Best Wheels for Your Go Kart

When looking for replacement wheels for your go-kart, there are a few key factors to consider.


Typically, aluminum or magnesium is used for go-kart wheels. In terms of cost and performance, aluminum wheels are hard to beat. Casting and forming are the two primary production methods. However, magnesium wheels are more costly, very durable, and weigh very little.

Wheel and Hub Pattern

Next, you need to identify your wheel and hub pattern. The three most prevalent systems are the American, the Metric, and the CRG. Check out the details below to learn how to identify your pattern.


The right size is crucial. Wheel diameters for go-karts typically range between 5″ and 6″. Depending on the discipline, rear wheels are often broader than front ones. The tires and wheels must have the same width. Stay tuned for more explanation.

Wheel mounting at the front might take the form of either a spindle or a hub. US spindles measure 5/8″ in diameter for those keeping score at home, while their metric counterparts measure at either 17 mm or 25 mm. They have hub-mounted back wheels. 

As with bolt designs, hubs may be found in American and metric varieties. The front wheels of a CRG are laced in a slightly different pattern from the conventional metric design. Check out the image below if you want to know what kind of hub your kart has.

Tips on How To Store Go Kart Tires

Go-karts must be stored carefully to prevent damage to the tires while not in use. They may be stored on a wheel stand or inside the kart.

Keep Tires in a Cool, Dry Location.

Keep your go-kart tires out of the rain and moisture by keeping them in a dry location. That way, you may drive your car without worrying about its security.

Protect Against UV Rays

Protect your tires from the sun and other sources of ultraviolet radiation to extend their lifespan and prevent premature deterioration of the rubber.

Prevent Them from Getting Wet

To prevent them from being ruined, go-kart tires should never be exposed to water, such as rain. Please allow them to dry naturally before using them again if they get wet.

Keep Them Clean and Free Of Grime

Wrap your tires securely to prevent unwanted dirt and dust from settling on them. It will prevent damage to their surface and increase their grip when driving the kart.
