How to read Go-karts tire size
The first number – Tire height
As is the case with most tire suppliers, the first number indicates the height or diameter of your go-kart’s tires. This number often ranges from 10″ to 12″. Off-road go-karts typically have taller tires than those used for racing. This is because they need more ground clearance to navigate rough terrain.
Smaller tire height also has its own benefits. Lower go-kart tires provide a lower center of gravity. This makes your go-kart more stable and less likely to tip over. In addition, lower tires offer:
- Less weight
- Better acceleration (but lower top speed)
- Better handling
- And very important, less expensive
Usually, the front tires’ height on go-karts is lower than the rears’.
The second number – Tire width
The second number in a go-kart tire size designation indicates the tire’s width. The range for this number is usually 4″ to 9″.
Wider go-kart tires provide more traction, which will increase your kart’s speed when cornering. This is only true if your go-kart engine is powerful enough. Otherwise, wider tires’ weight and rolling resistance will bog down your engine.
Wider tires also provide better braking because they have a larger contact patch. Again, this is only true if your kart gets a good-enough brake. If not, wider tires may just make your kart harder to stop (because the little calipers can’t handle too much rotational mass.)
The front tires are narrower than the back tires because they don’t need as much grip, and the weight is distributed differently.
You can also notice that wet tires are generally narrower than slick tires. That’s because a higher amount of force per contact surface area helps to move water aside better.
The third number – Rim diameter
The last number in a go-kart tire size is the diameter of the wheel or rim that the tire will be mounted on. The common rim diameter is usually 4″ to 6″. This size is the same for both front and rear tires.
Other numbers you need to know when choosing kart tires
Circumference
To calculate the circumference of a go-kart tire, this is the general formula:
C = πd
Where:
- C is the circumference in inches
- d is the diameter of the tire in inches
- And π is 3.14159
However, as you can see on the size chart above, some tires have the same diameter but different circumferences. Why is this possible?
It’s because the rim width affects the sidewall height, which in turn alters the tire’s circumference.
Rim (or wheel) width
Do not be confused between rim width and tire width. The width of the rim is the distance between the inside and outside of the bead seat.
Usually, this number can be found under this form: A x B
Where A is the rim diameter and B is the rim width.
Because rim diameter is already displayed in tire size (Y x Z – A), you can sometimes only see one number on the section wheel (rim) dimension. That’s also the rim width.
Tread depth
Tread depth is the distance between the top of the tread to the bottom of the deepest grooves.
The higher the tread depth, the better your kart grip on a wet surface. This is because the tread will displace water and avoid skidding.
For that reason, “wet” tires have much higher tread depth than dry (slick) tires. Meanwhile, dry tires have little to no tread to provide the most amount of grip.
According to Jones and Childers’s coefficients of friction report, a slick tire can offer a 0.9 coefficient of friction on a dry surface. But on a wet surface, this number can drop down to 0.1, which is very dangerous.
A deep-grooved tread can offer a 0.4 coefficient of friction on a wet surface and 0.7 on dry.
