Size format: Overall Diameter × Section Width - Rim Diameter (all in inches). OD and Width are nominal — actual measurements vary slightly by brand.
This golf cart tire size calculator uses the flotation tire format (Overall Diameter × Section Width - Rim Diameter) to calculate key dimensions for any golf cart tire. It also converts between flotation and P-Metric sizing, which is useful when sourcing replacement tires or checking load ratings across different size systems.
Golf cart tires use flotation sizing: 18×8.5-8 means 18 inches overall diameter, 8.5 inches wide, on an 8-inch rim. Enter these three numbers to instantly see sidewall height, circumference, and revolutions per mile for your specific cart setup.
- Select 'Flotation to P-Metric' mode in the calculator below.
- Enter the Overall Diameter (first number, e.g., 20 for a 20×10-10 tire).
- Enter the Section Width (second number, e.g., 10 for a 20×10-10 tire).
- Enter the Rim Diameter (third number, e.g., 10 for a 20×10-10 tire).
- Click 'Convert' to see the overall diameter, sidewall height, circumference, and revolutions per mile.
- Compare sizes using the common golf cart tire chart below.
What size tires does a standard golf cart use?
Most stock Club Car, EZGO, and Yamaha golf carts come with 18×8.5-8 tires on 8-inch wheels. This means 18 inches overall diameter, 8.5 inches wide, on an 8-inch rim. Some models use 18×9.5-8 on the rear for extra stability. For lifted carts, 20×10-10 and 22×11-10 are the most popular upgrades.
How do I read a golf cart tire size like 20×10-10?
Golf cart tires use a flotation format: Overall Diameter × Section Width - Rim Diameter, all in inches. For 20×10-10: the tire is 20 inches tall, 10 inches wide, and mounts on a 10-inch rim. This is different from the P-Metric system (like 225/45R17) used on car tires. Use this calculator to convert between formats or find key dimensions.
What lift kit do I need for 22-inch golf cart tires?
To safely fit 22-inch tires (e.g., 22×11-10) on a standard golf cart, you typically need a 3–4 inch lift kit. Without a lift kit, larger tires will rub on the body, fenders, and suspension components. Always check the clearance requirements for your specific cart model and lift brand before purchasing.
What is the correct tire pressure for golf cart tires?
Standard golf cart tires typically run at 15–22 PSI. Larger all-terrain and lifted cart tires may run slightly higher at 18–25 PSI. Always check the maximum pressure listed on the tire sidewall and start at the lower end of the recommended range. Under-inflated tires wear unevenly; over-inflated tires reduce traction and ride comfort.
Can I put car tires on a golf cart?
Not directly — golf carts use small-diameter rims (8–12 inches) and low-speed-rated tires with flotation sizing. Standard car tires use P-Metric sizing and are designed for much higher speeds. Some golf cart owners use low-profile "street" tires on lifted carts with larger rims, but these require aftermarket wheels and appropriate load/speed ratings.
