Golf Cart Tire Size Calculator
Dimensions, Diameter & Lift Kit Requirements for Club Car, EZGO & Yamaha
REAL-WORLD EXAMPLE
A stock Club Car or EZGO rolls on 18×8.5-8 tires — 18” tall, no lift kit needed. Upgrading to 23×10-14 (one of the most popular lifted builds) increases overall height by 5” (+27.8%) and requires a 6” lift kit for proper clearance. This calculator shows you the exact diameter change, circumference difference, and the lift kit size you will need before you buy.

Popular Golf Cart Tire Dimensions & Lift Requirements
| Tire Size | Diameter (in) | Circumference (in) | Revs/Mile | Lift Needed | Common Use |
|---|---|---|---|---|---|
| 18×8.5-8 | 18.0 in | 56.5 in | 1,121 | None (stock) | Stock Club Car, EZGO, Yamaha |
| 20×10-10 | 20.0 in | 62.8 in | 1,009 | 3" lift kit | Mild lift — most popular first upgrade |
| 22×11-10 | 22.0 in | 69.1 in | 917 | 4" lift kit | Lifted street / light trail builds |
| 23×10-14 | 23.0 in | 72.3 in | 877 | 6" lift kit | Popular aggressive lifted upgrade |
| 26×12-14 | 26.0 in | 81.7 in | 777 | 8" lift kit | Heavy lift / off-road / UTV-style builds |
Lift kit requirements are general guidelines for Club Car, EZGO, and Yamaha carts. Exact clearance depends on your specific model year, body style, and suspension geometry — always verify fitment before purchasing tires or a lift kit.
Lift Kit Quick Reference by Tire Height
| Tire Overall Height | Lift Kit Required | Notes |
|---|---|---|
| 18–19" | None | Stock clearance sufficient on Club Car, EZGO, Yamaha |
| 20–20.5" | 3" lift kit | Required to avoid fender rub on all major brands |
| 22" | 4" lift kit | Spindle or A-arm lifts recommended for this height |
| 23" | 6" lift kit | Heavy-duty lift required; verify motor/controller headroom |
| 24"+ | 8" lift kit | Major suspension build; consider motor/battery upgrades too |
How to Use This Calculator
- Enter your golf cart tire size in flotation format (e.g. 18×8.5-8 or 23×10-14) — the three numbers are Overall Height × Width-Rim Diameter.
- Optionally enter a second size to compare it against your current tires.
- Click 'Calculate Dimensions'.
- Review overall diameter, circumference, revolutions per mile, and the diameter change percentage.
- Cross-reference the lift kit table below to confirm whether your frame needs to be raised before fitting the new tire.

About Golf Cart Tire Sizing
Reading the Flotation Tire Format
Golf cart tires use a "flotation" sizing format: Overall Height × Section Width – Rim Diameter. This is more straightforward than metric car tires because the overall diameter is given directly as the first number. A 23×10-14 tire is 23 inches tall, 10 inches wide, and fits a 14-inch rim — no aspect ratio math needed.
Why Tire Size Matters on a Golf Cart
- Ground clearance: Taller tires raise the frame height, which is the primary reason lifted builds use larger tires.
- Top speed vs. torque: A larger rolling diameter covers more ground per motor revolution, which can slightly raise top speed but reduces available torque for hills and soft terrain.
- Ride quality: Wider tires with more air volume absorb bumps better on rough terrain; narrow low-profile tires feel harsher but look sportier on street-focused builds.
- Rim and lift compatibility: Each tire height bracket typically requires both a specific rim diameter and a lift kit of a matching height — upgrading tires without the correct lift kit will cause rubbing.
Typical Upgrade Path
Most stock builds start at 18" tires on 8-inch rims. A mild lift moves up to 20–22" tires on 10-inch rims with a 3–4" suspension lift. Aggressive lifted builds run 23–26" tires on 14-inch rims with 6–8" of lift, often paired with a motor or controller upgrade to compensate for the additional rolling resistance and torque demand.
