Garden Tire Size Guide: How to Read Tire Sizes for Mowers, Golf Carts, and Utility Equipment

One of the most common mistakes when buying lawn mower or golf cart tires is ordering the wrong size. Tire sizing can look confusing, but once you understand how it works, choosing the correct tire becomes simple.

At Antego Tire & Wheel, we help customers match tire sizes every day. This guide explains how to read lawn and garden tire sizes, what the numbers mean, and how to avoid costly fitment issues.

Why Tire Size Matters

Installing the wrong tire size can cause:

• Rubbing or clearance issues

• Poor handling

• Transmission strain

• Uneven cutting on mowers

• Speedometer inaccuracies on golf carts

Correct sizing ensures:

• Proper performance

• Safe operation

• Long tire life

• Manufacturer-approved fitment

Understanding Standard Lawn & Garden Tire Sizes

Most lawn mower and golf cart tires use a three-number sizing format, such as:

18x8.50-8

Here’s what each number means:

First Number: Overall Tire Diameter

• 18 = Tire height in inches

Second Number: Tire Width

• 8.50 = Tire width in inches

Third Number: Wheel (Rim) Diameter

• 8 = Wheel diameter in inches

➡️ This tire is 18 inches tall, 8.5 inches wide, and fits an 8-inch wheel.

Common Lawn Mower Tire Sizes

Some of the most popular mower tire sizes include:

• 15x6.00-6

• 16x6.50-8

• 18x8.50-8

• 20x10.00-8

• 22x11.00-10

• 23x10.50-12

Always match all three measurements unless your equipment manufacturer approves an alternative size.

Golf Cart Tire Sizing Explained

Golf cart tires may appear in two formats:

Standard Turf Style

Example: 18x8.50-8

Low-Profile or Street Style

Example: 205/50-10

Low-profile sizes use metric measurements and are common on modified or street-driven carts. Always confirm clearance before switching styles.

Bias Ply vs Metric Tire Sizes

Some lawn and garden tires use metric sizing formats similar to automotive tires. These require careful conversion to avoid mistakes.

When in doubt:

• Stick with OEM sizing

• Or choose pre-mounted tire & wheel assemblies for guaranteed fitment

Pre-Mounted Tire & Wheel Assemblies: No Guesswork

One of the easiest ways to avoid sizing errors is purchasing complete assemblies.

Benefits of Assemblies

• Tire and wheel pre-matched

• Correct bolt pattern

• Valve stem installed

• Faster installation

• Reduced downtime

Antego offers assemblies for:

• Lawn mowers

• Golf carts
