Tire Purchasing Guidelines

Golf cart tires can be a confusing product to shop for - with so many variations and styles to choose from, how do you figure out what's right for you? Here are some general guidelines to help you understand the terminology with tires.

Golf Cart Tire Sizes

Most tire sizes are in the following format: 18x8-10. The first number, 18, is the full diameter of the tire - how tall it is in inches from top to bottom. The second number, 8, indicates how many inches wide it is. The last number, 10, is the size of the center of the tire - in other words, what size wheel will fit the tire. Therefore, an 18x8-10 tire is 18" tall, 8" wide, and can fit a 10" wheel.

Another size format you may encounter is the automotive format, which looks like 205/50-10. In this case, the first number, 205, is the tread width in millimeters. The second number, 50, is the aspect ratio (the side-wall measurement), and the third number, 10, is the size of wheel it can fit in inches.

Golf Cart Tire Treads

A sawtooth tread has a flatter pattern than more aggressive treads, making it turf-friendly and a smoother ride. It's commonly used by golfers, street-legal drivers, and casual off-roaders. For more extreme off-roading, go with a lug, knobby, or X-tread, as they are more durable and stable.

Also, many tires feature a directional tread. If you choose a tire with directional tread, be sure the tread is installed in the right direction! The tread pattern should face the same direction on the driver and passenger sides. If directional tread tires are installed incorrectly, you may have difficulty steering.

Golf Cart / Street

Offers the smoothest ride on pavement, and is a popular choice for turf applications.

All Terrain

Handles light off-road duty when needed, while also providing a good ride quality on pavement.

Agriculture & Off-Road

Aggressive tread blocks provide the ultimate off-road performance on muddy or rocky terrain.

Advantages / Disadvantages of Height & Width

The wider your tire, the more stable your golf cart will be, because it will have more contact with the ground. Some additional turning force is required when steering wider tires, although it's usually not enough for you to notice.

The taller your tires are, the more ground speed you will gain. However, keep in mind that you will lose engine or motor torque.

Golf Cart Tire Ply Rating

The ply rating is the thickness of the tire, which tells you how durable the tire will be and for what terrain it's appropriate.

A 2-ply rating will give you a soft, spongy ride on larger wheel assemblies. A 2-ply tire is ideal for golfers and can be used for light to moderate off-roading - because they're softer, they can absorb more impact, but with extreme off-roading, you run the risk of punctures.

A 4-ply tire is tougher and more versatile - it can be used for golfing, street-legal driving, moderate to extreme off-roading, and hauling.

A 6-ply tire is often used by extreme off-road enthusiasts, because its extra thickness makes it much more puncture-resistant than 2-ply or 4-ply tires.

There’s nothing like hitting the links while cruising along on your golf cart. Yet even your trusty golf cart needs a little TLC from time to time, including new or updated tires.


But did you know that not all golf cart tires are created equal or standardized? Just like different types of automobiles require different tire sizes and types, golf carts also require different tire sizes depending on the type of cart you're sporting around.

Luckily, the team at Golf Cart Garage has put together a handy guide to help you understand your options when picking out golf cart tire packages.

Before we get into the different types it's important to understand how to read golf cart tire sizes which we'll cover first. 

How to Read Golf Cart Tire Sizes

The easiest way to understand is using a few examples so let's jump to it. 

Tire sizes can be displayed a few different ways with one requiring ratios. 

205/50-10" 

  • 205 - This number is the width of the tire in millimeters (this number converts to 8 inches roughly)
  • 50 - This number is a ratio that indicates how thick the sidewall of the tire is compared to the width (first number). Generally, the larger this number is the taller the tire
  • 10 - This is the size of the tire to reference for matching the proper wheel size

18x8.5x8"

  • 18 - The tire height in inches
  • 8. 5 - The width of the tire across in inches
  • 8 - The wheel size that the tire should use

Tire Size Height Width
205/50-10 18" Tall 8" Wide
205/65-10 20.5" Tall 8" Wide
205/30-12 17″ Tall 8″ Wide
215/30-12 17.1" Tall 8.5" Wide
215/35-12 17.9" 8.5" Wide
215/40-12 18.5″ Tall 8.5″ Wide
215/50-12 20.5″ Tall 8.5″ Wide
205/30-14 19" Tall 8" Wide

Standard Golf Cart Tires

No doubt It can be confusing trying to figure out which golf cart tire size you need. For many cart owners, this might be their first new tire purchase. But don’t worry, we’ve got you covered.

Many stock golf cart tires clock in at 18 inches tall and 8.5 inches wide when full of air at the proper tire pressure. This type of tire can be fitted on an 8-inch round hub. The two most common stock tire sizes are 8 inches wide and 7 inches wide. 

However, these tires can come in other sizes as well, such as: 

  • 10-inch tires
  • 12-inch tires
  • 14-inch tires

There are even options to customize your tires depending on your needs or make/model.

Consult a Wheel Finder

If you know the basic information about your golf cart, you can eliminate the guesswork by using an application to find the correct tire size for your golf cart.

Information you will generally need includes the following:

  • The make of your golf cart
  • The model of your golf cart
  • The year your golf cart was manufactured

All of this can help you find out which tire is best suited to your golf cart. You can also keep an old tire to use as a reference. Even taking a picture of the tire may be helpful, as long as you get a close up of the tire to show any relevant information. 

Lifted and Non-Lifted Carts

Another factor that will make a difference in your golf cart tire size is whether your cart is lifted or not. Lift kits are used to create more distance between the bottom of your cart and the ground. This is useful for all-terrain situations. 

If you have a lifted cart, this will also affect your golf cart tire size. Lifted carts usually require larger tires or ones that are offset to make up for the height differential.

Wheel Offset

Some wheels have an offset that needs to be accounted for. Dealing with wheel offset might seem a bit frustrating at first. But let’s break down how to figure this out…

  • The first number in the offset is how much backspacing is being represented.
  • The second number is the distance from the mounting space (where the wheel touches the hub) to the front edge of the wheel itself.
  • You can tell your wheel is centered when there is an equal distance between the front and rear wheel edge from where the hub touches the wheel.

Know Your Profile 

There are two profiles (referring to the kind of tire tread) that golf cart tires are available in:

  1. Low Profile: Low profile golf cart tires are thin and will fit on most carts that do not have a lift kit. Think of these as being similar to the sleek, stylish and performance-minded low profile tires you’d put on a sports car.
  2. Off-Road: These golf cart tires (otherwise known as all-terrain) are thicker and intended to handle rough terrain with ease. If you don’t use your cart a lot of paved and flat/smooth surfaces, these tires might be the best option.

By knowing all the customization options on your golf cart, you can narrow down the appropriate tires for your cart. This will help make your selection less confusing, also.

Research Your Tires Before A Purchase

There is a lot of information to consider before purchasing new golf cart tires. 

The size can depend on many different factors, including:

  • The make and model of your cart
  • Whether or not you installed a lift kit
  • If wheel offset needs to be considered
  • If the tire is high or low profile

By knowing all of these factors, you can be sure to buy the right tire for your golf cart. Take the guesswork out by learning about your golf cart tire sizes before they need to be replaced.
