How to Decipher the Numbers and Letters on Golf Cart Tires

If you’ve ever taken a close look at your golf cart tires, you may have noticed a series of numbers and letters imprinted on the sidewall. While it may seem like a random jumble of characters, these markings actually provide valuable information about your tires. So, let’s find out how to decipher these numbers and letters to gain a better understanding of your golf cart tires.

The first thing to note is that the tire size is typically indicated by three sets of numbers separated by slashes. For example, you might see something like 18/8.50-8 or 205/65-10. The first number represents the height of the tire in inches or millimeters, while the second number denotes the width of the tire in inches or millimeters. The third number indicates the diameter of the wheel in inches.

Another important aspect to consider is load capacity. This information can be found after the tire size designation and is represented by a letter such as B, C, D, or E. Each letter corresponds to a specific load rating ranging from light-duty (B) to heavy-duty (E). It’s essential to choose tires with an appropriate load rating for your specific golf cart model and usage requirements.

Additionally, you may come across speed ratings denoted by letters such as J, K, L, M, N, P or Q after the load capacity designation. These letters indicate how fast it’s safe to drive with those particular tires installed on your golf cart.

By understanding these key elements encoded within those seemingly cryptic numbers and letters on your golf cart tires’ sidewalls, you can ensure that you make informed decisions when purchasing new ones for replacement or upgrading purposes.

Factors to Consider When Choosing the Right Tire Size for Your Golf Cart

Choosing the right tire size for your golf cart is crucial in ensuring optimal performance and safety on the course. The size of your tires can impact various aspects such as speed, traction, stability, and overall comfort during your rounds. Let’s explore some key factors that you should consider when making this important decision.


Assessing the terrain where you will primarily be using your golf cart is essential. Different tire sizes are designed to perform better on specific terrains. For example, if you often play on hilly or uneven courses, larger tires with deeper treads may provide better traction and stability.


The desired speed of your golf cart also plays a role in determining the appropriate tire size. If you prefer a faster pace, smaller diameter tires can increase top speed by reducing rotational resistance. On the other hand, larger diameter tires offer more stability at higher speeds but may sacrifice acceleration.


It’s important to consider whether your chosen tire size will affect ground clearance or interfere with other components of your golf cart. Ensure that there is ample space between the tires and wheel wells to prevent rubbing or potential damage while navigating uneven surfaces.

Load Capacity

Take into account how much weight your golf cart will typically carry – including passengers and equipment – when selecting tire size options. Tires with higher load ratings are recommended for carts carrying heavier loads to maintain proper handling and prevent premature wear.


While not directly related to performance, many golf cart owners also prioritize aesthetics when choosing their tire size. Consider how different sizes may complement the overall look of your vehicle and align with personal preferences.

Tips for Properly Measuring and Comparing Golf Cart Tire Sizes

When it comes to golf cart tire sizes, getting the right measurements is crucial. But with so many options available, how do you know which size is best for your cart? Don’t worry, we’ve got you covered! In this section, we will provide you with some valuable tips to help you properly measure and compare golf cart tire sizes.
