Golf cart wheels and tires are some of the most essential components on your golf cart. They play a massive role in your golf cart's ride quality and performance and can really impact how much you enjoy driving it.

Considering their importance, people often question and debate what tires and wheels they should add to their golf carts. These questions often revolved around golf cart tire sizing, what tread they should have, and what tire will perform the best.

Another question people often have is regarding golf cart tire speed and load ratings, also known as the tire service description. As golf carts continue to get faster and faster, these two pieces of information become more critical.

To help get you the most up-to-date information, we created the following charts for golf cart service descriptions. Let's take a look!

Golf Cart Tire Speed and Load Rating: How To Read The Numbers

On golf cart tires with speed and load ratings, you will find a number and letter combination close to the tire size write-up (ex. 205/30-14). Make sure you distinguish the speed and load rating number from the DOT number, which is something separate.

The DOT number will typically have "DOT" written right before it and will have a longer string of numbers and letters.  See below for some examples of the tire service description on some tires we have here in the shop.

When looking at the numbers and letters: the number represents the tire load rating, while the letter represents the speed rating.

So, for example, a tire that has a speed and load rating of 71N would have a load rating of 71, and a speed rating of N. Use the charts below to determine what the numbers correspond to:

As noted by BF Goodrich, speed ratings account for more than just how fast you can go. Speed ratings also refer to ride comfort and the wear and tear of the tire. A higher speed rating will typically correlate with better grip and stopping power but less lasting tread life.

What Does This Mean For Your Golf Cart?

Question mark

Now that we've looked at the numbers, there are a few things you need to know about golf cart tire speed ratings:

First, only some tires will have a speed or load rating. This lack of a rating doesn't indicate an issue or a problem with the tire; it just means it has yet to go through the testing required to receive those ratings.

As we have stated in other articles about golf cart wheels and tires, for golf carts, speed and load ratings aren't as important as they are in automotive tires that need to be able to handle excessive speeds.

As a result, in our opinion, the speed or load rating of various golf cart tires shouldn't be the sole factor in determining which wheel and tire combo to buy.

Speaking of buying... If you need help figuring out what tires are best for you and your cart, check out our guide for purchasing new tires for your golf cart!

However, that leads us to our second point: these ratings do give you some indication of the performance you can expect from your tires. Especially if you have a high-performance cart that can travel at speeds more than 20 mph.

So it is information worth knowing- even if it isn't the main factor in purchasing new golf cart wheels and tires.

When purchasing a new wheel and tire combo for your golf cart, it is best to look at the whole picture.  Things like the terrain you most often drive on, wheel and tire combo overall height, the tire tread, etc. also play a major role.

Thinking through the tire speed and load ratings, along with these other factors should give you a well-rounded picture of what is best for you and your golf cart.

Bonus- If my tire is rated for over 70 mph, I can use it on the highway right?

Technically yes, but...

That still isn't a great idea. Most golf cart tires will have printed on their sidewall something to the effect of "Not Rated For Highway Use". We recommend not taking your golf cart to automotive speeds with regular golf cart tires. The small exception to that rule may be steel-belted radial golf cart tires which are about as close to automotive tires as you can get.
