When it comes to the maintenance of your golf cart, golf cart tire pressure is one of the most important metrics to keep an eye on. In general, you want to maintain a tire pressure of between 15 to 25 PSI (1.03 to 1.72 bar) in order to keep your tires functioning and to extend their lives.
As variations in climate can change the effective pressure within your golf cart tires even after filling them to a specific pressure, we recommend filling golf cart tires to a value in the middle of the accepted range: 20 to 22 PSI (1.38 to 1.52 bar).
What Can Happen at Golf Cart Tire Pressure Extremes?
If you allow your golf cart tire pressure to drop too low it can significantly increase the wear on your tires. Poorly pressurized tires also lose more energy to friction, so your cart's battery and motor will wear down faster as well.
On the other hand, you can't just fill your golf tires to the highest pressure possible. A tire pressure that is too high will reduce the traction and shock resistance of your golf cart tires, resulting in an uncomfortable and jostling ride. In addition, overfilling your tires can cause them to explode under the wrong circumstances.
Should I Pick a Golf Cart Tire Based on PSI?
Your choice of golf cart tire is dependent mostly on your intended application for your cart as well as the size. If you plan to use the cart primarily on golf courses, Turf (aka Street) tires are optimal, as their mild tread is well-suited for smooth pavement. If you plan to use the cart for more industrial or off-road applications, Knobby (aka Off-Road) tires are preferable, as they are more durable in rough terrain. However, as Knobby tires wear much more quickly on pavement, it is important to purchase them only if you intend to make use of their advantages.
Once you have chosen the proper tire for your golf cart, (if you haven't read our guide on how to read golf cart tire sizes we recommend you check it out), you can find the ideal tire pressure on the outside edge of the tires. Your golf cart manual should also carry recommended inflation values for each potential type of tire.
Standard golf cart tires will usually have a diameter of 8 to 10 inches, while larger golf cart tires can be as wide as 12 inches in diameter. Larger golf cart tires can often require modified golf cart wheel wells to install, so make sure to check what is required for your golf cart's model.
How Should I Go About Replacing My Golf Cart Tires?
Similar to in your car, the golf cart tires should be rotated frequently in order to maximize their useful life. While uneven tread wear on car tires is often caused by variable turn radii for left and right-hand turns, uneven tread wear on golf cart tires can also be attributed to an uneven weight distribution between the forward and rear ends of the cart.
Once you have exhausted the useful life on your golf cart tires you should replace them with new tires. Contrary to popular belief, mildly used golf cart tires are not the superior option for retrofitting your golf cart. The benefits of longer life and a performance warranty mean that buying new golf cart tires and wheels is usually the preferred option for golf carts.
How Else Can I Save Money on My Golf Cart Tires?
Being sure to drive safely and conscientiously—a flat tire can be an expensive accident. Carrying a quick patch kit or aerosol spray tire sealant are excellent ways to ensure that you don't have to call immediately for a repair company if your golf cart does get a flat tire.
