Purchasing and Replacing
Today, some golf cart tires are sold already mounted on the wheel. This is because the tires are so small, and the rims are cheap enough that it makes sense to sell both together instead of removing a tire to place it on an old rim. When this is the case, you can simply jack up your golf cart with a car jack, or if you have a special golf cart jack, remove the lug nuts from the old tire and mount the new tire and wheel onto the cart.
Removing a Tire from the Wheel
A golf cart tire can be removed from a wheel rim. To do this, remove the lug nuts from the golf cart tire using an extension ratchet or properly sized tire iron. Remove the old tire, and then place it on a solid work bench. Release the air by attaching a valve tool to the air valve. To break the beads, use two tire irons. Place the edges on the lip of the wheel and under the lip of the tire. Each one should be a few inches apart. Then, pull the tire over the rim. Work the tire irons around the tire until the bead is completely over the rim. Repeat this for the bead on the other side.
Replacing the Golf Cart Tire
Whether you are installing a new tire on an old rim, or a new tire and rim together, it is important to install the tire with the tread facing the proper direction. Check the manual or box to see which way the tread should face since most golf cart tires are designed with treads that perform best when moving in one direction. Before you install the tire over an old rim, clean the rim with an automotive de-greasing agent or strong cleaner, and then wash both the rim and tire in soap and water. Place the rim through the tire, and then, using the tire irons, tuck the tire lip under the edge of the rim.
Inflating a New Golf Cart Tire
Fill the tire with air using an electric air pump to the exact specifications the manufacturer suggests. Use an accurate air pressure gauge to read the pressure; do not rely on the air pump's gauge because it is not always accurate. Most golf cart tires inflate to around 20 psi. This could be higher or lower depending on your brand and the type of tire you own.
Choosing the Right Replacement Golf Cart Tires
Golf cart tires are made for specific ground types. There are tires for sand and mud with larger treads, small tread tires for grass and several other varieties. Read each tire's specifications to see what type of ground it is suited for before you buy. Also, match the tire size to your cart. The cart's documentation should provide a specific size for replacement golf cart tires. The tires need enough clearance to operate properly.
