Tyre issues
EZGO golf carts are simple vehicles with basic replacement parts, and most maintenance is easy to carry out if you have experience repairing and maintaining vehicles.
EZGO golf cart tyres come in a variety of sizes, with factory tyres measuring 18x8.50-8. Newer or higher-end models, such as the EZGO Liberty or RXV, may have larger wheels and tyres. Non-lifted (stock) EZ-GOs like the TXT, Medalist, and Marathon can accommodate tyres up to 20" tall without a lift kit. Taller tyres, such as 22" or 23" all-terrain tyres, will require a lift kit.
To ensure optimal performance and safety, it is important to maintain proper tyre pressure. The recommended tyre pressure for an EZGO golf cart is between 18 and 22 PSI.
One common issue with EZGO golf carts is that the rear wheels may spin freely when off the ground but fail to move when loaded or turn in opposite directions. This problem often arises from a faulty differential or damaged axle components. To address this, inspect the differential gears for wear or broken teeth, and check axle shafts and splines for damage or disconnection. Lubricate moving parts and replace any worn gears or bearings. Regular maintenance of the drivetrain prevents uneven wheel rotation and ensures smooth power transfer to both rear wheels.
Other tyre-related issues include flat tyres, punctures, tyre wear, wheel misalignment, and tyre balance problems. Flat tyres and punctures can be fixed by repairing or replacing the damaged tyres. Tyre wear and wheel misalignment can lead to uneven tyre wear and poor handling, which can be addressed by aligning the wheels and replacing worn-out tyres. Tyre balance problems can cause vibrations and uneven wear, and balancing the tyres ensures a smooth ride and prolongs tyre life.
