2. Setup and Installation
Your GTW wheel and tire combo ships fully mounted and inflated, ready for installation. However, it is crucial to perform a pre-installation check.
2.1 Pre-Installation Check
- Inspect Packaging: Ensure all four wheel and tire assemblies are present and undamaged.
- Check Tire Pressure: Verify the tire pressure of each tire using a reliable gauge. Adjust to the recommended PSI as indicated on the tire sidewall or in your golf cart's manual.
- Verify Bolt Pattern: Confirm your golf cart's bolt pattern is 4-4 (4x101.6mm) for compatibility.
- Lug Nuts: Note that lug nuts are sold separately and are not included with this combo. Ensure you have the correct lug nuts for your golf cart.
2.2 Installation Steps
- Prepare Golf Cart: Park the golf cart on a level surface, engage the parking brake, and block the wheels that will remain on the ground.
- Lift Golf Cart: Safely lift the golf cart using a jack and support it with jack stands. Never work under a vehicle supported only by a jack.
- Remove Existing Wheels: Loosen and remove the lug nuts from the existing wheels, then carefully remove the wheels.
- Install New Wheels: Mount the GTW wheel and tire combo onto the wheel studs. Ensure the wheel sits flush against the hub.
- Secure with Lug Nuts: Install your lug nuts and hand-tighten them.
- Lower Golf Cart: Carefully lower the golf cart until the tires just touch the ground, but the full weight is not yet on them.
- Final Tightening: Using a torque wrench, tighten the lug nuts in a star pattern to the manufacturer's recommended torque specifications for your golf cart.
- Full Lowering: Fully lower the golf cart and remove the jack and jack stands.
- Post-Installation Check: Re-check tire pressure and lug nut torque after the first 50 miles of operation.
Important Note for Club Car Precedent Models: These models may require a low-profile spacer or lift kit to accommodate this wheel and tire combo without rubbing.
