Installation
The Traxxas 9672 Sledgehammer tires are pre-glued to the wheels, simplifying the installation process. Ensure your vehicle is equipped with 17 mm splined hex hubs for proper fitment.
- Prepare the Vehicle: Ensure the vehicle is powered off and stable. Remove the existing wheels and tires, if any.
- Verify Hex Size: Confirm that your vehicle's wheel hubs are 17 mm splined hex. These tires are designed specifically for this size.
- Mount the Tires: Align the splined hex of the wheel with the vehicle's hub. Push the wheel onto the hub until it seats properly.
- Secure the Wheel: Install the wheel nut onto the axle and tighten it securely. Do not overtighten, as this can damage the hub or wheel.
- Repeat for all Wheels: Follow the same procedure for all four wheels.
- Final Check: After installation, gently spin each wheel to ensure it rotates freely and is securely attached.
Usage Guidelines
These Sledgehammer tires are engineered for optimal performance in off-road environments. Their aggressive tread pattern excels in loose dirt, mud, and other challenging terrains.
- Terrain Suitability: Best suited for dirt, gravel, grass, and muddy conditions. The open block tread design helps clear debris for consistent traction.
- High-Speed Applications: The tires are TSM-rated, indicating their suitability for high-speed operation. Always operate your RC vehicle responsibly and within its design limits.
- Directional Mounting: While these tires fit both front and rear, ensure consistent mounting direction if there is a specific tread pattern orientation for optimal performance.
Care and Maintenance
Proper maintenance will extend the life and performance of your Traxxas Sledgehammer tires.
- Cleaning: After each use, especially in muddy or dirty conditions, clean the tires to remove accumulated mud, dirt, and debris. A soft brush and water can be used. Ensure tires are dry before storage.
- Inspection: Regularly inspect the tire treads and sidewalls for cuts, tears, or excessive wear. Check the wheel for cracks or damage.
- Storage: Store tires in a cool, dry place away from direct sunlight and extreme temperatures. Prolonged exposure to UV light can degrade rubber compounds.
- Adhesion Check: Periodically check the bond between the tire and the wheel. If separation is observed, re-gluing may be necessary (consult Traxxas support for recommended adhesives).
