4. Setup and Installation
These tires and inserts are designed for easy installation on compatible 1.0 inch RC wheels. Assembly is required.
4.1 Required Tools (Not Included)
- Small screwdriver or hex wrench (depending on wheel type)
- RC wheel (1.0 inch diameter)
4.2 Installation Steps
- Prepare the Wheel: If using beadlock wheels, disassemble the wheel by removing the screws that hold the outer rings. For glued wheels, ensure the wheel is clean and ready for tire mounting.
- Insert the Silicone: Carefully place one silicone rubber insert inside one tire. Ensure the insert sits evenly within the tire casing. The insert provides internal support to the tire.
- Mount the Tire: Position the tire with the insert onto your 1.0 inch RC wheel. For beadlock wheels, align the tire beads with the inner and outer rings of the wheel. For glued wheels, apply appropriate RC tire glue to the wheel bead and carefully press the tire onto the wheel, ensuring a secure fit.
- Secure the Wheel: For beadlock wheels, reassemble the outer rings and tighten the screws evenly in a star pattern to ensure the tire bead is securely clamped without pinching the tire or insert. For glued wheels, allow sufficient drying time for the glue as per the glue manufacturer's instructions before use.
- Repeat: Follow these steps for the remaining tires and inserts.

5. Operation
These tires are designed for RC crawler applications, offering excellent performance on various terrains, including rocks, dirt, and mixed surfaces. The S5 compound provides a balance of softness and durability for challenging conditions.
- Terrain Suitability: Optimized for rock crawling and general off-road use.
- Performance: The super soft compound and silicone inserts work together to allow the tire to conform to obstacles, maximizing contact patch and grip.
- Driving Style: Best suited for slow-speed, technical crawling where precise traction is critical.
6. Maintenance
Proper maintenance ensures the longevity and consistent performance of your INJORA tires and inserts.
- Cleaning: After use, especially in muddy or dusty conditions, clean the tires with mild soap and water. Rinse thoroughly and allow them to air dry completely. This helps maintain the stickiness of the S5 compound.
- Inspection: Regularly inspect tires for cuts, tears, or excessive wear. Check inserts for deformation or damage. Replace any damaged components to maintain optimal performance.
- Storage: Store tires in a cool, dry place away from direct sunlight and extreme temperatures. Avoid storing them under heavy objects that could deform the tires or inserts.

7. Troubleshooting
If you encounter issues with your tires, consider the following:
- Loss of Grip: Ensure tires are clean. Dirt and debris can reduce traction. If tires feel less sticky over time, a thorough cleaning may restore performance.
- Tire Deformation/Wobble: Check if the silicone insert is properly seated within the tire and if the tire is correctly mounted on the wheel. For beadlock wheels, ensure all screws are tightened evenly.
- Premature Wear: Excessive speed or aggressive driving on abrasive surfaces can accelerate wear. Ensure your RC vehicle's suspension and alignment are correctly set up.
