Proper maintenance of the YIKONG YK4107 RC Car Tires (Part No. 21099) helps extend tire life, maintain excellent traction, and improve the off-road performance of your YIKONG YK4107 RC Car. Since these are padded tires, they require glue on both sides during installation and should be secured with M4 nylon lock nuts. Regular maintenance should also include inspecting the tires, foam inserts, and glued areas.

Why Should You Regularly Maintain the YIKONG YK4107 RC Car Tires?
The tires are the only components of the YIKONG YK4107 RC Car that make direct contact with the ground. Their condition directly affects traction, handling, climbing ability, and overall off-road performance.
Without regular maintenance, you may experience:
- Excessive tread wear
- Tire glue coming loose
- Water-soaked or deformed foam inserts
- Reduced traction
- Tire separating from the wheel
- Tire vibration while driving
Regular maintenance is especially important after driving your YIKONG YK4107 RC Car through mud, sand, rocks, or water.

How to Maintain the YIKONG YK4107 RC Car Tires?
Regularly cleaning the tires, checking the glued areas, and inspecting the foam inserts are the keys to maintaining reliable traction and extending the service life of your YIKONG YK4107 RC Car Tires.
Step 1: Turn Off the Vehicle
Turn off your YIKONG YK4107 RC Car and disconnect the battery.
Remove the tires to allow for a complete inspection and cleaning.
Step 2: Clean the Tires
Use a soft brush or damp cloth to remove:
- Mud
- Sand
- Small stones
- Dust
Avoid using harsh chemical cleaners, as they may damage the rubber compound of the YIKONG YK4107 RC Car tires.
Step 3: Check the Tire Glue
These Padded Tires require tire glue on both sides between the tire and the wheel during installation.
Inspect for:
- Loose glue
- Partial separation
- Weak or uneven bonding
If the glue has failed, re-glue the tire promptly to prevent it from separating during high-speed or off-road driving with your YIKONG YK4107 RC Car.
Step 4: Inspect the Foam Inserts
Check whether the foam inserts are:
- Water-soaked
- Deformed
- Aged
- Damaged
If the foam becomes wet, remove it and allow it to dry completely before reinstalling. This helps maintain proper tire balance and traction on your YIKONG YK4107 RC Car.
Step 5: Check the Lock Nuts
This product is designed to be secured with M4 Nylon Lock Nuts.
Inspect whether:
- The lock nuts are fully tightened.
- Any nuts have become loose.
- The nylon locking insert is worn.
Replace worn lock nuts when necessary to keep the tires securely mounted on your YIKONG YK4107 RC Car.

FAQ
Q1: Which models are these Tires compatible with?
These tires are designed for the YIKONG YK4107 RC Car.
