The PetrolScooter 9x3.50-4 knobbly off-road tyre is designed for enthusiasts who operate Chinese off-road e-scooters and pocket bikes across varied terrains. Its primary benefit is the versatile block tread pattern that balances traction on loose surfaces with stability on smooth tarmac. While this tyre offers excellent grip, users should note that the aggressive tread profile can generate more road noise and vibration when compared to smooth street-specific pneumatic tyres.

Yes, it is designed for standard 4-inch wheel rims, which are common on many Chinese off-road e-scooters.
This product is the outer tyre only; ensure you have a compatible 9x3.50-4 inner tube available for the installation.
Yes, it is suitable for tarmac, but please be aware that the block tread will wear faster on abrasive pavement than a slick tyre.
The block tread increases surface area contact with loose terrain, providing significantly better traction on dirt and gravel.
Most scooters of this size require an inner tube. Always check if your specific rim is designed for tubeless or tubed setups before installation.
Check the pressure before every long ride to ensure optimal handling and to prevent premature wear of the sidewalls.
Ensure the bead is seated evenly around the entire circumference of the rim and check the air pressure.
Check the inner tube for punctures caused by debris inside the casing or potential damage during the mounting process.
Apply a small amount of bead lubricant or soapy water to the tyre edges to help them slip into the rim channel more easily.
To ensure a successful installation, first verify that your existing rim is a standard 4-inch diameter. During installation, it is recommended to use proper tyre levers to avoid pinching the inner tube. Always inspect the inner rim surface for sharp edges or debris before mounting the new tyre.
For care, maintain the recommended air pressure specified by your scooter manufacturer. Under-inflating this tyre can cause the sidewalls to flex excessively, leading to premature cracking, while over-inflation may reduce the effective contact patch, making the ride feel harsh. Periodically check the tread for embedded stones or glass to extend the life of the rubber compound.
