ExplosionProof Safety Layer Features an integrated sealing layer that instantly closes punctures up to 6 mm from nails or thorns. This maintains stable air pressure and helps prevent sudden flats that could cause loss of control. CoolRunning Radial Construction Radial design delivers up to 30 percent lower rolling resistance compared to traditional biasply tires. This allows the tire to run cooler, reduces wear, and extends longevity while increasing travel range by up to 15 percent per charge. Smooth and Quiet Ride Flexible sidewalls absorb shocks and vibrations more effectively than solid rubber tires. Noise and harshness are reduced, making travel more comfortable across rough sidewalks, brick paths, or light trails. Applications Daily commuting on an electric scooter, where reduced rolling resistance can mean more distance per battery charge. Wheelchair use, providing a smoother, quieter ride and reducing hand strain over uneven surfaces. Recreational or utility riding on mixed terrain, ensuring better comfort and safety when encountering debris or obstacles.
