Black Cat premium inner tube, 2.0mm thickness, 8.5x2, 90x90° valve

The premium 8.5×2 (156) inner tube with a 2.0 mm thickness and a 90×90° valve is a reinforced replacement part designed for electric scooters equipped with 8.5-inch wheels. It is thicker than a standard inner tube, improving its puncture resistance and extending its lifespan.

- Product Overview

This inner tube is made of high-density reinforced rubber, offering better sealing and increased protection against pinch flats and wear. Its 2.0 mm thickness allows for greater shock absorption and reduces the risk of punctures during everyday use.

The 90×90° angled valve makes inflation easier, especially on scooter wheels where access to the valve is sometimes limited. This type of valve is often used on certain models to simplify use with a pump or compressor.
