1. By using rubber materials, the combination of various raw materials can be achieved, thereby extending the tire's lifespan. With a rubber tread, it offers grip, slip resistance, and abrasion resistance, along with explosionproof pressure resistance, lightweight design, and aesthetic appeal while reducing rolling resistance. 2. Compared to solid tires, pneumatic tubes and outer tires provide better cushioning capacity and impact resistance while remaining flexible enough to deliver maximum safety. 3. Compared to solid tires, they are easier to install and remove, saving time and improving efficiency. They are largely compatible with tires of the same model. Please check the images before ordering to confirm tire size and compatibility. 4. Thick tires offer impact resistance and cushioning ability. The butyl rubber tube is airtight, heatresistant, agingresistant, and chemicalresistant. Its electrical insulation performance and long lifespan provide the protection for your safe ride.
