Polyurethane Tire – Advantages & Applications

Polyurethane tires boast remarkable comprehensive performance. They are puncture-proof and never need inflating, while offering excellent shock absorption and quiet operation. Featuring high safety, environmental friendliness and outstanding durability, these tires require almost no routine maintenance. Due to these prominent strengths, they have a wide range of applications. They are commonly equipped on wheelchairs, mobility scooters, bicycles, baby strollers, electric scooters and tool carts for diverse daily and industrial use.
