Technologies

Nylon casing: Nylon is a strong and durable synthetic fiber traditionally used to make sturdy tire casings. Nylon threads are thicker than cotton threads, so there are fewer threads per inch. The advantages of nylon casings are their strength and durability, which extend the casing's service life. However, as a synthetic fiber, nylon is not as elastic (soft or flexible) as cotton.
