Technologies

Nylon casing: Nylon is a strong, durable synthetic fiber traditionally used to make tough tire casings. Nylon threads are thicker than cotton threads, so fewer fit in an inch. Nylon casings are strong and durable, which extends their wear life. However, this synthetic fiber is not as elastic (soft and flexible) as cotton.
