Elasticity: The design of the solid tire has been studied to allow flexibility. The tire can be stretched, but it will always return to its shape. Its buffer memory allows to recover its shape according to the pressure and the changes of temperature. Its dimpled microspores also allow flexibility on the road. High resistance: the solid tire has been developed to respond to irregularities in the road, a hard tire shaped and durable over time. Its manufacturing process has been designed to protect against UV. The tires are made from natural rubber to maintain road and polymer flexibility for strength. The solid tire has been developed to respond to uneven road conditions, a durable and durable tire over time.The special rubber material with grooved surface offers excellent grip and wear resistance. grooved surface provides an excellent grip, explosion-proof and resistant pressure, resistant to abrasion and durable. Non- design: The tire is designed with deep non- pattern to avoid slipping.
