1. New formula and new vulcanization process improve the elasticity and durability of the support rubber, and the support is more durable at 0 air pressure 2. High-stretch and low-heat tire material, combined with precise optimization of the support ring shape, reduces the temperature of the support ring when driving at 0 air pressure 3. Reinforced bead wire structure, the 0 air pressure tire and rim are more firmly connected 4. Nano-level reinforcing carbon black is added to the tread rubber to improve the wear resistance of the tread rubber
