FIELD: process engineering.
SUBSTANCE: invention relates to reconditioning of tires. Reconditioned tire comprises procured tread web connected with tire base part binding surface. Tread web comprises main groove with top part extending on to tread web front surface for contact with road and extra groove with bottom part extending on to tread web rear surface connected with said base binding surface. Note here that extra groove top part is located above main groove bottom part so that extra groove top part extends on to tread web front surface unless complete main groove wear-out. Base groove is formed at tire base part to extend to tire binding surface. Note also that extra groove bottom part is hydraulically communicated with base groove.
EFFECT: material savings.
