FIELD: transport.
SUBSTANCE: tire tread has one or several reiterating spacings. Note here that every reiterating spacing comprises separate spacing with tread units including grooves formed in said tread. Note here that every spacing features length of 15-35 mm. Said treads can have weighted mean density of grooves Dw of 10 mm-1 to 37 mm-1. Tread units are also made of rubber mix based on diene elastomer, plasticizing system and cross-linking system. Said rubber mix features vitrification point of -40°C to -15°C. Note also that Coulomb modulus G* measured at 60°C at 0.5-1.1 MPa.
EFFECT: better tread braking on snowy and dry pavement.
