FIELD: automotive engineering.
SUBSTANCE: tire (1) comprises a reinforcing tape of a shield layer which is formed of polyethylene terephthalate cords, secant modulus of which is from 2.0 to 2.5 mN/dtex⋅% at 160°C at relative elongations from 3 to 5%; which strength during thermal shrinkage exceeds 2 mN/dtex at 177°C (according to ASTM D885) and which are obtained by their relaxation by 1-3% at 220-240 °C and subsequent cold drawing by 1-5% at 140-200 °C.
EFFECT: providing durability at high speeds and reduction of time flat sections in the tire as a result of cooling during parking after driving at high speed.
