FIELD: transport.
SUBSTANCE: invention relates to automotive industry. Tire has bead core, carcass layer, tread rubber later, inner sealing layer, side strip reinforcement and filler cord layer. It differs from known designs in the use of rubber composition (a) including (A) rubber component and (B) filler and in that its dynamic accumulation modulus (E') equals 10 MPa or less at dynamic strain of 1% at 25°C. It is characterised by magnitude Σ of loss tangent tan δ at 28 to 150°C, equal to 5.0 or less as far as physical properties of vulcanised rubber is concerned.
EFFECT: smooth run, sufficient life in run with flat tire.
