FIELD: transport.
SUBSTANCE: treads and/or subtread for heavy vehicles consists, at least partially, of rubber composition including 80-100 wt % of natural rubber and 0-20 wt % of synthetic polyisoprene rubber. It includes also reinforcing filler containing a) 30-50 wt % of superfine silicon dioxide, and b) technical carbon in amount of 0.75-1.25 wt % defined by equation C=-0.8Si+44.3 where Si is the quantity of fine silicon dioxide. Besides, composition includes silane binder and sulfuric hardening system containing 1.5-3 wt % of free sulfur and 0.9-1.1A wt % of sulphenamide accelerator where A is defined as a function of quantity of sulfur and weight fraction of silicon dioxide of total amount of reinforcing filler.
EFFECT: increased strength of tire.
