Abstract
PURPOSE:To improve the high-temperature reinforcibility, abrasion resistance and cutting resistance and improve the heat build-up and fatigue resistance, by adding a specified amount of resin particles formed by coating the surfaces of specified resin articles with a specified organic acid metal salt to a tread rubber composition. CONSTITUTION:A large pneumatic tire provided with a tread part, a side wall part and a bead part, wherein said tread part is composed of a vulcanizable composition comprising 100pts.wt. stock rubber comprising an isoprene rubber, a styrene/butadiene copolymer rubber or a combination thereof, 1-10pts.wt. resin particles prepared by coating the surfaces of particles of a resin based on 5-methyl-1,4-hexadiene and propylene and/or ethylene and represented by the formula (wherein R is H or CH3, and m is 5-100) with an alpha,beta-ethylenically unsaturated carboxylic acid metal salt, and at least 4pts.wt., per pt.wt. this resin, reinforcing carbon black of an iodine adsorption >=85mg/g and a DBP absorption >=100mol./100g. By this improvement, it is possible to improve the cutting resistance and abrasion resistance of a tire and to improve markedly its life under conditions on a bed road.
