METHOD OF PRODUCING A TIRE HAVING TREAD OF EXCELLENT OZONE-AGEING RESISTANCE

摘要

The present invention relates to a method for producing a tire with improved ozone aging resistance of the tread portion.;The rubber composition used in the tire tread portion has a problem that severe cracking occurs between the tread portion blocks when driving continues in an area with high ozone concentration such as coastal region due to lack of ozone aging resistance.;The present invention is based on 100 parts by weight of the rubber component consisting of 30 to 50 parts by weight of natural rubber and 50 to 70 parts by weight of synthetic rubber, 35 to 45 parts by weight of carbon black, 1 to 4 parts by weight of high temperature wax, 1 to 4 parts by weight of low temperature wax Tread characterized in that the rubber composition is prepared by blending an additive used in the rubber composition for tires and the tire, and the tread portion of the tire is manufactured so that the rubber composition is placed on the ground surface of the tread portion at a thickness of 0.1 to 1.0 mm. The present invention relates to a tire manufacturing method with improved negative ozone aging resistance.;According to the method of the present invention, a tire in which a rubber composition having excellent ozone aging resistance is formed on the ground surface of the tire tread portion can prevent cracking between blocks of the tread portion.
