Problems solved by technology

[0004] Tires with low rolling resistance are designed to use a large amount of silica filler in the tread rubber composition to reduce the rolling resistance of the tire. However, the wear performance of this filler is poor, which will shorten the service life of the tire; During the process, due to avoidance driving or other reasons, the wear of the tire crown and the shoulder part will be uneven, and the wear of the shoulder part will be serious, which will reduce the service life of the tire.

Abstract

The invention provides a tire with low rolling resistance. The abrasion resistance of the tire is improved. The rolling resistance coefficient of the tire is smaller than 10.5kg / t. The tire comprises a tire tread which has a split-type structure and consists of a tire crown, a tire shoulder and a tire side, wherein the tire shoulder consists of the following rubber compositions in percentage by weight: 0-30 percent of cis alkadiene elastomer, 15-50 percent of copolymerization olefin polymer, 8-30 percent of carbon black, 10-40 percent of white carbon black and 3.5-35 percent of rubber additive. The tire shoulder of the tire with the low rolling resistance provided by the invention consists of the rubber compositions comprising 8-30 percent of carbon black; by the carbon black, the abrasion resistance of the tire shoulder is improved, the whole use cycle of the tire is prolonged, and the service life of the tire is prolonged. The tire provided by the invention also has low rolling resistance, good wetland road holding capacity and high abrasion resistance.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to a tire with low rolling resistance. Background technique [0002] When a car is running, it will produce various driving resistances, nearly 80% of which are air resistance, and the remaining 20% ​​are rolling resistance. Due to the existence of rolling resistance, tires will consume extra fuel and release CO due to frictional heat during driving. 2 , some data show that the CO released during the tire friction heat generation process 2 It has already accounted for 3% of the greenhouse gases released by global fossil fuels; moreover, a considerable part of the fuel consumption of automobiles is also used to overcome the frictional resistance of tires. According to measurement data, every 7% reduction in tire rolling resistance can reduce vehicle fuel consumption by 1%, and the reduction in rolling resistance can also greatly reduce CO 2 emissions. Therefore, by reducing the rol...
