Abstract

The invention provides a UHP tire for promoting high speed and durability. The UHP tire comprises a tread and a side wall, wherein a first main channel, a second main channel, a third main channel, a fourth main channel and an external tread pattern are successively arranged on the tread from the inner side; the side wall comprises a waterproof line, a seam allowance and a side wall tail end in turn; the external tread pattern is composed of multiple sets of self-fixing patterns; the self-fixing patterns are arranged as three pattern horizontal channels sunken on the tread; each set of self-fixing patterns include a first pattern horizontal channel, a second pattern horizontal channel and a third pattern horizontal channel, wherein the first pattern horizontal channel and the second pattern horizontal channel are located on the tread on the two sides of the fourth main channel, and the third pattern horizontal channel is located on the fourth main channel and the tread on the two sides of the fourth main channel; central points of the three pattern horizontal channels of each set of self-fixing patterns are distributed in a triangular form; a first area, a second area and a third area are successively arranged on the side wall from the waterproof line to the tail end of the side wall, wherein the first area is in bias transition and has a width of b, the second area is in flat transition and has a width of c, and the third area is in bias transition and has a width of d; and the seam allowance is contained in the second area.

Description

technical field [0001] The invention relates to the field of tires, in particular to a UHP tire with improved high-speed durability. Background technique [0002] Tires are the load-bearing parts of the car, and its main function is to carry the load from the car and transmit power. The products have corresponding national standards and industry design specifications to meet the basic requirements of use. [0003] With the development of the automobile transportation industry, the driving speed of the automobile is greatly increased, the performance of the vehicle is also continuously improved and the pursuit of economic benefits in the transportation industry, the conditions of use of tires have undergone major changes. Under the condition of high speed and continuous driving, Traditional tire designs are not adequate due to: [0004] 1. The existing UHP tire groove bottom arc is designed to translate the crown arc, and the transition zone from the middle part of the groo...
