Abstract

The invention discloses a high-performance low-rolling-resistance, structurally comprising a tire body, tire shoulders, a crown, vertical grooves, first radiating blade grooves and connection grooves;a tire pattern employs the four vertical grooves peripherally arranged as main pattern grooves which are 15 mm in depth; the bottoms of the vertical grooves are of smooth transition, so that stress concentration is avoided; the edge of each pattern piece is evenly provided with radiating blade grooves 12 mm in depth and communicated with the pattern main grooves; heat generated by the tire duringuse can be effectively decreased, early damage of the tire is prevented, and the service life of the tire is extended; an oblique transverse connection groove 59 degrees angled to two vertical grooves is arranged between the two vertical grooves; the crown pattern piece is divided into wedged pattern pieces, so that good overall rigidity of the pattern piece is guaranteed, rolling resistance is decreased, grip of the tire can be improved, and good operability is provided.

Description

technical field [0001] The invention is a high-performance low-rolling-resistance tire, which belongs to the field of automobile tires. Background technique [0002] In recent years, due to the increasing popularity of automobiles, people have paid more and more attention to the pollution of automobile exhaust to the environment. Coupled with the increasing shortage of oil resources, the fuel economy and exhaust emissions of the automobile industry have received unprecedented attention. Experimental statistics, 10% to 30% of the fuel consumption of the truck during driving comes from the rolling energy loss of the tires. And the rolling resistance of the tire is reduced by 10%, and the car will save fuel by 2-4%. Therefore, reducing the rolling resistance of tires can save vehicle fuel on the one hand, and reduce exhaust emissions on the other hand, thereby protecting the environment. The rolling resistance of truck tires is affected by factors such as its structure, weight...
