Description

Technical Field

[0001] The utility model relates to the technical field of automobile tires, in particular to a pneumatic tire for improving snow performance. Background Art

[0002] Snow tires have the advantages of safe driving, comfort and strong wear resistance on ice and snow roads.

[0021] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, as Figures 1 - 3As shown in the figure, an inflatable tire for improving snow performance includes a tread 1. A number of longitudinal grooves 4 are provided on the tread 1. A number of crown tread blocks 2 are provided on both sides of the longitudinal grooves 4 on the tread 1. A number of shoulder tread blocks 8 are provided on both sides of the crown tread blocks 2 on the tread 1. Pattern grooves 7 are provided on both the crown tread blocks 2 and the shoulder tread blocks 8. Water storage holes 5 are provided on both sides of the pattern grooves 7 on the crown tread blocks 2. Stud holes 6 are provided on both sides of the water storage holes 5. The pattern grooves 7 are beneficial to the rigidity of the tread 1 and continuously provide grip throughout the tire life cycle. The water storage holes 5 can store and eliminate the water in the water film between the tire and the road surface. The stud holes 6 can improve the tire strength and, under the condition of ensuring the tread stiffness, thus improve the snow performance and continuous traction force.

[0023] In one embodiment, as Figure 1 shown, a crown reinforcing rib 3 is provided between the crown tread blocks 2. The reinforcing rib 3 can improve the strength between the crown tread blocks 2 and make them more stable.

[0024] In one embodiment, as Figure 3 shown, the depth of the water storage hole 5 is in the range of 10 - 14 mm, and the width W3 of the water storage hole 5 is in the range of 2 - 4 mm, which can store and eliminate the water in the water film between the tire and the road surface.

[0025] In one embodiment, as Figure 3 shown, the depth of the stud hole 6 is in the range of 10 - 14 mm, and the width W3 of the stud hole 6 is in the range of 2 - 4 mm. The water storage hole 5 can also be used as the stud hole 6 in an extremely cold state to improve the snow wet and slippery performance.

[0026] In one embodiment, as Figure 2 shown, the depth H1 of the pattern groove 7 is in the range of 17 - 21 mm, and the width W1 of the pattern groove is in the range of 8 - 10 mm. The pattern groove 7 is beneficial to the rigidity of the tread 1 and continuously provides grip throughout the tire life cycle.
