Embodiment Construction

[0035] see Figure 1-3, shows a tire 20 having transverse L, circumferential C, and radial R directions having a tread block 22 defined by transverse and circumferential grooves 24 , 26 . These figures also show different patterns of bridges 28 occurring within the lateral grooves 24, said bridges having a split configuration and being spaced a predetermined distance from the bottom surface 30 of the lateral groove 24 and from the top surface 32 of the tread. By introducing rubber or bridges into the transverse grooves 24, the drainage and absorption of water is generally restricted, resulting in a reduced resistance of the tire to hydroplaning, which means that the tire will hydroplan at low speeds. However, with the present invention, an open channel 34 appears below the bridge, which allows water to pass through the transverse grooves during the life of the tire. Accordingly, hydroplaning performance is not adversely affected.

[0036] In a similar manner, a bridge typica...

Abstract

This invention relates generally to tires having treads that have a configuration and / or properties for maintaining hydroplaning resistance and improving rolling resistance, and, more specifically, to a tire that has a tread with bridged areas found in its lateral grooves that are configured to maintain hydroplaning resistance and snow traction while also improving rolling resistance.

Description

technical field [0001] The present invention relates generally to a tire having a tread having configurations and / or properties for maintaining hydroplaning performance and improving rolling resistance, and more particularly, to a tire having a tread having Having bridging areas appearing in its transverse grooves, the bridging areas are configured to maintain hydroplaning performance and snow traction while also improving rolling resistance. Background technique [0002] Due to the increase in fuel prices, reducing the energy consumption of a vehicle when the vehicle is running has become an important goal. In many cases, this requirement has influenced the development of tires, requiring them to consider the issue of rolling resistance. Therefore, tire designers need to design tires with low rolling resistance. Rolling resistance is an indicator of energy loss due to rolling, which in turn leads to heat generation. This lost heat from the tires is an important contribut...
