International Classification:

B60C 11/12
B60C 11/03

US Classification:

15220918

Abstract:

Particular embodiments of the present invention include a multi-stage tire tread having a plurality of wear layers, each said layer being located at a different depth of the tire tread, the tread including one or more tread elements including a contact surface and having a first wear layer and a second wear layer, wherein the second wear layer is located below the first wear layer. The tire tread also includes a longitudinal groove extending in a longitudinal direction within the second wear layer of the tread element, wherein said longitudinal groove becomes exposed after a depth of the first wear layer has been worn. The tire tread further includes one or more lateral grooves extending from the longitudinal groove in a lateral direction within the second wear layer of the tread element. The invention also provides a mold element for forming portions of the multi-stage tread.

US Classification:

700 98, 264400, 264 401, 703 1

Abstract:

Tires in use wear in a host of ways. One negative manner in which tires, especially truck tires, may wear is in an irregular fashion. When this phenomenon happens, the tread of the tire may become unusable, forcing the user to replace the tire, which is undesirable. This patent application poses a new and useful way of preventing irregular wear involving the addition of a predetermined configuration of pipes, increasing the useful life of the tire tread.

Abstract:

Tires in use wear in a host of ways. One negative manner in which tires, especially truck tires, may wear is in an irregular fashion. When this phenomenon happens, the tread of the tire may become unusable, forcing the user to replace the tire, which is undesirable. This patent application poses a new and useful way of preventing irregular wear involving the use of hidden sipes or tread blocks. In some embodiments, these hidden sipes or tread blocks are found in tread blocks or ribs adjacent other tread blocks or ribs that have been determined to be susceptible to irregular wear. In other embodiments, the hidden sipes or tread blocks are formed by a sipe blade that has a connecting member to which two y-branched members are attached, and further comprising dividing members that connect between the y-branched members.

B60C 11/03

Abstract:

A tread () for a heavy truck tire is provided that has a bottom surface (), a shoulder rib (), and a sacrificial rib () located outboard from the shoulder rib () in a width direction. A decoupling void () is located between the shoulder rib () and the sacrificial rib (). A decoupling void sipe () is in the shoulder rib () and opens at the shoulder rib upper surface () and at the decoupling void (). The decoupling void sipe () extends in the thickness direction and is closer to the bottom surface () than the decoupling void () in the thickness direction.

International Classification:

B60C 11/12

Abstract:

The present invention provides for a heavy truck tire tread () with a plurality of sipes () in the shoulder rib () that extend from the shoulder edge () to the shoulder groove (). Each one of the sipes () has a bottom () with a teardrop () located at the bottom, and the bottom () does not extend the same depth in the thickness direction across the entire lateral length of the sipe (). The bottom () at a middle of the sipe () extends for less of a depth in the thickness direction than does the bottom () at a shoulder edge () portion of the sipe () located outboard from the middle of the sipe () in the lateral direction. The bottom () at the middle of the sipe () extends for less of a depth in the thickness direction than does the bottom () at a shoulder groove () portion of the sipe () located inboard from the middle of the sipe () in the lateral direction.
