Abstract: This invention relates generally to an improved design that provides better hydroplaning performance for a tire, and, more specifically, to a tire that has a variable pressure shear band located below its tread that provides increased structural stiffness to the tire, helping the tire to resist deformation when the tire encounters water, thereby decreasing the tendency of the tire to hydroplane. Advantageously, the variable pressure shear band can improve the hydroplaning performance and rolling resistance simultaneously without degrading wear performance.

Abstract: The present invention relates to a diene rubber composition reinforced with an inorganic filler comprising a thermoplastic polymer bearing, at at least one end, a silanol or silyl ether functional group.

The use of such a composition in the inner liner of the tire, including graphite and a non-reinforcing filler of chalk type, makes it possible to notably improve the airtightness properties with respect to a control composition which comprises only graphite and which already performs very well in this aspect, but also with respect to a control composition conventionally used in the inner liners of tires, while maintaining a good level of the stiffness and processability properties as the conventional control compositions.

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.

These data, called RFID data, are stored in the wheel module (22). The wheel module (22) comprises at least one sensor (P) of the pressure of the tyre, and the RFID data stored in the wheel module (22) are erased when the pressure detected by the pressure sensor (P) is less than or equal to a predetermined pressure threshold.
