Abstract: The tread has a total width W and two main grooves. The main grooves divide the tread into a middle region and edge regions. The middle region has an axial width Lm that is 45% to 70% of the total width W. The volume void ratio of the tread when new is less than 17%. An internal surface extends parallel to the tread surface when new and is in contact radially with the innermost points of the deepest main grooves. The middle part has a plurality of transverse sipes, each of which has a depth at least equal to the depth of the main grooves. The transverse sipes open into the main grooves. The middle region has a volume void ratio when new that is less than half the total volume void ratio of the tread, and at least one circumferential channel appears when the tread becomes part worn.

Abstract: The tire tread presents a thickness T20 and a sipe (30) having a length and a depth d3o extending into the tread thickness in a direction away from an outer, ground-engaging side of the tread. The sipe articulates between an open configuration and a closed configuration as the tire rotates during tire operation. The sipe has a variable-width W30 extending transverse to the sipe length and transverse to the depth in the open configuration, the variable-width being defined by a pair of opposing sipe sides (34). The variable-width decreases as the depth increases into the tread thickness in a direction away from the outer, ground-engaging side. The opposing sipe sides substantially engage each other at substantially the same time in the closed configuration.

Abstract: A system is provided for dynamically reading data from transponders of tires disposed laterally on a same side of a vehicle. The system includes antennas, a sensor for each antenna, a reader, a controllable switch, and a programmable logic controller. The antennas are arranged to receive data transmitted by the transponders. Each sensor is positioned upstream of an effective reading area covered by a corresponding one of the antennas, and each sensor transmits a signal associated with passage of a tire. The reader is arranged to couple to the antennas in order to read and store data from the transponders. The switch is positioned between the antennas and the reader to provide a selective coupling between the reader and each of the antennas. The controller controls the switch as a function of wheel-passage sensor signals.

Abstract: Particular embodiments of the invention concerns methods of forming a retreaded tire with improved tread edge area bonding, and re-treaded tires formed thereby. One embodiment of such methods includes forming an unbonded retreaded tire by arranging a pre-cured tread annularly around an annular tire carcass with a bonding layer arranged there between. The pre-cured tread includes a pair of opposing tread edges laterally-spaced to define a width of the pre-cured tread. The method also includes bonding the tread of the unbonded tire to the tire carcass to form a bonded retreaded tire by sufficiently pressurizing and heating the curing chamber to cure the bonding layer of the unbonded tire, which includes at least partially bonding a pair of laterally-spaced tread edge areas of the pre-cured tread to the tire carcass prior to an intermediate portion of the pre-cured tread located between the pair of laterally-spaced tread edge areas.

Abstract: The present invention relates to a specific functionalized diene elastomer. This functionalized elastomer exhibits a reduced cold flow without, however, damaging the properties of a reinforced rubber composition in which it is present, in particular the processing properties and the hysteresis properties. This functionalized diene elastomer carries, at the chain end, a silanol functional group or a polysiloxane block having a silanol end and is partially coupled by or star-branched by tin.
