Provided is a pneumatic tire. A sipe includes, on each of a leading side edge and a trailing side edge, a chamfered portion and a non-chamfered region in which no other chamfered portion is present. A maximum depth of the chamfered portion is shallower than a maximum depth of the sipe, and a width of the sipe is substantially constant. In a cross-sectional view perpendicular to a lengthwise direction of the sipe, at least one chamfered portion has a profile line that projects outwards in the radial direction beyond a chamfer reference line connecting the end portions of the chamfered portion, and a cross-sectional area of a chamfered region that is surrounded by the profile line, the sipe, and a tread contact surface of a tread portion is smaller than a cross-sectional area of a reference region surrounded by the chamfer reference line, the sipe, and the tread contact surface.

Methods perform one or more dispatched medical logistics operations using a modular autonomous bot apparatus assembly and a dispatch server where the operations are related to a diagnosis kit for treating a patient. The MAM of the bot receives a dispatch command, verifies compatibility of the bot assembly with the dispatched operation(s), receives a diagnosis kit in the CSS, has the MAM autonomously causing the MB to move to a destination location while notifying the authorized delivery recipient for the diagnosis kit of the approaching delivery. With appropriate authentication input received, the MAM coordinates with the CSS to provide access to the kit, monitor unloading of the kit, provide instructional information on use of the kit, and autonomously cause the MB to return to the original location with a return item related to the diagnosis kit with notification to personnel at the medical entity about the return item.

A pneumatic tire 1 comprises a carcass 6 extending between bead cores of bead portions via a tread portion 2 and sidewall portions, and a belt layer 7 arranged on an outer side in a tire radial direction of the carcass 6 and inside of the tread portion 2. The pneumatic tire 1 further comprises a damping rubber body 30 arranged between the carcass 6 and the belt layer 7, and a noise damper 20 arranged on an inner cavity surface of the tread portion 2. A width W1 in a tire axial direction of the damping rubber body 30 is in a range of from 60% to 130% of a width W2 in the tire axial direction of the belt layer 7, and a water absorption rate of the noise damper 20 is in a range of from 10% to 25%.
