PNEUMATIC TIRE
A tire frame member 17 configured from a resin material is formed with plural outer surface recesses 40 on a tire outer surface. The outer surface recesses 40 are disposed separated from each other, and are formed at least on an outer surface of a side portion 14.
SHAPE MEMORY CHAMBER FOR TIRE PRESSURE CONTROL
A peristaltic pump chamber with shape memory for pressure adjustment in tires is provided and which is part of the tire or is adjacent to the tire wall or is a part of a vehicle wheel, in particular for tires with an inner tube, e.g. bicycle tires.
