Device for monitoring, maintenance and/or adjustment of pressure in a tire. The device consisting of the chamber ( 1 ) with shape memory deformable for the period of application of external mechanical forces when the tire rolls on the road surface, connected valve ( 3 ) with the inside space ( 6 ) of the tire ( 2 ) and valve ( 4 ) with the outside environment ( 5 ) according to the invention is based on the principle, that at least one wall of the chamber ( 1 ) is adjacent to the inside wall of the tire ( 2 ) or is a part of the inside wall of the tire ( 2 ). Further device operating on the peristaltic pump principle consisting of the chamber, which is deformable up to the zero cross section according to the invention is based on the principle, that at least one chamber ( 1 ) with block ( 10 ) with shape memory is freely open at one end and equipped with at least one valve at the other end or next to it. The minimum volume of the part of the chamber ( 1 ) at the end equipped with the internal valve ( 3 ) or external valve ( 4 ) is from 1 to 80% of the total maximum volume of the chamber ( 1 ).
