An air compressor mountable to a sidewall of an annular tire cavity, wherein the compressor comprises an air inlet for receiving air to be pumped into the tire cavity and an air outlet for releasing air into the tire cavity. Further, the compressor comprises a double membrane assembly having a first membrane and a second membrane arranged in parallel to the first membrane. A pressure compensation chamber is provided between the first membrane and the second membrane, the pressure compensation chamber being in fluid communication with the tire cavity. Further, an air compression chamber is arranged on a side of the second membrane opposite to the pressure compensation chamber, wherein the compression chamber is in fluid communication with the air inlet and the air outlet. Moreover, a tire comprises the aforementioned compressor.

A pneumatic tire comprises a sidewall, an annular tire cavity, and a hydraulic actuator connected to the sidewall inside the annular tire cavity, wherein the hydraulic actuator has a flexible reservoir for containing a hydraulic fluid, and an opening allowing hydraulic fluid to enter the reservoir and to exit the reservoir. Further, the hydraulic actuator comprises a lever arm connected to the sidewall and holding the flexible reservoir between the lever arm and the sidewall, wherein the lever arm comprises a fluid channel allowing hydraulic fluid to flow from the reservoir through the opening out of the lever arm.
