I bought a tire gauge because of its curved dual head; I first used it on our RV tires. I brought it to our plane, which had been in the hangar since December, waiting for the bad weather to improve with the onset of spring. The aircraft has wheel pants with small doors that open, requiring tire rotation to locate the tire valve stem to check air pressure in a very tight/restricted space. This gauge worked great for checking tire pressures of 49psi for the front tires and 41psi for both main gear tires. Larger readings were also helpful. The sensor is in the airplane hangar now, I will order another sensor for the RV.
