Went to enterprise and rented a car that had literally 4 leaking tires and they filled them all up to 55 psi before handing the car over. This photo was taken after the 30 minute drive home.
Called and took the car back in for service only to get the same car, same 55 psi on all wheels, and same major leak in the rears. Went to another enterprise location to get a normal car instead 2 days later. Really took me back to my first car, but it’s a lot less fun when it’s not even yours and the “fix” is just dangerous overpressure.
Some rims are slightly wonky, which can also be exacerbated by temperature fluctuations, with the rims getting a bit larger or smaller. I had a problem like this, and used an air compressor plugged into the cigarette-lighter outlet to pump up the tires from time to time.
Yeah, I’ve got my own pump too. Great purchase.
