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.
I guess my old car (from 2005) does the same thing. Has no tyre pressure sensors but gave me a tyre pressure fault on time. Turned out my rear left had a small leak. Error light came on at 1.6 bar (rears are supposed to be at 2.1-2.3)
Seems to me it did the job, maybe not as accurate, but it’s a way simpler system and less error prone.
