The full size Chevy Malibu I rented had one tire with low air pressure before I left the Alamo lot at Mesa Gateway Airport. I should have asked for another car before leaving, but the low tire was at 30 psi versus 38 psi for the other three. However, the next morning, the air pressure was down to 18 psi. I called for roadside assistance, which was a nightmare of automated phone menus and then an unhelpful clerk. I called the Alamo office at the airport, and they sent a replacement car which I appreciated and which performed properly for the rest of my stay.
