blown out tires and people were wondering why this was happening? Well the ingenious minds at Lexus decided to put in a sensor in their cars (including mine) indicating a driver of a low tire when the pressure went down below a certain level. Well for the better part of three months my light would come on and I would go see my Lexus guy and they would do the vodoo which they do and I would be on my way. Three weeks ago it happened again, so I did my routine and I drove away. (when we got back from our cruise)Just recently (the other day) light came back on, so I emailed my guy and he says maybe I have a slow leak in the tire. My question is do I replace all four tires and start fresh with a new set so this would happen less frequently or do I keep the four and have them inspect all four for leaks, and the whole ball of wax?
