This morning, I got into the car. The TPMS was beeping and flashing about left front tyre. The tyre showed 29 lbs pressure, but the Leakage ICON was flashing.
I have set the TPMS for warning if pressure goes under 28 lbs.
So before going to the office, I got the tyre checked. Took off the tyre and inflated it to 45 lbs pressure and checked in water .. no leakage was detected. Anyways, got the tyre installed and inflated all tyres to 31 lbs (the tyres were warm, so 31 lbs means 29 or 30 lbs cold air pressure).
