Had the same problem. Fixed it by replacing the valve extenders. Not only would they not work woth the Pressure Pro, it was difficult to get a reading with a tire guage. Part of the problem on the left rear was I am sure caused by the mud flap in front of teh tires wearing down and striking the valve extender with the piece that fit between the tires. Had them replaced with high quality ones by a Michelin dealer.
