2010 MAZDA MAZDA3 Wheels Problems

SPONTANEOUS FAILURE OF TIRE VALVE STEM RESULTING IN THE NEAR INSTANTANEOUS DECOMPRESSION OF THE REAR DRIVER'S SIDE TIRE. AT THE TIME I WAS ATTEMPTING TO CHECK THE TIRE PRESSURE OF THAT WHEEL. THE STEM SEPARATED INTO TWO PIECES WITHOUT ANY PRIOR INDICATION OF WEAR. *TR

THE VALVE STEM OF MY TIRE PRESSURE MONITORING SYSTEM (TPMS) HAD SIGNIFICANT CORROSION LEADING TO IMMEDIATE AND RAPID DEFLATION OF FRONT LEFT TIRE WHILE REMOVING AIR HOSE WHILE TENDING TO TPMS WARNING LIGHT. THE RAPID DEFLATION WAS DUE TO COMPLETE AND IMMEDIATE SEVERANCE WHERE THE THREADED PORTION OF VALVE STEM MET VALVE CAP WITHOUT ANY TORQUE OR ABNORMAL PRESSURE APPLIED. THE SEVERED EDGE OF THE VALVE STEM SHOWS CLEAR EVIDENCE OF CORROSION 360 DEGREES AND INWARD, WITH A THIN HALO (APPX. 1/10 OF THE WALL) REMAINING. BOTH THE TIRE AND VALVE STEM SHOWED NO SIGN OF LEAKING AND HELD PROPER PRESSURE WHILE FILLING TO RECOMMENDED PRESSURE UNTIL REMOVAL OF AIR HOSE CAUSED THE STEM TO SPLIT HORIZONTALLY BETWEEN THE 9TH AND 10TH THREAD. PLASTIC VALVE CAPS WERE IN PLACE ON ALL 4 TIRES. SPARE TIRE ALSO NOT ABLE TO BE PUT IN PLACE DUE TO 'STUCK' LUG NUTS ON SAME...

THERE HAS NOT BEEN A FAILURE TO DATE, HOWEVER, ADDING MY VEHICLE TO THE OTHER MAZDA3'S IN THE DATA BASE WHERE THE DESIGN OF THE VEHICLE IS CREATING UNEVEN TIRE WEAR. AS I HAVE READ IN NO LESS THAN 5 BLOGS, THE MANUFACTURER INTENTIONALLY CAMBERS THE REAR TIRES TO INCREASE THE PERFORMANCE AND HANDLING AND UPON NORMAL ROTATION OF THE TIRES, A "BUMPING" NOISE CAN BE HEARD AND FELT. THE TIRE MANUFACTURER WILL DO NOTHING AND STATES IS A DESIGN ISSUE AND MAZDA STATES I MUST DEAL WITH THE TIRE MANUFACTURER. THIS UNEVEN TIRE WEAR AND VIBRATION COULD LEAD TO ADDITIONAL TIRE WEAR AS NOTED BY OTHER OWNERS. AT 11,000 MILES, I SHOULD NOT BE FACED WITH REPLACING THE TIRES.
