2003 HYUNDAI SONATA Tiresvalve Problems

I AM EXPERIENCING THE VALVE STEM/TIRE ISSUES IN MY 2003 HYUNDAI SONATA THAT ARE CURRENTLY BEING INVESTIGATED. I HAVE HAD 2 FLAT TIRES SINCE JULY AND BOTH TIMES I WAS TOLD THAT IT WAS THE VALVE STEM. I WAS TOLD THAT THIS IS A HYUNDAI ISSUE AND THAT WHEN YOU HIT A BUMP THE HUBCAP SPINS AND EVENTUALLY "SNAPS" OFF THE VALVE STEM. I HAVE CALLED 2 DIFFERENT HYUNDAI DEALERSHIPS AND THEY BOTH DENIED THAT IT WAS A HYUNDAI ISSUE. THEY BOTH CLAIMED THAT I PROBABLY HAVE THE WRONG SIZE TIRE ON THE CAR. I FELT LIKE MY ISSUE WAS DISMISSED BOTH TIMES. THE TIRES ON THE CAR ARE THE EXACT SIZE AS REFERENCED IN MY OWNERS MANUAL. I WAS TOLD THAT REPLACING THE TIRES TO A "SPECIFIC BRAND" WOULD SOLVE THE PROBLEM. SO YESTERDAY, I BOUGHT 2 NEW TIRES AFTER I COULD NO LONGER KEEP AIR IN THE FRONT...

HUBCAPS ON 2003 SONATA SLIDE AROUND PINCHING VALVE STEMS. THIS WAS FIRST NOTICED WHEN I REPLACED TIRES FROM MICHELIN TO BF GOODRICH . TIRES ARE PROPER SIZE .THIS PROBLEM OF THE HUBCAPS SHIFTING HAPPENS DAILY AS I HAVE TO REMOVE HUBCAPS AND STRAIGHTEN. HAVE NOW REMOVED HUBCAPS PERMANENTLY FOR SAFETY REASONS. HAVE HAD ONE BLOW-OUT DUE TO STEM BEING TWISTED. NUMBER OF FAILURES BELOW ARE ESTIMATED BUT THE HUBCAPS UNTIL RECENTLY WERE OUT OF POSITION DAILY. DATE OF BLOW-OUT BELOW IS ESTIMATED SOMEONE AROUND THE MIDDLE OF AUGUST. *JB

ON 03/26/05, I PURCHASED BF GOODRICH TOURING T/A PRO SERIES (SIZE P205/65R15) FOR MY 2003 SONATA AT SAM'S CLUB. IN A MONTH AND A HALF, I HAD 4 FLAT TIRES AND 10 VALVES REPLACED BECAUSE THE HUB CAPS SPIN AND SLICE THE VALVES. I LOST 7.5 HOURS OF WORK AND RECEIVED A BACK INJURY WHILE TRYING TO CHANGE ONE OF THE TIRES. I'VE SPOKEN TO HYUNDAI AND BF GOODRICH - BOTH OF WHICH SUGGESTED GETTING THE H RATED TIRES INSTEAD OF THE S RATED. I DID THAT, BUT IT DIDN'T WORK. I ALSO PAID $75 FOR A DIAGNOSTICIAN TO TELL ME THAT I HAD THE WRONG BEAD ON THE TIRES BUT WHOM COULDN'T SUGGEST A SOLUTION. MY OWNERS MANUAL SIMPLY STATES, ALWAYS REPLACE YOUR TIRES WITH THOSE OF THE RECOMMENDED SIZE LISTS THE TIRE SIZE SPECIFICATIONS AS P 205/65R15. THERE IS NO RECOMMENDED REPLACEMENT BRAND NAMED AND NO MENTION ABOUT...
