2007 FORD FIVE HUNDRED Tires Problems

I RECENTLY RAN INTO A MAJOR ISSUE WITH MY 2007 FORD FIVE HUNDRED WHICH REALLY SCARED ME. I WAS ROTATING THE TIRES ON THE CAR AND WHEN I WAS REMOVING THE WHEEL FROM THE DRIVERS SIDE OF THE CAR I NOTICED THAT THE WHEEL WOBBLED BACK AND FORTH. AT FIRST I THOUGHT THIS WAS JUST A BAD BALL JOINT AND PURCHASED A NEW ONE TO REPLACE IT. WHEN I STARTED TO REMOVE THE FACTORY INSTALLED BALL JOINT I NOTICED THAT THE NUT THAT HOLDS THE BALL JOINT TO THE LOWER CONNECTION JOINT WAS ON THE VERGE OF COMING OFF. I FIND THIS VERY DISTURBING AS I LIVE IN A VERY MOUNTAINOUS STATE WITH MANY CURVY ROADS AND STEEP DROP OFFS. HAD THIS NUT FINISHED COMING OFF WHILE ON ONE OF THESE ROADS I MAY NOT BE WRITING THIS LETTER. I WILL ALSO CONTACT NAFTA ABOUT THIS SITUATION AS IT MAY...

2007 FORD FIVE HUNDRED TIRES ARE CRACKING, LOCAL TIRE DEALER SAYS IT SHOULDN'T BE A PROBLEM....SAFETY IS NOT THEIR FIRST CONCERN I GUESS. HE SAYS THE PIRELLI P6 TIRES THAT ARE OEM ONLY HAVE 50,000 MILE RATING TO THEM, I HAVE 37,000 MILES AND THEY ARE ROTTING. TIRES KEEP GOING LOW. *TR

HAVE 2007 FORD 500 HAD A FLAT TIRE ON RT. REAR. TOOK CAR TO DEALER TO FIX. THEY SAID IT WAS CAUSED BY A CRACKED WHEEL. POSSIBLY HITTING BUMP IN ROAD. IT HAS 18444 MILES RARELY DRIVEN AND HAS NEVER HIT A BUMP VERY HARD OR AT ALL. BUMPER TO BUMPER WILL NOT COVER THE COST, AND WE BELIEVE THIS IS A FAULTY WHEEL FROM FACTORY. PLEASE HELP. *TR
