2010 MAZDA CX-7 Tires Problems

MY 2010 MAZDA CX7 HAS BEEN IN DIRE NEED OF NEW TIRES. I HAVE HAD SEVERAL REPAIRS FROM PUNCTURES IN THE TIRES WHICH ARE BRIDGESTONE DUELER 215/70R17 WHICH IS MY UNDERSTANDING THAT THEY ARE SOFT TIRES AND THE RATING IS NOT THAT GREAT ON THIS TYPE OF TIRE BUT IT IS THE ONLY TIRE RECOMMENDED FOR THIS MODEL. THIS IS THE ONLY TIRE RECOMMENDED THROUGH MAZDA. THEY ARE ALSO EXPENSIVE. I AM VERY UPSET THAT MAZDA GIVES NO ALLOWANCE OF THE BRAND TIRE THAT A CONSUMER MAY CHOOSE. EVEN THE MAZDA DEALER THAT I BOUGHT FROM DIDN'T HAVE THEM IN STOCK. I FEEL THIS HAS BEEN MISREPRESENTATION ON THE DEALER'S PART AND MAZDA. I HAVE BEEN READING FORUMS OF THIS PROBLEM AND IT IS RECOMMENDED TO REPLACE EVERY YEAR BECAUSE OF TYPE OF TIRE. I LIVE IN FLORIDA AND DO NOT NEED WINTER TIRES. IS THERE ANYTHING I CAN DO?...

WHILE ON INTERSTATE THE TIRE PRESSURE SENSOR ILLUMINATED. HUSBAND CHECKED ALL TIRES AND DISCOVERED THAT ONE OF THE VALVE STEMS WAS BROKEN. THE OUTSIDE WAS CORRODED. THE SLIGHTEST PRESSURE ON IT WAS RELEASING AIR AT A RAPID RATE. WE HAD ONLY JUST PURCHASED THE CAR A WEEK BEFORE. HOW THIS WAS NOT CAUGHT BY THE SERVICE DEPARTMENT AT THE DEALERSHIP IS BEYOND ME. THE DEALERSHIP REPLACED THE STEM, BUT WE WERE TOLD THAT THIS IS A COMMON PROBLEM. REALLY? THEN WHY AREN'T THERE ANY RECALLS ON THIS? AFTER READING THE OTHER NUMEROUS COMPLAINTS ABOUT OUR MODEL, I AM BECOMING INCREASINGLY NERVOUS OVER OUR HASTY PURCHASE. RESEARCH IS KEY IN CHOOSING A VEHICLE. *TR
