2007 AUDI A3 Tires Problems

MY 2007 AUDI A3 HAS SEVERE, UNBEARABLE TIRE NOISE REGARDLESS OF MILEAGE ON THE TIRES. I REPLACED MY 1ST SET OF PIRELLI P6 ALL SEASONS WAY BEFORE THEIR TREAD WAS WORN OUT DUE TO THE ROAD NOISE ONLY TO FIND THAT THE NOISE WOULD SOON RETURN AFTER APPROX. 7500 MILES ON THE REPLACEMENT SET. I CANNOT REPLACE TIRES EVERY 7500-10000 MILES. *TR

(1) HOWL, HUM CHOPPING NOISE. BALANCE AND ALIGNMENT WITHIN SPEC PER AUDI DEALERSHIP. (2) EXTREMELY NOISY. UNEVEN WEAR ACROSS EACH TIRE. UNEVEN WEAR TIRE TO TIRE. POOR WEAR AT 10,000 MI (3) SEARS IS THE PIRELLI DEALER IN THIS AREA AND IS THE PARTY RESPONSIBLE FOR TIRE ADJUSTMENTS. THEY (RYAN) STATE THE TIRES ARE WEARING POORLY AND UNEVENLY. THEY CAN'T GET PIRELLI TO PRE-AUTHORIZE THE REPLACEMENTS. IF THEY REPLACE THE TIRES BECAUSE THEY THINK THEY'RE DEFECTIVE, AND PIRELLI BELIEVES THE TIRES ARE NOT DEFECTIVE, SEARS WON'T BE REIMBURSED FOR THE REPLACEMENTS. IT'S REPORTED THAT PIRELLI IS VERY RESISTANT TO REIMBURSEMENT FOR TIRE ADJUSTMENTS. THIS LEAVES THE SEARS IN THE AWKWARD POSITION OF BEING UNABLE TO PROPERLY SERVICE PIRELLI TIRES. I'VE CONTACTED PIRELLI CUSTOMER RELATIONS AND THEY ARE UNWILLING TO EXTEND ANY CONSIDERATION OF MY CLAIM. *JB
