NHTSA Complaint #11173140 — 2005 MAZDA MAZDA3

TIRES FEATHER OR CUP IN LESS THAN 25000 MILES DUE TO THE REAR WHEEL FACTORY CAMBER TIRE MANUFACTURERS DO NOT RECOMMEND AGGRESSIVE CAMBER AND WILL NOT WARRANTY THE TIRES FOR PREMATURE FAILURE. MAZDA AND OTHER MANUFACTURERS KNOW THAT THE AGGRESSIVE CAMBER CAUSES TIRES TO WEAR FASTER SINCE THEY ARE NOT DESIGNED FOR THIS. THE FEATHERING DRASTICALLY AFFECT HANDLING ESPECIALLY IN WET WEATHER. TIRE MANUFACTURERS SHOULD STATE THE MAXIMUM ACCEPTABLE CAMBER FOR THEIR TIRES AND MANUFACTURERS SHOULD CHOOSE APPROPRIATELY DESIGN TIRES FOR THIS APPLICATION. IT IS A SAFETY ISSUE SINCE IT HAPPENS WITH FACTORY RECOMMENDED ALIGNMENT SPECS. THE AGGRESSIVE CAMBER IMPROVES HANDLING BUT TIRES ARE NOT DESIGNED FOR THIS. IF THE TIRE MANUFACTURER WILL NOT BACK THE TIRE FOR THIS APPLICATION THEN THE CAR MANUFACTURER HAS IMPROPERLY DESIGNED THE SUSPENSION FOR PASSENGER CARS. THIS IS THE 3S MODEL WITH ONLY 135000 MILES AND 5TH SET OF TIRES AND ALIGNMENT CHECKED EACH TIME.
