NHTSA Complaint #10203271 — 2007 MAZDA CX-7

MAZDA CX7 (FWD) EXHIBITS ABNORMAL TIRE WEAR(CUPPING,FEATHERING) ON ALL (4) TIRES AFTER LESS THAN 1000 MILES. BROUGHT THE CAR INTO THE PURCHASING DEALER WHO RE-BALANCED AND REALIGNED. TIRES CONTINUED TO EXHIBIT THE SAME WEAR AFTER 2000 MILES AND RIDE AT HIGHWAY SPEEDS HAD SOME VIBRATION AND ROUGH FEEL AT LOWER SPEEDS. DEALER ONCE AGAIN REALIGNED VEHICLE AND INCREASED THE PSI ON ALL 4 TIRES TO 36PSI. AT JUST OVER 5000 MILES VEHICLE WAS BROUGHT INTO DEALER AGAIN, STILL CONTINUING TO SHOW ABNORMAL WEAR AND POOR RIDE AT HIGHWAY SPEEDS (VIBRATION & ROUGH). DEALER REALIGNED AND RE-BALANCED ALL WHEELS AND ONCE AGAIN INCREASED TIRE INFLATION TO 36PSI. I LATER CONTACTED THE SERVICE MGR AND TOLD HIM THAT I DID NOT LIKE THE FACT THAT HE INCREASED THE TIRE PRESSURE OVER THE MANUFACTURERS RECOMMENDED SETTINGS AND THAT THIS WOULD CAUSE THE TIRE TO WEAR DOWN THE CENTER QUICKLY. *JB
