NHTSA Complaint #10192518 — 2005 CHEVROLET COLORADO

I HAD BEEN NOTICING MILD VIBRATION AT HIGHWAY SPEEDS AND MILD PULL DURING BRAKING. I ACCIDENTALLY DISCOVERED I HAD SEVERE INSIDE EDGE TIRE WEAR AFTER ONLY 30,000 MILES ON THE VEHICLE. I WENT ONLINE AND FOUND A TSB RELATING TO THE TIRE WEAR. I BROUGHT THIS TO THE ATTENTION OF MY DEALER, WHO REPLACED THE FRONT TIRES AND ADJUSTED THE "Z" HEIGHT OF THE FRONT SUSPENSION. 5,000 MILES LATER, I AGAIN FOUND SEVERE INSIDE EDGE WEAR ON MY FRONT TIRES, WHICH THE DEALERSHIP CLAIMED WAS DUE TO A MISALIGNMENT WHICH THEY ADJUSTED. RECENT INSPECTION OF MY TIRES AGAIN SHOWED CONTINUED, SEVERE, INSIDE TIRE WEAR, AT 46000 MILES. OBVIOUSLY, THE DEALERSHIP AND MANUFACTURER HAVE NOT ACTED STRONGLY ENOUGH TO CORRECT THE PROBLEM. HAD I NOT ACCIDENTALLY DISCOVERED THE TIRE WEAR WHEN I DID, I MIGHT OF HAD A FRONT END BLOWOUT AT HIGHWAY SPEEDS
