I HAVE HAD 6 TIRES REPLACED ON THIS VEHICLE DUE TO TIRE SEPARATION. TWO CAUSED BODY DAMAGE CHEVROET REPLACE 2 TIRES UNDER WARRANTY FOR OUT OF ROUND AT APPROX 1000 MILES. (11/2000) I REPLACED THE LEFT FRON APR 18000 MILES WITH NO DAMAGE. THE RT FRONT CAUSE 1200 IN DAMAGE TO THE RT FENDER IN 2002 AND THE RT REAT CAUSE DAMAGE TO THE REAR OUTER FENDER 1500 IN DAMAGE IN APRIL 2004. GENERAL TIRE DID SEND A CHECK TO REPAIR THE DAMAGE IN WHICH I AM THANKFUL. HOWEVER I RECIEVED THE REIMBURSMENT CHECK ON 6/30/04 CLAIM#4117006. I WAS DRIVING HOME 7/1/04 AND NOTICED A VIBRATION AGAIN. ON 7/3/04 I FOUND YET ANOTHER TIRE SEPERATING SEE FILE #75617. I AM VERY UNHAPPY THAT MY VEHICLE IS BEING DAMAGED FROM THESE TIRES LET ALONE THE INCONVEANCED OF TIME FROM WORK AND RENTAL CAR EXPLENCE. I THING CONTENINTAL TIRE SHOULD REPALCE ALL OF THESE TIRES WITH SOME THING ELSE. AS IT SEAMS TO BRING BACK MEMORIES OF AN OTHER COMPANY (FIRESTONE) I AM VERY FORTUNET THAT NO INJURYS HAVE OCURED FROM THESE TIRE CONSERNS.

2000 CHEVY K3500,I HAVE HAD 5 TIRES REPLACED UNDER WARRANTY TREAD SEPERATION. NONE OF THEM HAD THE TREAD COME COMPLETELY OFF DUE TO THE FACT THAT I AM A SHOP FOREMAN/TECHNICIAN WITH 25 YEARS IN THE BUSINESS AND MAINTAIN MY VEHICLE RELIGIOUSLY. PRESSURE WAS ADJUSTED TO 65 FRONT AND REAR WHEN TOWING. 65 FRONT AND 50 REAR WHEN USING AS A DAILY DRIVER. NONE OF THESE TIRES HAD PUNCTURE REPAIRS DURING THIER USE. THEY ALL SEPERATED IN THE EXACT SAME PLACE, THE OUTSIDE TWO ROWS OF TREAD IS WERE IT WOULD START. FRONT OR BACK IT DIDNT MATTER. THE TRUCK WOULD DEVELOPE A VIBRATION AND I WOULD BRING IT IN AND HAVE THE TIRES CHECKED.THEY WERE AMERITRAC 550 AS 245/75R16. I HAVE WITTNESSED MANY TIRES OF THIS SIZE AND BRAND DEVELOPE THE EXACT SAME CONDITION AND MANY OF THEM WILL BLOWOUT AND DAMAGE THE VEHICLES SEVERLY. I FINALLY REPLACED ALL OF THEM WITH A DIFFERENT BRAND BECAUSE I DIDNT FEEL CONFIDENT THAT THEY WERE SAFE TO TRAVEL OUT OF TOWN ON. I RETAINED THE TIRES THAT CAME OFF WITH THE EXCEPTION OF THE ONE THAT HAD SEPERATED FOR THE LAST TIME. I WORK FOR ONE OF THOUSANDS OF GM DEALERS ACROSSED THE COUNTRY AND I AM SHOCKED AT THE NUMBER OF TIRES THAT WE SEE WITH DEFECTS. MY CURRENT POSITION IS SHOPFOREMAN AND YES I AM IN CHARGE OF THE TIRE DEPARTMENT. THE OTHER BRAND THAT I SEE ALOT OF WITH COMPLETE TREAD SEPERATION AND THE TIRE IS STILL HOLDING AIR IS THE FIRESTONE STEELTEX 245/75R16. I AM NOTE SURE HOW ALL THE POLITICS WORK BETWEEN THE TIRE MAN. AND THE AUTO MAN. BUT IT SURE SEEMS THAT ALOT OF THIS MUST BE GOING UNCHECKED BY THE AGENCIES THAT ARE REGULATING DEFECTS. I WRITE AS A CONCERNED CITIZEN.*AK

Official recalls
100V054000 · Steering:linkages:drag:link:connection
Feb 28, 2000
VEHICLE DESCRIPTION: CHASSIS CABS. THE TAPERED HOLE IN THE DRAG LINK END THAT ATTACHES TO THE PITMAN ARM TAPERED BALL STUD MAY BE MACHINED TOO DEEP CAUSING THE HOLE TO BE OVERSIZED. A DRAG LINK WITH AN OVERSIZED HOLE MAY NOT "SEAT" THE PITMAN ARM TAPERED BALL WHEN ASSEMBLED. THIS COULD CAUSE HIGHER THAN NORMAL FRICTION BETWEEN COMPONENTS DURING OPERATION, AND POSSIBLY RESULT IN JOINT SEPARATION OR A BROKEN BALL STUD.
Consequence & remedy
Consequence: IF THE JOINT SEPARATED OR THE BALL STUD BRAKE WHILE THE VEHICLE WAS MOVING, STEERING CONTROL WOULD BE LOST.
Remedy: DEALERS WILL INSPECT THE STEERING LINKAGE ASSEMBLY AND, IF NECESSARY, REPLACE THE DRAG LINK AND THE PITMAN ARM.
