Firestone firehawk indy 500 tire failed on sidewall

- Chicago, IL, USA

This letter is in reference to two Michelin Pilot sport A/S 3+ 255/35zr19 96Y tires which both failed within 1,130 miles of each other from identical failures. These two failures were on the interior sidewall of the tires. These two tires were purchased and installed on the same day, September 15, 2016, by a dealer. The car had 104,775 miles on it at the end of this service. On Tuesday, November 21, while driving to Ohio for thanksgiving holiday I experienced a complete failure of the drivers side rear tire (one of the above Pilot sport tires) at highway speed at 121,801 miles. The tire separated from the interior sidewall completely. On December 8, 2017, at 122,934 miles the other Michelin Pilot sport tire from the above set also failed. While in the parking lot I heard the passenger rear tire venting air and it quickly went flat. The interior sidewall hard a large crack circling almost half the tire. These two failures occurred only 1,130 miles apart in the same part of the tire. These two tires had 17,026 and 18,159 miles respectively, far under the warranted life and the typical life. The second failure was acknowledged by Michelin in a case I opened based on an evaluation of the tire by a Michelin authorized dealer. Michelin has not acknowledge the first failure because I no longer have the tire.
