Tire Sidewall problems of the 1997 Ford E-350

Michelin, ltxa/s, p22575/r16 after market 3000, ambulance, right front interior sidewall blewout while driving, causing damage to rim. Manufacturer has been notified, three people were injured.

This is the third set of firestone tires I've had, all on new vehicles, and the third failure of this type (tread separation). I replaced the previous sets at my own expense. I replaced all four rear tires after this recent failure. Upon inspection, a second tire was found to have two bulges in the sidewall. I contacted a local servicing shop who said I could only get an adjustment against another firestone tire. Unacceptable. ( dot number: unk tire size: 22570r16 ).

2 tires blew out with very little tred wear on them. Both times the sidewalls ripped away at sidewall. (tiresize: 16)( dot number: tire size: 16 ).
