New delta Sierra dial tires purchased 06-04-04 for professional delivery vehicle. At 4,644 miles right rear tire tread totally separated while in route with client on freeway causing loss of control of vehicle, blowout, and extensive damage (approx $4,000) to livery vehicle. Yokohama tire Corp asked for tire and denied liability although offered "good will" offer of $2,000 within days. Product liability manager anne stott indicated a road hazard caused separation, not defect, and said a rock the size of her hand could have caused this. Husband kevin burns is only driver of vehicle and never recalled any such hazard or incident. His driving record is impeccable (over 35 years, professional driver total of 12 years) and kevin takes exceptional care of his vehicles. If only a rock like Ms. Stott said did this we feel there is a serious lack of quality control in manufacturer's standards. There are other such complaints in file. If it were not for kevin's excellent driving skills (per client inside vehicle during incident) there most certainly would have been a serious accident with injuries. Collision center manager expressed concern to replace remaining 3 delta sierradial tires on car due to safety issues especially as we carry people for hire in our business.
