On june 30, 2006, country coach filed defect report 06v-262 stating that the toyo 275/70r22.5m102z tires are defective and could fail unexpectedly causing a loss of vehicle control.odi's investigation found that front tire failures have been caused by country coach's selection of tires that provided marginal load carrying capacity for their intended application.owners were frequently unable to comply with country coach's campaign requirements because these requirements were ineffectively communciated and because specified tire inflation pressures were difficult for owners to achieve and maintain. Odi also found that the rubber properties of the toyo 275/70r22.5 m102z degrade with time. The degradation in rubber properties does not provide any obvious indications to the vehicle owner and the tires become more susceptible to failure over time when subjected to thevehicle operating conditions described above.
