In less than 12 months, we have had 2 "Continental purecontact with ecoplus technology" tires fail in spectacular fashion. Both tires had nearly ripped in half from sidewall to sidewall while driving. 1 of the tires did so after hitting a pothole, while the other did so while at over 50 mph and no visible debris/potholes around. Tires were inflated to around 32 psi, and were between 1 and 2 years old with 80% of tread remaining.
