Open the full vehicle complaint log (all categories)Tire model is: Hankook Ventus S1 Evo Z 225/35R18 87Y. Failure started when vehicle turned the "CHECK TIRE PRESSURE" alert on while driving. Pressure started to drop from 32 lbs to 16 lbs in about 15 minutes. Worth to note: no pot hole or any other object was hit during the day of the incident; or even previous days. After stopping, I noticed that the failure occurred in the inner face of the tire. Inner face was pretty degraded and inner treads were visible. A 15 inch long breakage line was visible. Car has 18k miles on it. When comparing the tire that failed to the rest, its degradation was much higher.
