225/45zr1794w purchased at discount tire. TPMS system failed after tire installation. I told the technician and he reset the system. Five miles later TPMS indicator came on. Malfunction TPMS. I monitor the tire pressure periodically and the tires seemed fine. While driving on Florida 528 to the airport i heard a rumbling and pulled over immediately. The tire sidewall was cut almost all the way around the tire. I assume from low pressure or tire malfunction. The tire is only a few months old. I am going to visit discount tire today and see what they say/do. I commute 150 miles a day at highway speeds. Fortunately I was able to pull over and not damage my rim. I removed the tire and put the spare on. I was flying to Columbia south America and nearly missed my flight. I have not found any reason the tire lost air pressure. Because this tire was nearly new it should have held air. Had discount tire fully corrected the TPMS system i may have been able to save the tire and not experienced the horrid experience of changing the tire on the highway 70 mph speed limit however the actual speeds are from 80mph up. Fortunately i work for the Orlando international Airport and had a colleague park my car to avoid missing the flight. Had four road hugger ties on my Audi now 3 and a spare. I'm not sure what the outcome will be but a brand new tire should not have deflated an had discount tire performed as professional technicians i most likely would not be contacting your organization.

The contact owns a 2010 Audi A3 equipped with Bridgestone potenza tires, tire size 225/14/18. While driving approximately 15 mph approaching a stop signal, the contact observed that the tire pressure indicator displayed a low pressure reading. Immediately, the vehicle was driven to the side of the road. The rear driver side tire had slightly flattened; and replaced with the spare tire. The vehicle was taken to the dealer where they referred him to a tire center for the tire diagnosis. The tire center informed that the tire shredded from the tire rim. Also, the other three tires were not road worthy and the sidewall had bubbles. The vehicle was inoperable. The contact stated the defect was not covered under the warranty. The failure mileage was 9,600. The dot number was ejt70ccj3109.
