NHTSA Complaint #11517880 — 2017 TOYOTA PRIUS PRIME

It was time to replace my original equipment tires after approximately 30,000 miles (41,622 car miles, remainder 11,622 on separate snow tires). The car rode smoothly. I purchased four YOKOHAMA AVID Ascend LX SIZE 195/65R15 tires. The tires were balanced professionally at VIP Tires in Watertown, MA. Since the original tires had a little bit of uneven wear, I also had the car aligned at the same time. I immediately noticed intense vibration in the car seat and floorboard (not in stearing) when driving over 47 mph. I brought the car back and they rebalanced the tires. The vibration remained. I took a video of both back tires (both same DOT code) using my GoPro (and wife driving) and found left rear seemed ok, but right rear had abnormal tread movements. I also noticed much more seat vibration at right rear compared to left rear seat. I brought car back to installer and they (Marco & Julio) confirmed the right rear tire is defective.
