I HAVE EXPERIENCED 4 FRONT TIRE FAILURES WITH THE CONTINENTAL PROCONTACT TX TIRES THAT ARE OEM ON THE 2018 GENESIS G80 SPORT. ALL FAILURES HAVE BEEN AT HIGHWAY SPEED WITH 2 COMPLETE SIDEWALL FAILURES AND 2 BLOWOUTS. IN EACH INSTANCE I HAD NO WARNING AND HAD TO CAREFULLY MOVE TO THE RIGHT SHOULDER. I HAVE BEEN DRIVING OVER 40 YEARS AND HAVE ONLY EXPERIENCED ONE OTHER BLOWOUT. WITH THIS VEHICLE/TIRE COMBINATION I HAVE HAD 4 BLOWOUTS IN 90 DAYS. THE CAR HAS 5,600 MILES ON IT. THESE TIRES ARE UNSAFE AND SHOULD BE RECALLED.
