2017 BMW 230I Wheels Problems

IN THE LAST 12 MONTHS I HAD TO REPLACE 4 RUN FLAT TIRES AT A COST OF APPROXIMATELY $1300. THE TIRE WERE COMING OFF THE CAR, THERE WERE BUBBLES IN THE TIRE. BMW SAID "THAT HAPPENS WITH 2-SERIES CARS." THEY SAID THE LOW PROFILE CAUSES THIS WHEN YOU HIT POTHOLES. I DIDN'T HIT ANY POTHOLES. THE CAR THUMPS WHENEVER IT HITS EVEN THE SMALLEST OF BUMPS. I LIVE IN THE BURBS WHERE THE ROADS ARE RELATIVELY SMOOTH. I HAVE NEVER HAD A PROBLEM LIKE THIS BEFORE WITH THE MANY CARS I LEASED BEFORE. BMW OF MT. KISCO WAS TOTALLING UNCARING AND DID NOT OFFER ANY SOLUTIONS DESPITE THE UNSAFE CONDITIONS, NOT TO MENTION THE COST. I WANT TO GET OUT OF THE LEASE AFTER 1 YEAR OF THE 3 YEARS BUT THEY WOULDN'T EVEN RETURN MY CALL.
