2017 MAZDA MAZDA6 Wheels Problems

I PURCHASED A 2017 MAZDA 6 GRAND TOURING IN JULY 2017, NEW FROM CLASSIC MAZDA IN MENTOR, OHIO. THE DUNLOP TIRES THAT CAME ON MY CARE ARE COMPLETE GARBAGE AND UNSUITABLE TO DRIVE ON IN THE RAIN. THEY BEGIN TO HYDROPLANE WITH EVEN THE SLIGHTEST AMOUNT OF WATER ON THE ROAD, AND ARE DOWN RIGHT DANGEROUS IN ANY WEATHER MORE SEVERE THAN LIGHT RAIN. THERE HAVE BEEN DOZENS OF INSTANCES OF WHITE-KNUCKLE DRIVING 10-15MPH SLOWER THAN THE REST OF TRAFFIC BECAUSE THE CAR BECOMES UNDERIVABLE IN THE RAIN. I HAVE NEVER DRIVEN A VEHICLE OR TIRES THAT PERFORMED THIS POORLY NOR HAD SUCH A STARK TRANSITION FROM FEELING PLANTED AND CONFIDENCE INSPIRING IN THE DRY TO SLIDING OFF THE ROAD WHEN IT RAINS. THESE TIRES ARE GOING TO GET ME INJURED OR KILLED! AS BAD AS THEY ARE BRAND NEW ON A BRAND NEW CAR, I SHUDDER TO THINK WHAT...
