2017 LEXUS NX200T Suspension Problems

AFTER REPLACING TIRES, AT HIGHWAY SPEEDS THE CAR SHAKES. REPLACED THE REPLACEMENT TIRES WITH A DIFFERENT MANUFACTURER AND TREAD TYPE AND STILL HAVE THE SAME VIBRATION AT THE SAME SPEED(S). TIRE PLACE PUT A TOTAL OF 10 TIRES ON THE VEHICLE TO NO AVAIL AND ROAD FORCE BALANCED THE TIRES. RECOMMENDED I TAKE THE VEHICLE TO THE DEALERSHIP. THE LEXUS DEALERSHIP SAID THAT ONLY THE EXACT TIRES THAT CAME ON THE CAR WOULD GUARANTEE THE CAR WOULDN'T SHAKE. THEY ROADFORCE BLANCHED THE SAME TIRES AND CAME UP WITH VASTLY DIFFERENT RESULTS 2 WEEKS APART. WHEN ASKED WHAT WOULD HAPPEN WHEN THE TIRES THAT CAME ON THE VEHICLE WOULD BE DISCONTINUED THERE WAS NO RESPONSE. SO, IN SHORT, LEXUS HAS MADE A VEHICLE THAT, ONCE THE OEM SELECTED TIRES ARE DISCONTINUED, WILL NO LONGER PROVIDE A SMOOTH RIDE.
