ALUMINUM WHEELS DENT EASILY ALLOWING AIR LEAKAGE FROM TIRES. THESE ARE THE SPORT WHEELS ON THE JAG X-TYPE MODEL. I RAN OVER A DEER CARCASS IN ROAD AND THE RIGHT FRONT PASSENGER SIDE TIRE DEFLATED AND CAME OFF THE RIM AS THE CAR WAS TRAVELING 70 MPH. THE CAR SPUN OUT OF CONTROL AND $17.000 OF DAMAGE WAS INCURRED. AFTER THE ACCIDENT IT WAS NOTED AT ACTUALLY ALL THE WHEELS HAD SMALL DENTS AND THEY ALL NEEDED TO BE REPLACED. REGULAR TIRES AND WHEELS WERE PURCHASED. TIRES WERE MADE BY CONTINENTAL. ALUMINUM WHEELS WERE STANDARD ON SPORTS MODEL. *JB
