The NTSB's narrative final · quoted from the NTSB record
The private pilot was landing a tailwheel airplane equipped with oversized main tires on a warm asphalt runway. He reported that during the landing roll, the airplane lurched to the right, and he was unable to regain directional control. The airplane subsequently struck the left wing and propeller on the runway, and came to a rest nose down on the runway. The pilot stated the tailwheel airplane was equipped with oversized tires, and that the combination of large tires and warm runway surface may have made the airplane more difficult to control. He also noted that he was unaware of any preaccident mechanical problems with the airplane.
