The pilot was landing a tailwheel airplane on a hard surfaced runway. The airplane's main landing gear wheels were equipped with over-sized, 'Tundra' tires. The pilot stated that immediately upon touchdown, the airplane began to veer to the right. He said he sensed a crosswind, and applied left aileron. He applied brakes, and heard the left wing scrapping the runway. When he exited the airplane, he noticed the left main tire was flat, and the left aileron was damaged.
