It was my initial flight in an aircraft I'm looking at purchasing. I was in the left seat with the current owner in the right (without brakes). I did a full stop landing and got on the brakes too hard. Neither the owner nor I felt as though the aircraft was skidding until we started a slight left turn towards the taxiway (approximately 10 kts). The aircraft began to skid at which point I released all pressure on the brake pedals. The aircraft had a slight dropping rolling motion as we stopped on the runway. We both suspected we blew a tire; and tried to taxi clear of Runway XX at [intersection]. The aircraft would not move. The owner got out to confirm and we shut down the aircraft and called for a tug. We confirmed that both tires had rolled off the hubs. The owner had a hand held radio and we were in contact with Tower the entire time even outside the aircraft. 	We discussed the events and I am used to [heavy] type aircraft with antiskid systems. I got on the brakes too hard and blew both main tires. I'll be more careful when slowly applying brakes from here on out and always opt for letting the aircraft roll out to the next taxiway verses trying to get off on the shorter distance.
The mission was a training flight. Following an uneventful flight; upon landing roll out; the student applied too much brake pressure due to his inexperience with this particular airplane. This caused both main wheels to lock and blew both main wheel tires. This incident caused the shutdown of the only runway at that airport while the airplane was towed off the runway.I was instructing a potential buyer for the airplane; who is a personal friend of mine. I occupied the right seat; while the student occupied the left seat. Unfortunately the right seat rudder pedals do not have brakes; only the left seat rudder pedals have brakes in this model aircraft. Therefore I was not able to assist in braking the aircraft during landing roll out. The student has a commercial pilot certificate with single and multi-engine ratings and approximately 2;400 total flying hours. I hold ATP and commercial pilot and instructor certificates with single and multi-engine ratings.
Mooney pilot reported applying excessive braking force due to unfamiliarity with the aircraft; resulting in two blown tires and shutdown of an airport's main runway.
