Narrative:

I departed for a routine flight for parachute operations. I contacted [departure] at 3;000 feet MSL. Climbing through 5;000 feet; the chief tandem instructor on board informed me that he could see fluid spraying from underneath the right wing. There were no adverse engine indications; no vibrations; and no fire; so I continued my climb to a safe altitude of 10;000 feet MSL so that I could allow all my skydiving passengers to exit safely.I called approach with my 1-minute routine call and informed them that the passengers would be exiting at an altitude which was lower than our operation routinely dropped. After we were cleared to jump; all passengers exited safely; and I began my routine descent. On landing roll; it felt as though the left main tire may have blown. I ran off the left side of the runway and sustained a propeller strike on the left engine. After shutting down both engines and safely exiting the aircraft; the owner of the skydiving business informed me that the wheel came off of the airplane upon rotation; I had landed the plane and the left strut had dug into the pavement; which caused my loss of control. The fluid that the instructor witnessed at 5;000 feet was perhaps hydraulic fluid from the broken break line. There were no injuries and no damage to the airframe.
