Aircraft
I set up for the visual to Runway XX backed up with the ILS into ZZZ. The approach met stable approach criteria and landed at approximately 85 knots. Upon landing with all three gear down; the left gear began shaking. I assumed I had a flat tire as we started to drift left slightly. I applied brakes and right rudder; neither of which rectified the situation. The aircraft then continued to roll off to the left of the runway. We hit the grass and the gear caught and we spun around 180 degrees. I notified ATC and shut down the engines. I then called company to inform them that I was off the runway and needed the FBO to bring their passenger van. I asked the passengers if they were okay and explained I thought we had a flat tire. A passenger then informed me my left tire was on the runway about 500 feet further down. I helped the passengers get off the aircraft and told them to stay behind the wing. They all said they were uninjured and were brought to the Gate XX where our agents met them. I stayed with the aircraft and got in contact with Maintenance. When I returned to the terminal I wrote up the aircraft for the tire coming off and the aircraft departing paved surface. I was asked to go back and take more photos of the tire. FBO mechanics came awhile later and were able to get a spare tire on. They said half of the rim was missing so operations and fire went back to the landing spot where they found part of the rim and a handful of pieces of the landing gear all over the runway. The aircraft was towed to the hangar and I left the pieces with the log book with operations in ZZZ.
Pilot reported a runway excursion after the left hand main tire and wheel assembly failed.
