Aircraft; Procedure; Human Factors
After initial takeoff from ZZZ; departure notified the crew that ZZZ Tower found a tire and suspected Aircraft X had blown a tire either during taxi or takeoff. The crew had already raised the gear and flaps normally with no indication and decided to continue to ZZZ1. En route; the crew ran all appropriate checklists and decided to conduct a low approach for visual confirmation of landing gear status. The crew conducted a low pass at 500 ft. AGL and ZZZ1 Tower indicated that both tires on the right main landing gear appeared to be missing. The crew climbed to a safe altitude and made the decision to [advise ATC] and divert to ZZZ2 due to runway considerations. ZZZ2 offered a longer; wider runway. The crew briefed and flew the approach to Runway XX and elected to land on the left side of the runway to keep the drag in the center and reduce the chances of departing the runway. The crew landed on the left then maintained centerline due to the drag. The crew stopped the aircraft on the runway and egressed normally.The brakes on Aircraft X had been changed [five days prior]. The brakes appeared to be stiff throughout the trip with a noticeable pull to the right.
After takeoff from ZZZ; while enroute To ZZZ1; Departure Control advised us that ZZZ Tower had told them we may have lost a tire during takeoff. We continued to ZZZ1 airport; assessed the situation; [advised ATC]; and advised the company.At ZZZ1 we flew a low pass; at 500 ft. AGL; with the plane fully configured; to allow Tower personnel to be able to see the status of our landing gear. They advised us that both wheels appeared to be missing. We inquired if he saw any wheels and he said only on one side. I had him confirm that the right side didn't appear to have wheels. We took delay vectors to reassess our situation. Decided to divert to ZZZ2 instead of ZZZ3 due to the volume of traffic at ZZZ3 vs ZZZ2. ZZZ2 has 12;000 ft. runways and good ARRF (Aircraft Rescue and Fire Fighting) support. We briefed the approach; the plan for a smooth touchdown; how to control the aircraft as the right side touched down; and we briefed the evacuation plan and reviewed that checklist in the QRH. Touchdown was smooth with good heading control. I was the pilot not flying and I elected to have [First Officer] execute the landing. He landed according to our briefed plan; left of the centerline (as briefed). [First Officer was able to maintain good heading control bringing the aircraft to a full stop on the centerline. Once stopped; ARRF approached the airplane; established communications with us; did a visual inspection for any possible fires or other visible hazards. As ARRF was inspecting the airplane [First Officer] secured the engines; we completed a normal shutdown and exited the airplane.
Flight crew reported both right hand main tire and wheel assemblies fell off the aircraft at take off.
