After landing; left main gear showed abnormal brake temperatures. The outboard brakes were at 400 degrees and increasing while the inboard brakes were at 21 degrees. The right main landing gears showed normal temperatures expected after a normal landing. BRK OVERHEAT and LG NO DISPATCH caution messages populated on EICAS. FO (First Officer) and I discussed it and thought it was most likely was a faulty indication. I asked FO to perform a post flight walk around and report back what he finds. FO came back and said the inboard wheel was missing on the landing gear.
After landing parking at the gate; both pilots noticed that the left main gear outboard brake temp was unusually high to over 450C while inboard brake remained at around 22C. The brake overtemp EICAS msg popped out couple seconds after following with LG no Dispatch message after the flight crew shut down the engine. First Officer noticed right away the left side inboard landing gear the wheel was missing during post flight walk around
Flight Crew reported finding the left hand inboard main tire and wheel assembly missing.
