B737 First Officer reported being notified after pulling into the gate of a left main tire fire. Airport CFR were called and the passengers deplaned normally.

Narrative

After an uneventful stabilized ILS approach and landing at ZZZ on Runway XXR ; the aircraft was taxied back to the Gate to deplane the passengers. After blocking in and completing the Parking Checklist; the Captain noticed the ground staff were using hand signals to indicate a fire under the aircraft. Both flight deck windows were opened momentarily to communicate with the Ramp Crew who explained there had been a fire on the left main landing gear/tire assembly. The fire had extinguished; but the assembly was still smoking. They confirmed that Crash Fire Rescue had been called and was on their way. The Capt instructed the Flight Attendants to deplane the passengers in an orderly manner using the main passenger door; but leave the other exits armed. The CFR team were at the aircraft approximately 1 min later and I witnessed the Fire Captain take a brief from the Ramp Lead. As the Pilot Flying; the final approach and landing were uneventful; with Autobrakes 3 preselected for the wet Runway. The approach was stabilized throughout. The winds were light; approx 5 kts. crosswind; with a normal touchdown on the centreline. Autobrakes were felt to apply in a symmetrical way and; in conjunction with thrust reverse; the aircraft was slowed. Control of the aircraft was passed to the Captain at 80 kts. and was taxied back to the Gate using routine braking commensurate with SOP taxiing procedures. The first indication that there was a brake fire was when the Ramp Crew signaled to the flight deck at the Gate. At no point did braking; either auto or manual; seem unusual or excessive.
