Narrative:

Upon landing at lhr on runway 27L with normal sink rate and a soft touchdown on rollout noticed a bump on use of the left reverser only, right reverser placarded inoperative. Did not realize that anything was wrong until lhr tower told an airplane behind us to go around. Then as we cleared the runway the tower told us to contact the fire trucks on frequency 126.6, and he advised us that smoke had come from our left gear area and it seemed that the #5 tire was deflated. I asked them if there was any visible signs of damage or smoke. They responded no so therefore I elected to proceed to gate XXX and deplane normally. I can only suspect that the anti-skid valve or sensor did not release, therefore causing the tire to be scuffed and become deflated.
