Aircraft
Normal; landing with nice touchdown and no side loads. Departed the runway at the high speed at approximately 40-45 kts. Let the aircraft slow on its own while going up the hill toward XX. Made the turn onto XX at approximately 10 kts; then held short [taxiway] for another aircraft. Made the left onto [taxiway] and continued the taxi holding short of [taxiway] for another aircraft. Taxied approximately another 20 ft. when we felt the right side suddenly drop slightly then a very rough ride then stopped immediately suspecting a flat tire (felt like hitting a large pot hole followed by a blow out in a car). Told Ground Control that we suspected a flat tire and asked if they could see anything. They said they could not. The FO (First Officer) opened his window and looked back confirming a flat. Ground Control called emergency vehicles and we set up maintenance and operations services to offload passengers and get the aircraft fixed. The landing and taxi evolution were absolutely uneventful until the second tire went flat. The landing was great; side-loads were not excessive; taxi speed was well within limits; and there was nothing to indicate a problem. Looking at the pictures that we took; I suspect some kind of internal damage from a manufacturers defect of one of the tires that finally gave way either on landing or taxi (possibly rounding a turn); which lead to the second tire taking the entire load of the truck and the brakes on that side leading to excessive heat and fuse plugs melting. The tire appears to have failed in the direction of internal tire plys. Just a guess; but I'm no tire engineer.
B737 Captain reported two tires failed during taxi.
