We landed Runway XXR at ZZZ.  After clearing the runway a taxiing aircraft behind us notified us that we had a flat tire.  The aircraft controls and indications were normal so we continued to the gate.  After arriving we discovered the tire was severely damaged and some parts of under side of wing were damaged.  Maintenance was informed and an AML entry was made in regard to the Number 2 main tire problem.Possibly a faulty tire was installed on the aircraft the night before.  I am not an expert about what causes tires to fail.Suggestions: Maybe a better brand of retread tire should be used on the fleet.
