Concorde needs the anti-burst tires and anti-puncture tanks because its wheels and tires rotate at much higher speed than (most/all) subsonic aircraft (due to higher takeoff speed). A burst tire flings tire parts at much higher speeds (hence more energy) than subsonic aircraft. What's worse about the incident last year was that it wasn't the first, and punctured fuel tanks as a result of burst tires had happened at least 10 times before. The operators were lucky that no serious incidences occurred as a result.

What I want to know is if any destructive testing on the modifications. The tanks are lined with Kevlar. Kevlar (stuff used for armour due to its strength) alone won't stop a leak (it is a woven fabric). It'll just (hopefully) stop tire parts and debris from penetrating the fuel tanks.
