As well being an aviation classic the Boeing 747 is a design classic. Its shape is more recognisable than any other aircraft and its grace, poise and elegance belie its proportions.
Notwithstanding some super large aircraft such as the Antonov 124 and Antonov 225 the Boeing 747 is amongst the select group of airliners fitted with a staggering number of tires.
Sixteen H49x19.0-22 (DR26020T) aircraft tires are fitted to main gear bogies beneath the wings and the fuselage of the Boeing 747-400. It was the only way enough tires could be deployed to support the immense loads of this incredible airplane.
Unusually for most modern aircraft, the Boeing 747-400 nose gear tires are the same size (H49x19.0-22) as the tires fitted to its main landing gear.
In total eighteen of these enormous tires are required to safely operate the Boeing 747-400. Each one of these tires can be retreaded up to seven times which reduces the overall cost of ownership of the tires for Boeing 747-400.
