I believe this is actually a rare sighting, but why do some A320s such as the VT-ESD have double-bogie landing gear? Does Airbus have a specific reason for making such A320s?
Update: Found an image in the former Indian Airlines livery,

3$\begingroup$ It may be for operating out of airports where the per-wheel loading is lower. Having more wheels distributes the load more allowing the aircraft to operate out of lower quality runways. $\endgroup$– Ron BeyerJun 24, 2017 at 14:55

1$\begingroup$ Wikipedia says "Indian Airlines used its first 31 A320-200s with double-bogie main landing gear for airfields with poor runway condition which a single-bogie main gear could not manage" but does not cite a source. $\endgroup$– SanchisesJun 24, 2017 at 20:06

1$\begingroup$ I'm surprised that was an option on the A320. Does it require modifications to the wheel well and the aux gear doors for this? $\endgroup$– Romeo_4808NJun 25, 2017 at 2:55

$\begingroup$ @CarloFelicione I don't think the A320 can be retrofitted with double bogey landing gears. Airbus has definitely made a certain number of A320s that way, so the wheel well and aux doors must be larger $\endgroup$– Madhav SudarshanJun 25, 2017 at 7:06

Air India is the only carrier with that kind of landing gear in the A320 due to India's low pavement classification number back when those A320s were ordered. In other words, more tires distribute the load over a larger area.
