Never knew that Airbus offered their A320 with 4 wheel main gears. Searching through the photo data base it seems that only Indian Airlines/Air India flies them. Any special reason or performance advantages ??.....possible higher GTOW?

The reason was so that they could use "rough" fields where the normal wheel loading was too high. There was a weight penalty since the bogies are heavier and the gear doors larger.
As you noticed, only one airline ordered the mod, which IIRC was done by a third party. AFAIK they are all in the process of being converted to the standard wheel arrangement, if they haven't been already.

Quoting Brenintw (Reply 2): This modification was only used in India (mostly for unpaved runways).
I am fairly certain they never operated on unpaved runways, but on paved runways with a low bearing strength that couldn't take the weight of the aircraft unless it was spread over 4 wheels per side rather than two.
