i was also searching for Altis OEM alloys, went to sultan ka khoo but couldn't find genuine rims. Most of the sellers were claiming their rims to be original but they were actually good copies. However, found one shop forgot its name (maybe it was nexen tyre shop) that guy was having some good branded stuff. visit his shop, you may find it a right place. Location is murree road, coming from saddar towards faizabad bridge its under the flyover which is infront of raabi centre. Goodluck
