Need lots of tires in NYC
 

I know someone with a small expeditor/delivery business and has a small fleet of vans/livery trucks in NYC.
Anyone know where I can get a large amount of tires at a decent price?
Probably will need around 17-20 tires (single tires), most likely in different sizes for vans. If anyone knows or can suggest shops or places that have deals on new or slightly used tires in any of the 5 boroughs of NYC let me know!
Thanks :beer05:
