I read somewhere that switching to alloys from factory steel rims will decrease pay load capacity.

Is that true?

I have a Nissan NV200 and payload is 1500 lbs. Stock wheels are these tiny and expensive 185/60/15 cargo rated tires on steel 15" rims. I picked up a set of 16" aftermarket alloy rims and am upping to a 215/60/16 tire(It will fit perfectly).

My question is, the new tire load rating matches the OE tires, but will my pay load be decreased? since steel rims are stronger than alloys?

If the new tires have a sufficient load rating you can carry the same payload. However, regardless of whether of not they "fit" the tire are significantly bigger and will adversely effect performance, you are effectively changing the gear ratio of the drive line. Speedometer readings will also be off.
