Are they the same?

No, but the right size shouldn't be that hard to find

There are both 2015 circumference tires (ISO -642) and 2016mm tires. There's also another 28" size,
once used by CCM/Canada that would not fit a -642 rim at all but I don't recall the actual size of
those. So , maybe and maybe not.

Those tires are pretty hard to come by, though i think you can still get them from Coker Tire at
