Hi Mathew,
The S4 rim is the same as 650B which is a popular size for French tandems and touring bikes, and has recently been used for mountain bikes.The rims are a little bit taller than S2s. The tires are not interchangeable, so you need to buy 650B tires for S4 rims.

the original tires for the S4 rims were 26x1-1/2 " the 650B tires work,but never seem to fit just right.the Schwinn Hurricane 26x1-1/2 tire are still out there.I recently picked up a set for my 53 welterweight.
