Town and Country tandem tire size?

[Siestabikes]

what wheel/tire size does an early 60's T & C tandem have...597, 571, 584, 559?

S4 wheels take 26 x 1-1/2

I believe the T&C S4 rims took 584/650B tires. If I am correct, there are lots of quality options out there, as 650B has had quite a renaissance of late.

yep 26 X 1/2 also called 650B in the older days AND aka todays 27.5 in most bike shops.
The ISO is 584 . More common in/on European market bikes.
