597 is a more Schwinn-specific size in that neighborhood, although it was also used by some other brands.
590's... old 3 speeds mostly...
i have a "schwinn" here with "schwinn Cruiser classic" tires on it... no ISO numbers to be found... the rim measures 22.675 dia.... the bike is a mix of schwinn-like steel, and shimano bits.
the raleigh limited 3 sp. has 590's on it, the rim dia. is 24 inches even. No ISO numbers showing on the tires or rims...
and the old three speed someone gave me has "Million" brand tires(no ISO# showing), a sturmey archer 3 sp.hub, and rim dia. is 23.75... the previous owner said the bike is a Murray...
both 3 speeds have tires labeled as 26 x 1 3/8"... the "schwinn" has 26 x 2.125" on the tires... i'll assume they are beaded tires, not schwinn type... since the rims are standard MTB diameter... tread is rectangle checkerboard pattern, much like schwinns of old.... sigh.
and if i dig thru the boneyard, i might find a couple other "26 inch" rim sizes out there.....
no wonder the OP ended up with the wrong tires.....
