650b tire help!
I was given an American Eagle. Beautiful coaster brake bike made in Japan in the 60s. The old tires said 26 x 1x3/8. They're not even close to a standard 559 tire. I have a set of 650b Panaracers. After breaking 2 tire levers, I got one on. It was the worst tire wrestling match ever. Of course the tube is pinched. Are my Panaracers undersize? Or is there a mysterious Japanese tire size?

Why are there 5 different sizes of 26 1-3/8 tires? I've run into Schwinn, English, standard 559, 650B, and now 650A. All of these were marked 26 1-3/8.
If you can't take a joke...............

British and french bicycle tire standards are well known to be the summit of human idiocy.
They both state the idealized outer diameter of the tire, not the rim. So as the tire fattens, the rim shrinks - even though it's still a 26" wheel.
ERTRO rules supreme.

For an American Eagle you want tires that are 590 x 38 ISO. If you check around online line there is a large selection of tire in this size. There have been several lengthy threads on this subject here recently.

I miss Sheldon Brown. Thanks for the link.
The only markings the rim had on it was 26x 1- 3/8. This promises to be a nice bike. Doesn't have much signs of use. Judging by the weeds growing in the front rim, it spent time under the eaves in someone's back yard.
