I picked up a '78 Raleigh Sports last weekend, it came with one new Kenda K103 tire mounted and one loose, marked 37-590, 26x1 3/8"
Here's the mounted one vs. an original on the right. They're not even as wide as most older 27x1 1/4" tires.
Both tires have 55 psi in them on Raleigh Westrick rims.
They look small, and likely won't provide much rim protection.
Time for some Michelins I guess.
