Hello,
A neighbour is tossing this old CCM, and I thought if use it for a cheap bike challenge build.
Tire size is 26 × 1 3/8 – 650 × 35A.
Will a standard 26″ (MTB) tire fit this wheel or am I out of luck?
I did some digging and also saw it referenced as 650A.
What are my options here?
Thanks in advance.

Edit: there’s a list of 650a tires on Sheldon Brown. Most aree sold out. Would love to know if I could put other tires on this rim.
The current ones have flat spots from being in storage for years.
No an MTB 26″ has a bead seat diameter of 559mm, this tyre has a bead seat of 590mm (650A is an almost defunct tyre size).
26×1 3/8 is the tire size. 650A is the same. The 590 is the important number. Schwalbe marathon plus comes in that size.
Some old Raleigh or Schwinn bikes used this size. It’s still around but only in street/townie type tires. Ask at a couple lbs for an old 3 speed type tire, with 590 iso. Most employees should know what that means, or know enough to look it up. A shop that does more city/commuting/vintage stuff would be my starting point.
Keep reading on Sheldon Brown about tire sizing. It’s interesting and moderately insane.
Schwalbe still make tyres in this size
