What tire size are these?

The beach cruiser style frames are not my style.

Are they 26"'s? 650b? Can I replace the rims with anything else? I'd rather not implement a coaster brake hub.


Open to other recommendations ye' may have. Something modern would work too but I can't find any old style like that.

Nothing wrong with coaster brake if it is the old Bendix, or New Departure. And being a single speed it will more likely have 26" wheels, around 2.00 tires. Should be able to put 2.25's one them rims, nice old bike ..........Curt
