Vintage look 26 x 1-3/8 tires?
 

The original tires on my Columbia are pretty cracked, and will need replacement soon. I'm looking for something that will closely match the look of the original "Silver Star Tyre" (made in Japan) - which has a block pattern tread (not my pic, but shows tread on these tires):

I know that back about 8-9 years ago there was a cheapo 26 x 1-3/8 tire that was about all you could find most places in that size, it had a similar if not identical tread pattern. But I can't recall the name. I thought maybe it was Kenda, but if it is they must have gotten new molds for their tires, or maybe nobody around here carries the old pattern if it is still made. Any ideas?

Search for Kenda and/or Sunlite K103. I think those may be the closest available match to your originals.

Great recommendation- Note that it is listed as a wheelchair tire, as is another that is a good choice which is the Vee Rubber vp18. Now finding them (in Canada) is a little more difficult.
