Hello All-

I have a 50's Rollfast and which is bone stock down to the tires. My question is this: The original tires read 26 x1.75 - 2.125. What is the appropriate tire for this bike? 1.75? What is the largest tires that I can run on these rims? The rims seem more narrow than my Dyno roadster which runs 2.125. Should I stick with 1.75? I am looking at brown schwalbe road cruisers. Will these fit? What do you guys recommend?

The rims should take 2.125 easily. The limiting factor will be clearance between the sidewall of the tire and the frame. Some Rollfast frames have plenty of room for balloons, some don't. Measure where the tire goes, and/or post photo.

Hhmm. That designation (with a range) may be found on tubes, but a tire is going to be labeled with a single size, either 26 X 1.75 or 26 X 2.125 or something' else. Have fun!

If it's a 50's Rollfast then 2.125 should fit fine. But a pic of the bike would help.

Is it better to choose 2.125? What are the advantages?
Well, they are wider so they look cooler :) Also in general smaller tires run higher pressure, so they would be faster since they transit more power but less comfortable. Wider tires tend to be softer and nicer for a cruiser bike. However the difference is not at all that significant.

Those cheapie Bell tires that they sell at Walmart are marked like that, with a tire size range rather than with a specific size. Good thing they have a generous return policy.

I didn't know that. Now I'm sorry that I know that because my head may explode. Do they not know the size of their tires? Is it a merchandising ploy? What is the world coming to?

I think it allows them to use the same part number/packaging no matter which manufacturer actually supplies the tires.

Sounds like a tube size rather than a tire size.
