27 x 1-1/4 v/s 27 x 1.25 - Embarrassed To Ask

SOLVED----
There must be something I have missed over all these years. Several sites that I have gone to order tires have two listings, one for 27 x 1-1/4 and another for 27 x 1.25... Huh?

Can you provide links to the sites so that we can see them?
I expect that someone made an error of some kind

Yes... Indeed... Site and sub sites have been corrected on Amazon and Ebay. There used to be a selection box labeled 27 x 1-1/4 and another labeled 27 x 1.25...

Just Amazon (or whoever created the posting on Amazon) being dumb and converting a fractional size to decimal, not realizing they mean different things in Bike Tire World.

I’ve seen sometimes that options listed in two colors have different “sizes” that amount to the same thing. Sometimes it’s just reversed. Not only on bicycle parts.

Yes, I had the same problem when I got my 1981 Schwinn Voyager. Found an old used 700c wheels and the problem is solved.

zandoval good choice on the panaracers. One of the few good tires still available in that size. Very nice.

To avoid confusion just go by iso sizing.

27 x1 1/4 is 32 - 630.

Maybe this is alreday assumed at this point, but the different choice of box to check surely indicates offerings from different vendors, while the product is the same (and which explains the wildly-different prices, lol).
For a time, the Sears brand would list all kinds of items at 3x normal prices, presumably just to cherry-pick the occasional clueless customer when/if their offering happened to be the only supplier on Amazon's or another site (or their own site). They presumably would know little about bicycle tires or wheel sizing, just that they were in the business of fulfilling orders.

A bigger concern might be that either 27x1-1/4 or 27x1.25 might mean a tire sized anywhere from literally 26mm to 32mm wide, depending who made it and when..
