Schwalbe tire labeling (Supreme)

[fredbyte]

Just bought the Schwalbe Supreme 700x40C (42x622) folding tire because I wanted a portable backup for touring. I had the choice of going with the 700x35C or the 700x40C. I was worried because my Schwalbe Marathon Plus 700x38C (40x622) just barely fit under my fenders. [The Marathon Plus label is correct. My 700x38C (40x622) actually measured 40.0 mm in width.] But, I saw on the Rivendell Bike website where they claimed that the Supreme actually measured 37.5 mm in width. So I took a chance and went with the 700x40C Supreme (from another merchant). Rivendell was right. I put the Supreme on my Velocity Dyad rim (24.0 mm external dimension) and the tire measured 37.8 mm in width at 80 psi. So, you can't always go by Schwalbe's dimensions. I wanted as much "fat" in my tire as possible for stability reasons, especially while riding on hardpacked dirt/gravel.

Hope this helps future purchasers.

Thank you for the heads up, and yes even other tire application go at best a guess!

Hello, guys.

I'm thinking about getting a pair of these Schwalbe Marathon Plus for the 700x28 size. I currently have 700x35 Specialized Nimbus, after I got tired of the hardness of the 700x23.

I am wondering if the speed gain from 700x35 to 700x28 is any good, when thinking about the comfort loss.

What do you think?

Thanks a lot.

Play this game long enough and you will find that tire width designations vary not only among mfrs but also within models of a single manufacturer. It may be left up to the engineer that designed it,,, I don't know.

Port. You started with 23 and went to 35, and now thinking of trying 28?
Sounds like you're on the right track.
We can't answer that Q, Port. Only you can prevent forest fires.

Your riding style and terrain / road conditions will gravitate you to a good tire (and size) if you pay attention to what you Do and Don't like about the current rubber. Wear them out.

@ Portellini: see answer in other thread where you posted the exact same question.

nah; Marketing is in charge of all the labeling, occasionally they will listen to Engineering's input.
