Wanted to start a thread, hopefully a sticky for the actual calipered measurement of wide rims with tires. There isn't a place online that has a list of available widths that one can reference when trying to see if their frame will clear a tire. Lets try to include caliper pictures if we can although I don't have one for my first contribution.

Pacenti SL23 with 23mm GP4000- 24.2mm (~500mi of use).

If we get enough contributions I can maintain a list at the top of this thread.

If anyone has measurements for the new HED Belgian Plus that would be awesome!

Should thread title be changed to "Tire width on wide rims, real measurements"? Cause its the tire width we talking about, not the rim itself?

Disclaimer: not unlikely that I'm misunderstanding this...

Probably should agree on a standard inflation pressure as well.

Oh - and KWalker, those HED measurements for the Jet6 should be the same as the HED Belgium +. Same rim.

Strange thread. While width "can" be a factor, in my experience with road bikes and wider rims with clinchers, the more crucial clearance issue is the height of the tire. Usually it will hit the brake or fork crown or back of the seat tube before the sides of the stays become the limiting clearance factor. So, even with a bunch of width measurements of different combinations, you generally still need to put it in the frame in question with the brakes you're using to get a feel for clearance .

Measurement variables include:
1. Tire pressure.
2. Internal bead diameter of rim (width), not width at brake track.
3. Age of the tire. New tires will measure less than aged tires as they will stretch a little with time.
4. Measurements should be taken at different points of the tire and averaged out.
5. Operator error (i.e. squeezing calipers too hard against sidewall of tire can give skewed results).

Here are my measurements for various tires on my Bora One Clincher (17c internal bead width) and my Bora One Tubular, both inflated to 100 psi:

Bora Clincher/Tire Width:
Conti GP4000S II (23c) = 25.4mm
Conti GP4000S II (25c) = 26.7mm
Vredestein Senso (25c) = 25.4mm
Schwalbe One (25c) = 26.2mm

Bora Tubular/Tire Width:
Vittoria Corsa CXIII (25c) = 26.0mm

25 mm! Good catch..Conti definitely does balloon to a bigger size when on a fatty rim!
