I won't call you out on not owning your own set of calipers for your home workshop because you are stepping up and taking care of this research (unlike Lazy Don).

donkpow Posted October 18, 2017 Share #52 Posted October 18, 2017 Okay, look. Manufacturers don't just stamp their tires with some arbitrary number. There is a procedure to determine the "width" of a tire in order to comply with the ISO standard. This is not to say that your 'measured width' won't be different from wheel to wheel. On a given rim, a tire designated as 23-622 will be narrower than a 25-622 tire when mounted, inflated, and measured. Link to comment Share on other sites More sharing options...

Any ideas where you come up with that nonsense? While I agree that Contis 23s will be narrower than their 25s which are narrower than their 28s, I don't agree that their 25 will be narrower than other brands 26s nor wider than other brands 24s.

Tom I have never measured the differences but I have been under the understanding that 3 tires of the same nominal size from 3 different vendors mounted on the same rims, inflated to the same pressure could all measure different widths. Some times by as much as 2mm. Link to comment Share on other sites More sharing options...

Or even different total circumference? Where do you stand on this topic? Tom Link to comment Share on other sites More sharing options...

Tom Assuming the rim dimensions are the same as established by the ISO standard for determining the width of a tire, I would expect all three tires would measuring very close to the same. Circumference or overall height isn't accounted for in the standard, ASFAIK. I don't stand anywhere near this stuff. Link to comment Share on other sites More sharing options...

Any bigger would likely be an issue. With the new disc brake set-ups, it is less of an issue for many bikes. I believe these are the Continental Grand Prix 4Season Clincher Road Tyre Black 700c x 28mm. Tom 1 Link to comment Share on other sites More sharing options...

Not all 2.5's are created equal in regards to clearance. But we have knobs. Link to comment Share on other sites More sharing options...
