A 25mm inside width is also very wide; most hybrid type rims are 18mm or 19mm inside width; which following Sheldon's conservative chart would be 25mm tire min. As Dave says, Sheldon is rather conservative in this chart; many tires will work fine on 18mm interior width rims. Hello guys Thanks for the replies. So is it generally the case that if the outside width of the rim is 25mm, then a 25mm tyre n above should fit that rim?
If i was to go one tyre size lower than 25mm, is there some chance it could fit that same 25mm rim or would that be pushing it? Thanks again. You have to measure the inside width; no two models of rims have exactly the same side thickness. No generalizations are possible or reliable in this area. Unfortunately, I don't think there is a single, correct answer to this. It depends on rim shape, width, how tight the particular tires fit, how close they are to their listed size this actually varies a lot , etc.
As a general rule, I wouldn't go narrower than the outside width of the rim. I've seen people do it, but it's a little sketchy. If the tire is sloping inward at the point it exits the rim, I don't think there's any way your getting good engagement between the bead of the tire and the lip on the rim. Matching rim and tire width is probably fine, but I don't think anyone can say that absolutely. Again, I think the bigger question is what you're trying to achieve. If it's the narrow tire look, there's only so much you can do.
Thanks for the replies i think i will try a 28mm tyre which should fit the 25mm rim ok. Possibly Related Threads Last Post. Swapping 27" wheels for 26" wheels.

Schwalbe has produced this handy table which lists recommended tyre and rim width combinations. While you might be able to fit wider tyres to your rims, you might not necessarily have clearance in the frame and fork to accommodate the wider tyres. A bike manufacturer usually specifies a maximum width tyre for each model in its range, with a safe range of clearance between the tyre and frame, and you can normally find this information on its website.
The width of the rim can impact the width of the tyre. A 25mm tyre fitted to a wide rim can actually measure 27mm across, and it's a trick that some manufacturer have recently employed with their latest endurance bikes.
