    Low profile tires 25s

    Components,wrenching section I have been posting how I love 25 tires but I have rubbed off paint and roughed up carbonon on my 2007 Lemond Buenos Aires frame.
    Are there any low profile 25 tires that are not as tall!?
    Thanks in advance

    Not all 25mm tires are the same size. I think you'll have to compare your tire to other brands and models. You can find one that is smaller or use a 24mm tire or a large 23mm tire or you can use a 23mm tire on a wide rim.

    I believe a wider rim will effectively decrease the width of the same inflated tire, while increasing its width. could be wrong.

    Quality road tires are typically almost as tall as they are wide on standard rims. Beyond that the internal width of the rim tends to alter this relationship.

    Fixed it for you

    Edit: this may be a more accurate fix than my first attempt.

    I am not sure that is the case. Look at the HED image.

    Using the KISS methodology, consider getting better riding 23mm tires.

    I have 23 tubeless Fushion Hutchinson that ride very nice, and lower pressure use does not risk pinch flats.

    Depending on your weight, which I did not see mention by the OP... Or if wheels are tubeless capable.

    We had a protracted discussion on this in a revived thread earlier this year. A wider rim can lead to both tire width and height increases.

    It sounds like you want a tire that's supposed to be bigger but is smaller.
    you could get veloflex who's 25s are actually smaller than other 23s I've used. Or you could buy 23s and write 25 on them with a magic marker.

    I understand you like 25mm tires but that's because they are bigger. Getting smaller tires that are called 25s negates the reason you like them.

    I saw the other thread also. Just face the facts that your frame doesn't take 25 mm tires and sell it or learn to live with it.

    Try Veloflex Corsas. Not only are they narrower than other 25s I've tried. But their sidewall is not as tall too giving you a low profile look.

    Saw the pic but frankly never studied it...till this evening and then I went to do my own measurements.
    Measured a 28mm Conti 4kSii on a 14mm rim and on a 17mm rim. The tire grew by 3mm in width and a couple of tenths in height as well. The crossectional outline of the tire changed as well. Did not dismount the tires to see how different the bead hooks may be, if they are, so I don't know if this may be a variable affecting the outcome.
    The increase in height appears to be counterintuitive at first thought but it is there although in minimal proportions to the increase in width.

    My experience going from a standard width rim to a 25mm wide rim is that both the width and height of the tire grows. Granted the height only grows slightly.

    Almost every company makes a low profile 25. Just look for the ones labeled 23.

    I loved 25's too. When I switched to my HED + rims I found that a 23mm tire measures more than 25mm when installed.

    The OP could try some 25's that run small, like a Conti 4 seasons, but that would be no different than running a 23 that runs large like a Michelin. The point to the OP is don't get hung up on the number "25". You need a smaller tire on your bike. Find the largest physical size, not labelled size, that will fit. Do a search for installed tire widths to narrow down your search, I know people have recorded such things.

    I am not nit picking but I think your statement is factually wrong.

    1. True: a 25 mm labelled Michelin whether Endurance or Pro4 Race runs large at the order of 70-72mm (measured flat).

    2. Wrong: a 23 mm labelled Michelin whether Endurance or Pro4Race runs large. It runs very, very small approx 60mm.

    3. True: a 23 mm labelled old (year <2008) Michelin Krylion runs large: 64 mm flat.


    4. Wrong (agree: no first hand experience from my side): a 25 mm labelled Conti 4 Season runs small compared to a 23 mm Michelin. A 25 mm Conti 4 Season runs large and true to size approx 68 mm flat.

    5. True: a 25 mm labelled Conti Gatorskin runs smallish by comparison: 64 mm flat.

    OP: Please answer the following: what tyre are you using.

    Still a lot depends on the shape and thickness of the rubber and a single measure does not tell the whole story, e.g. people always neglect the height of the tyre o the rim when talking about tyre size.

    However, would you fancy taking a measurement of the flat tyre. I personally think everything > 68 mm for a 25 mm tyre is large.

    As I already have mentioned: 23 mm vs 25 mm Michelin. Sounds small - 2 mm - right? Not so, if you take into account a whopping 12 mm (60 mm vs 70-72 mm when measured stretched out flat) or nearly half an inch in the extreme case.

    maybe consider Specialized Roubaix 23/25mm tires. It's like a 23mm tread with a 25mm casing.
    2010 Specialized Secteur Elite with the RBR not-approved Mavic Ksyrium Elite wheelset
    2009 Specialized Rockhopper Comp 29er upgraded to SRAM X9 with 1x10 and Stan's Arch EX rims and tubeless.
    2013 Cannondale CAADX-6 Tiagra with 9-speed SLX RD to run 11-32T cassette and Stan's Alpha 400 rims and tubeless
    and
    Some Burton snowboard setups, one with stiff ol' Camber and one with Rocker-Camber-Rocker

    I hope they have improved on quality. Had this tyre some years ago: same piece of crap as Schwalbe tyres and very unsafe to ride and will disintegrate. The idiots from Specialized refused to honor the warranty (front and rear disintegrated) and claimed I am the first ever to have any problems with Specialized tyres. Such a bunch of wonkers: the internet at that time (4-5 years ago) was full of tyre blowouts threads of that particular tryre.

    Since then I have not been taking any chances with buying anything Specialized.

    The 23/25 mm Specialized tat was a very big tyre - also in height - if I recall correctly. I do not think this tyre will solve the OPs problem to be honest.

    I haven't had issues with Specialized MTB tires though.

    The narrowest 25c tire I have found so far is the Vredestein Fortezza Senso All Weather. It measures the same as my Conti GP4000SII 23c.
