  1. The rims on my bike say, "26 x 1.5" but the tires I have are 26 x 1.95.

    Do I have the wrong size tires?

    I am shopping for new tires and I want to be sure I get the right size.

    By the way, any suggestions on MTB tires for road use?

    Thanks,

    Warren

    The second number relates to the width.

    You can use a certain range of tire widths safely on a particular rim width. Sheldon Brown gives
    a useful table on this near the end of his article on Tire Sizing. You need to go metric for this
    so have a go at the rest of the article and maybe get up to speed on tire sizes using the
    consistent ISO system. There is more here perhaps than you will want (or than I can recall after
    5 minutes anyway)

    It depends what you plan to do most. There is a choice from 25mm width Stelvios (high pressure
    fast tyres like a road bike) up to 60mm Big Apples just from the one brand Schwalbe. I've used
    their City Jets to give an old ATB a lot more go on the road without breaking the bank or shaking
    myself to death.

    26x1.5, I recall is a special size and is not readily available - at least in the US. I think this
    came on a few Schwinn models, but even Schwinn (yeah, I know - they are history anyway) did
    not really carry it too well. If you can find them, they are pricey. Consider swapping to a
    cheap set of "normal" 26" wheels and tires. It might even be cheaper than a pair of those
    special tires.

    Ignore Dan; he is misinformed. He is likely confused by the significant difference between 26 x 1.5
    and 26 x 1/2. The latter is the rare one.

    "Mountain bike" rims such as yours ( diameter 559mm) are labelled in decimals and can accept the
    full range of tires in most cases ( 26x1.125 through 26x2.4 are readily available).

    Popular commuting tires are smooth and about 1.5 to 1.75 wide. YMMV

    No, you're thinking of 26 x 1 1/2. This is the 584 mm size, more=20 commonly known by its French
    designation "650 B". That size was=20 formerly very common in France for utility bikes, tandems and
    loaded=20 tourers. This size was also occasionally used by Schwinn, and briefly=20 by Raleigh USA.

    You may think that 26 x 1 1/2 is the same as 26 x 1.5, but it isn't. In =

    bicycle tire sizing systems, fractions and decimals are NEVER=20 interchangeable. 26 x <decimal>
    tires are 559 mm, same size used on=20 virtually all mountain bikes and most cruisers.

    There are at least five different 26 x <fraction> sizes, none of which=20 is interchangeable with
    any decimal size. The link above gives all the=20 gory details.

    My bad. Ignore my previous comments.

    They are very expensive, but if you want very light weight, very narrow tires, look at the
    Continental Grand Prix. The Turbo Pro Classics and the inexpensive Fatboys - both from Specialized -
    are also worthy road tires.
