How do you know what size tyres will fit your bike?

Don't trust a fabric measuring tape as used in fitting clothing.
This kind is usually inaccurate, because the fabric stretches.

Our example rim is a hook-edge rim without clearly-defined bead inchh, so we'll measure from the well but not the bottom of the recessed spoke holes to the outside of the rim and then subtract twice the typical flange height. Our highly-sophisticated tool for this task is a bicycle spoke.
We are also using a small ruler as a bridge across the rim flanges. Holding the spoke with a thumbnail against the ruler gives us a good enough measurement for our purposes.
This article has featured common, inexpensive and improvised urban bicycle. More sophisticated tools such as a caliper with a depth gauge can make the work go faster. About mathematics Measuring rims involves some elementary-school or pocket-calculator math.
Sheldon quoted Robert Heinlein at the end of the article:. More about that quote. OK, so Heinlein actually, a character in one of his books said that, and Sheldon quoted that, but anyone who cannot accept that other people have gims abilities and target hours spokane opportunities shows an unfortunate lack of compassion!
I'm hoping that this article provides an easy guide to some practical math, and helps to dispel math anxiety. Also, a longer discussion of the Einstein quote is online, in case you're interested Accessories Bicycles Parts Specials Tools.

And a recently fitted tire still widens over time. This can make a difference of 1 to 2 mm. The question whether tires will fit into a particular frame is often asked in relation to our ultra-wide tires.
Please bear in mind that with the large number of different bicycle models it is impossible to check the compatibility of all frames and tires. The following list shows the exact diameters and widths of our tides wide tires.
