Tire outer diameter chart?


Recommended Posts

Looking for a chart, or listing of common ds tire outer diameters.

I've found Kenda lists the od's on their site, and helmetheadcycle has a lot of od's listed too... but I'm not finding listing's specifically for Metzler and Conti tires

It would be nice to know in case I want to "up gear" a little bit with OD when I pick up new tires... or to at least have a clue how they compare to stock.

You can figure it out from the tire and rim size.

100/110-18; the section width is 100mm and the sidewall is 110% of that, so 110mm. Multiply that by two and add the rim height of 457.2mm/18" and you get a diameter of 677.2mm/26.67". Multiply that by Pi (3.14159) and you get a circumference of 2128mm/83.76".

Thank you for that.

I've found a caveat on a site that talked about the math... apparently not everyone measures section width the same (or i should say, the tread width can be bigger/smaller than section), so you may get a slightly different diameter between two tires with identical numbers.
