How wide tires can one put on a 622x15C rim?
Currently those on are the accursed 23-622 or 700x23C. TIA -- underground experts united http://user.it.uu.se/~embe8573 |

So, supposing your rims are actually 15mm on the inside, you could theoretically fit 37mm tyres. If your rim manufacturer misleadingly tells you the outside measure of the rim, you should measure the inside width yourself and proceed from there. Here's a worked calculation for a true 29er: 1. 1in + 736.6mm (we use a period, a full stop, for the decimal separator) 2. Rim diameter 622mm 3. (737 - 622)mm/2 = 57.5mm tyre width 4. Most desirable tyre for application is Schwalbe Big Apple 5. Schwalbe offers the Big Apple in 60mm, slightly larger than 29er requires, and the bike has clearances for such a big tyre plus the associated mudguards 6. Minimum inside rim width is 60mm/2.5 = 24mm 7. 24mm and 25mm inside measurement 622mm diameter rims are available 8. It may be better to use a rim width factor of 2, so 60mm/2 s = 30mm 9. 30mm inside width rims are available, built for monocycles Andre Jute So many choices. I blame Adam Smith. |

According to Schwalb, you can go from a 23 to a 32 tire in a 15C rim.

Interesting. No, 32 is perfect, I think! -- underground experts united http://user.it.uu.se/~embe8573 |

Cheers I forget the term for that but it can also occur if you use tubeless tires at too low a pressure. |

TIA -- underground experts united http://user.it.uu.se/~embe8573 You can put any size you want on there. The only problem that could occur is if the sidewalls are very thick in which case there's no room for the tube to expand inside the rim hence holding the tire in place. Not likely for good-quality tires. |

Not likely for good-quality tires. See https://www.sheldonbrown.com/tire-sizing.html nearly the bottom of the page. Says 23, 25, 28, 32mm cheers, John B. |
