I have a tube (fits 27.5", 28" and 29"), and a 27,5" tire with the dimensions 57-584 (27.5/2.25, 650B). But the package of the tube only shows suitability for the dimensions (27.5"):

  1. 50-584 27.5 x 2.00 650B
  2. 60-584 27.5 x 2.35 650B
  3. 62-584 27.5 x 2.40 650B

Can I use the tube for my tire? What would be possible consequences?

The tube and tire are from Schwalbe SV-19

    Tubes are elastic and fit different tyre sizes and even rim sizes within a reasonable range. Also 27.5 and 650B are the same dimension but in a different system. Look here for comparison tables: sheldonbrown.com/tire-sizing.html#iso – Carel Nov 6 '18 at 20:34

  • I've never seen a inner tube that fits several wheel rim diameters. What makes you think this tube can fit 27.5", 28" and 29" wheels (ETRTO 559, 584, 622)? – Argenti Apparatus Nov 6 '18 at 21:28
  • @ArgentiApparatus That's the tube. – user51497 Nov 6 '18 at 21:50
  • Link does not work for me (I'm in the US), but you are right. I looked up the SV-19, Schwalbe's website says it fits 584mm and 622mm rims. (29" and 28" both refer to 622 rims, 29" is an MTB term, 28" a road term) – Argenti Apparatus Nov 6 '18 at 22:03

'584', '27.5' and '650B' are all the same thing, specified in different wheel size systems.

These size wheels originated in the older French wheel size system and are called 650B (650mm being the diameter of wheel and tire). ETRTO (European Tire and Rim Technical Organization) specifies wheel rim diameters in millimeters (584mm in this case). Mountain bikers call these 27.5" (the approximate diameter of the wheel and a fat MTB tire).

The tire width specifications of your tire and the tube are given in both millimeters and inches. Tube min tire width is 50mm / 2.00", max is 62mm / 2.40"

Your tire width is 57mm / 2.25" so the tube will work with it just fine.
