Can I switch from a 27.5 x 2.1 tire to a 27.5 x 1.5 tire, and will a 27.5 inner tube (1.9-2.4) work with it? by TelephoneAgitated346 Bicycle bicycle culture Bicycling Bike Bike Culture Biking Biking culture Cycling cycling culture
thishasntbeeneasy on January 11, 2025 3:12 am Generally you can use a narrower tire, though that is quite a bit smaller. If you have wide rims, it may not fit very well. Similar with an oversized tube, it might fit, but why buy the wrong size? It looks like you are trying to avoid flats. I’d just stick to wider tires at lower pressure.
