Frequently Asked Questions
Wider rims will cause a tire to also have a wider width, with more air volume within the tire and a flatter tire tread profile than designed for. As a general rule of thumb, a 2mm increase or decrease of inner rim width will result in a tire section width increase or decrease of 1mm. For example, our Nano 40 tire has a tire section width of 40mm on a 21mm inner rim width, however it will have a tire section width of 41mm on a 23mm inner rim width.
CZR i23 rims feature a hooked bead because doing so provides a more dependable connection between the tire and rim when running a tire at the higher air pressures that are common with adventure road and gravel riding. CZR i30 rims feature a hookless bead because the smooth bead surface allows for more material to be used in an area when strength is incredibly important. Both CZR i23 and CZR i30 rims are compatible with any tires that comply with ETRTO standards.
All of our alloy rims work great with a 34mm valve stem. If you are using a deeper dish rim, like our CZR i23 rim, then we recommend the 46mm long valve stem. CZR i30 rims accept either length of valve.
Asymmetrical rims feature a "short" and "long" side. It is helpful to always mount both sides of the tire onto the rim on the "short side" of the rim. The short side of the rim provides the shortest distance between the rim leg/bead and the valley of the rim. Once the first tire bead is completely on the rim, it can be pulled over the rubber portion of the valve and positioned at the deepest part of the rim valley. The other side of the tire can then be installed onto the rim with the least amount of resistance.
