Whether the WTB Nano fits your bike is decided by one number: the bead seat diameter, the second half of an ETRTO size. This tire is made for 622 mm rims (700C / 28-inch / 29-inch). If your rim matches, the only remaining question is width, and that is a matter of frame and fork clearance rather than of fit.

All 8 listings
8 listings across 2 sizes. Where a size appears more than once, those are genuinely different products — a different casing, colour or claimed weight. The “printed as” column is WTB's own marking for that size, which is what you will find on the sidewall and in most shop listings.

|---|---|---|---|
| 40-622 | 470 g | 530 g | 10th lightest of 65 |
| 52-622 | 685 g | 685 g | 8th lightest of 15 |
