Canyon Spectral:ON tires
The Canyon Spectral:ON runs 63-622 in ETRTO sizing, the width in millimetres followed by the rim bead seat diameter. It is staggered: a 63 section at the front and a 63 at the back, so the two can never be swapped across axles and the rear goes first.
Every fitment
| Generation | Trim | Wheel | Tire size | Inch size |
|---|---|---|---|---|
| Current | Spectral:ON CF 7 / CF 8 (Maxxis Assegai front, Minion DHR II rear) | 29in front / 27.5in rear | 63-622 front, 63-584 rear | 29x2.50 |
Your own placard is the authority. You will find it on the printed on the tire sidewall, next to the pressure range. Where it disagrees with this page, it wins. Match or exceed the size, load index, speed rating and construction class it gives, and use its pressure figure rather than anything printed on the tire.
What changes on this bike
The Spectral:ON is a mullet: a 29in Maxxis Assegai 2.5 at the front and a 27.5in Minion DHR II 2.5 at the back, so front and rear differ in both pattern and bead diameter.
Older Spectral:ON CF 8 bikes, now sold through Canyon's outlet, ran a wider 27.5x2.60 DHR II rear (66-584), so check which generation you have before ordering a rear.
Maxxis lists the 29x2.50 Assegai at 63-622 and the 27.5x2.50 DHR II at 63-584 in their Wide Trail form, matched to the 30 mm DT Swiss rims on the CF 8.

Common questions
- What size tires does the Canyon Spectral:ON take?
- It runs 63-622. The exact fitment for your bike is on Printed on the tire sidewall, next to the pressure range.
- Can I fit a cheaper tire to a Canyon Spectral:ON?
- Only at 63-622 or better. That is the figure to hold: a tire below the load index, the speed rating or the construction class is not a cheaper one, it is the wrong one.
