Gazelle Ultimate C380 tyres
The Gazelle Ultimate C380 runs 47-622 and 55-622 in ETRTO sizing, the width in millimetres followed by the rim bead seat diameter. The Cannondale Tesoro Neo X takes the same size.

Your own placard is the authority. You will find it on the printed on the tyre 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 tyre.
What changes on this bike
The current C380 runs Schwalbe's Green Marathon in 55-622, a tyre made with 80 per cent recycled and renewable material that Schwalbe still rates E-50 with ECE-R75 certification.
Early US C380+ HMB bikes from 2021 used a narrower 47-622 Energizer Plus, so an owner of an older bike should check the sidewall before assuming the 55 mm size.
The 2021 US C380+ used Bosch's Performance Line Speed motor (28 mph); the Green Marathon's ECE-R75 certification covers that use, which a 25 km/h-only tyre would not.
No tyres listed against this fitment yet. Product specifications are published from each manufacturer's own data and that work is not finished for 55-622. Match or exceed every figure in the table above and you cannot go far wrong.

Common questions
- What size tyres does the Gazelle Ultimate C380 take?
- It runs 47-622 and 55-622. The exact fitment for your bike is on Printed on the tyre sidewall, next to the pressure range.
- Can I fit a cheaper tyre to a Gazelle Ultimate C380?
- Only at 55-622 or better. That is the figure to hold: a tyre below the load index, the speed rating or the construction class is not a cheaper one, it is the wrong one.
