Tyres and tubes guide
Choose fat eBike tyres and tubes by the real fitment: tyre size, wheel diameter, clearance, tread, tube size and the way you ride.
Quick chooser
Fat eBike tyres are not just a style choice. The right option depends on the printed sidewall size, the bike's clearance, the tread pattern and whether you need a spare tube for regular riding.

Use the size printed on the current tyre as the starting point, then check frame and fork clearance.
Lower pressure can feel more comfortable on fat tyres, but stay within the tyre rating and avoid pinch-flat risk.
FAQ
Yes. Both are 20-inch fat-tyre sizes, so they fit the same wheel diameter. The extra width means frame and fork clearance should still be checked.
Match the tube to the wheel diameter, tyre width range and valve type printed on your current setup.
