Different models are equipped with different sized tires: 

Fatboy Comp Carbon: 26 x 4"

Fatboy Base: 26 x 4.6"

Fatboy SE: 26 x 4.6"

Generally speaking, lower tire pressures provide better control on wet or loose terrain, as well as a smoother ride. Higher tire pressures provide better puncture protection. Check your tires frequently to ensure your tire pressure is in the appropriate range.

The right tire pressure for your ride is personal and depends on your riding style, the terrain you'll be riding and the conditions of that terrain on the day you're riding. What you see below is a recommendation of a starting point pressure, a "ballpark" if you will, based on rider + gear weight and tire width. You'll also see a decal on your wheels indicating maximum inflation pressure. Never exceed the maximum inflation pressure of your tires or rims. Enjoy your ride!


Mountain Tire Pressure Data Table

*Crossed out cells: tire size not recommended, as the rider's weight may require a tire pressure that is too high for the tire or rim.

Tubeless conversion

Many riders choose to convert to tubeless tires to prevent pinch flats. Tubeless tires allow riders to use lower inflation pressure without the risk of damaging a tube from impacts. While the Fatboy models listed above have tubeless-compatible rims, you will also need to install tubeless-ready tires, valve stems, and rim tape. For more information, see our Tubeless Conversion page.
