About this calculator
Calculate the ideal tire pressure for your bikepacking or touring setup based on total loaded weight, tire width, wheel size, and terrain.
Frequently Asked Questions
Why does rear tire pressure differ from front?
Rear tires typically carry more weight due to rider position and rear panniers, so they need slightly higher pressure to avoid pinch flats and excessive squirm.
Should I run lower pressure off-road?
Yes, lower pressure improves traction and comfort on rough terrain, but too low risks rim strikes and pinch flats, especially with a loaded bike.
Does tire width really change the ideal pressure that much?
Yes, wider tires support the same load at lower pressure because they have more air volume and a larger contact patch.
