But rather than tell him exactly what pressure to run, I came up with a quick guide to setting the pressure on your tires.
I’ve never used this guide myself, nor have I asked anyone to try it out. But I thought it might be an amusing way to think about your tire pressure.
Starting at 40psi, use the following tables to add or subtract total pressure.
STEP #1: RIDER WEIGHT
200 + 0
STEP #2: Style
Fluid and Smooth. Your wheels rarely leave the ground. You take turns with grace. -5psi
Aggressive and Hard. You huck everything in sight. You aren’t afraid to beat your bike. +5psi
STEP #3: Intention
Go Fast: +2psi
Have Fun: -2psi
Better Descending: -2psi
Corner Hard: +2psi
Step #4: Equipment
Tire seats snugly on the rim: -1psi
You’re carrying a tube and pump: -2psi
No tube and pump: +10psi
TALLY IT UP: using the above equation, my 160lb. self (rider + gear), (-6psi), that rides aggressive and smooth, and stays closer to the ground than the air (-1psi), wants to go fast, have fun, and descend better (-2psi), whose tires it snugly and is carrying a pump (-3psi), I should run at 30psi.
I typically run around 28psi. And I’d advise against running anything less than that.
What pressure did my equation give you?
