Is this the pressure printed on the tire?
No. Sidewall maximum is a limit, not a ride setting. Start here, then adjust after a short ride.
ATV Calculator
ATV Tire Pressure Calculator
Find a cold starting PSI for ATV tires based on load, tire width, and whether you are riding hardpack, sand, mud, rocks, or snow.

How it works
Each terrain has a base pressure. The calculator then nudges that number up or down for heavier loads and wider tires.
Starting PSI = terrain base + load adjustment + width adjustment, with a 4 PSI floor. Always stay below the tire's maximum sidewall rating.
These results are estimates for planning only. They are not OEM specifications, safety certifications, or professional mechanical, legal, or financial advice.
Tire Pressure Calculator FAQs
Why is sand pressure so low?
Lower pressure grows the contact patch in loose sand. Too low on rocks can pinch a tube or damage a bead.
Front and rear the same?
Many riders run fronts a little lower for steering. This page gives one starting number for the whole machine.
