tire pressure calculator

Calculate recommended pressure based on vehicle load and tire specs.

Total Vehicle Weight (lbs)

Please enter a valid vehicle weight.

Front Weight Distribution (%)

Please enter a percentage between 0 and 100.

Tire Max Load Rating (lbs)

Please enter a valid max load rating.

Tire Max Pressure (PSI)

Please enter a valid max pressure.

Front Axle Pressure: 0 PSI

Rear Axle Pressure: 0 PSI

*These are calculated minimums to support the load. Always consult your vehicle door placard.

Why Accurate Tire Pressure Matters

Maintaining the correct tire pressure is crucial for vehicle safety, fuel efficiency, and tire longevity. Under-inflated tires can overheat, leading to blowouts, while over-inflated tires can reduce traction and cause uneven wear patterns.

How to Use This Calculator

This tool estimates the minimum tire pressure required to support your vehicle's specific weight configuration. To use it effectively, you need to know your vehicle's curb weight (plus cargo/passengers) and the specifications printed on your tire's sidewall.

Understanding Tire Sidewall Information

Every tire has a "Max Load" and "Max PSI" stamped on the sidewall. For example, you might see "Max Load 1709 lbs" and "Max Pressure 44 PSI". This calculator uses these figures to determine the proportional pressure needed for your actual vehicle weight.
