Tire Pressure Calculator

Tire Pressure Calculator — Calculate Optimal Tire Pressure for Your Vehicle

Calculate the optimal tire pressure for your vehicle with our comprehensive calculator. Determine correct PSI levels based on vehicle type, load, driving conditions, and temperature.

Step 1: Vehicle Specifications

Vehicle Type

Tire Size (e.g., 225/65R17)

Current Tire Pressure (PSI)

32 PSI

Understanding Tire Pressure

Proper tire pressure improves fuel efficiency, extends tire life, and enhances safety. Check pressure when tires are cold for accurate readings.

Step 2: Driving Conditions

Vehicle Load Condition

Primary Driving Type

Ambient Temperature (°F)

70°F

About Temperature Effects

Tire pressure changes with temperature: For every 10°F change, pressure changes by about 1 PSI. Check and adjust pressure seasonally.

Tire Pressure Formula

Optimal Pressure = Base PSI + Load Adjustment + Temperature Adjustment

Base PSI varies by vehicle type. Load adjustment adds 0-5 PSI for heavy loads. Temperature adjustment adds/subtracts 1 PSI per 10°F from 70°F baseline.
