Tire Pressure Calculator

Step-by-Step Guide to Using the Tire Pressure Calculator

Introduction

This guide will walk you through the process of using the Tire Pressure Calculator. With this tool, you can calculate the recommended tire pressure for the front and rear tires of your vehicle based on specific conditions such as load weight, temperature, and altitude. Follow the steps below to ensure accurate calculations.

Step 1: Provide Vehicle Details

• Select Vehicle Type: Choose the type of your vehicle from the options provided:
  • Passenger Car
  • SUV/Crossover
  • Light Truck

Step 2: Enter Load Weight

• Vehicle Load Weight (kg): Enter the total load weight of the vehicle in kilograms. This should be a number between 0 and 4000 kg. Ensure that the given weight is accurate to prevent any miscalculation.

Step 3: Input Manufacturer’s Recommended Pressure

• Manufacturer’s Recommended Pressure (PSI): Type in the recommended tire pressure as stated by the manufacturer (in PSI). The value should range between 20 and 80 PSI. It’s crucial to refer to your vehicle’s manual for this information.

Step 4: Provide Environmental Conditions

• Current Temperature (°C): Enter the current ambient temperature in degrees Celsius. Acceptable values range from -40°C to 60°C.
• Altitude (meters): Enter the current altitude in meters. Valid entries should be between 0 and 5000 meters.

Step 5: Review the Results

• Recommended Front Tire Pressure: The calculator will display the adjusted tire pressure for the front tires based on the inputs provided. This is calculated using the formula:
  baselinePressure * (1 + (loadWeight * 0.00015)) * (1 + (temperature * 0.004)) * (1 - (altitude * 0.00002)).
• Recommended Rear Tire Pressure: The recommended pressure for the rear tires will also be shown, calculated as follows:
  baselinePressure * (1 + (loadWeight * 0.0002)) * (1 + (temperature * 0.004)) * (1 - (altitude * 0.00002)).
• Front-Rear Pressure Differential: The difference between the front and rear tire pressures is calculated and displayed using the formula:
  abs(frontTirePressure - rearTirePressure).

Follow these steps carefully to ensure that you obtain precise and safe recommendations for your tire pressure needs under the given circumstances.
