1. What is Correct Tire Pressure?

Correct tire pressure is essential for vehicle safety, fuel efficiency, and tire longevity. It combines the manufacturer's recommended placard pressure with adjustments for specific load conditions.

2. How Does the Calculator Work?

The calculator uses the tire pressure formula:

Where:

• \( Placard \) — Manufacturer's recommended pressure (psi)
• \( Load Adjustment \) — Additional pressure for heavy loads (psi)
• \( Recommended PSI \) — Final calculated tire pressure (psi)

Explanation: The formula ensures optimal tire performance by accounting for both standard operating conditions and additional load requirements.

3. Importance of Correct Tire Pressure

Details: Proper tire pressure improves fuel economy by up to 3%, extends tire life, enhances vehicle handling, and reduces the risk of blowouts and accidents.

4. Using the Calculator

Tips: Enter the placard pressure found on your vehicle's door jamb or owner's manual, then add any necessary load adjustment for heavy cargo or towing.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find the placard pressure?
A: Typically located on the driver's side door jamb, glove compartment door, or fuel filler flap. Check your vehicle's owner's manual for exact location.

Q2: When should I add load adjustment?
A: When carrying heavy loads, towing trailers, or during long trips with full passenger capacity. Usually 2-4 psi above placard pressure.

Q3: How often should I check tire pressure?
A: At least once a month and before long trips. Check when tires are cold for most accurate readings.

Q4: What happens if tire pressure is too low?
A: Reduced fuel efficiency, uneven tire wear, poor handling, and increased risk of tire failure or blowout.

Q5: What happens if tire pressure is too high?
A: Reduced traction, harsher ride, uneven tire wear (center wear), and increased vulnerability to road hazards.
