The Truth About Tire Pressure: What Every Driver Needs to Know

Have you ever checked your tire pressure and noticed two different PSI numbers—one on the tire itself and another inside your vehicle’s door jamb? It’s a common question: Which one should you trust?

The Short Answer:

Always follow your vehicle’s recommended tire pressure—not the number on the tire.

Understanding Tire Pressure Ratings

🔹 The Number on the Tire: Maximum PSI

The PSI listed on your tire’s sidewall is not the ideal pressure for daily driving. It represents the maximum pressure the tire can safely handle before risking damage. Inflating your tires to this number can lead to reduced traction, uneven wear, and even an increased risk of a dangerous blowout.

🔹 The Number on Your Door Jamb: Recommended PSI

Your car’s manufacturer has spent years testing and fine-tuning the ideal pressure to optimize safety, performance, and fuel efficiency. This recommended PSI ensures:
✅ Proper weight distribution
✅ Maximum grip and stability
✅ A comfortable ride
✅ Even tire wear for long-lasting performance

Why Overinflation is Risky

🚨 Reduced Traction – Overinflated tires have a smaller contact patch, which reduces grip, especially in wet or icy conditions.

🚨 Harsher Ride – More air means less cushioning, causing a rougher ride and extra strain on your vehicle’s suspension.

🚨 Uneven Tire Wear – Overinflation wears out the center of your tread faster, shortening the lifespan of your tires and costing you money.

🚨 Higher Risk of Blowouts – Too much pressure makes tires more vulnerable to sudden failure, especially on hot pavement or at high speeds.

The Bottom Line

Your vehicle’s recommended tire pressure isn’t a suggestion—it’s a key safety factor. Driving with properly inflated tires improves handling, enhances fuel efficiency, and keeps you safer on the road.

Before You Drive, Check Your Tires!

A quick pressure check before hitting the road can:
✅ Save you money on fuel and tire replacements
✅ Improve your ride quality
✅ Prevent unexpected blowouts and dangerous situations
