Tire Pressure Myths Debunked: Why ‘Just Fill It to the Sidewall’ is Wrong
NaTasha Brand • July 22, 2025
San Angelo, Texas — we need to talk. About tires.

Yes, those round rubber things on your ride. Specifically, we’re talking about tire pressure and the myth that just refuses to die: “Just fill it to the pressure on the sidewall.”
Here’s the cold, inflated truth: the pressure printed on your tire’s sidewall is the maximum it can safely handle—not the pressure your vehicle needs. That number is more like a "do not exceed" speed limit on the highway of tire inflation. It's not a recommendation—it's a warning.
Myth Busted: Sidewall ≠ Recommended Pressure
The correct tire pressure for your vehicle isn't a one-size-fits-all deal. It's tailored to your car’s weight distribution, suspension, and handling specs. You'll find the real numbers on a placard inside your driver-side door or in your owner’s manual. Trust us, that’s what the engineers designed your ride for—not some generic number molded into a tire.
Why It Matters in San Angelo
In a place like San Angelo, where temps can go from “sweater weather” to “Texas toast” in a single afternoon, proper tire pressure isn't just good advice—it’s essential.
Let’s break it down:
🔧 Fuel Economy
An under-inflated tire increases rolling resistance—basically, your car has to work harder, and that means burning more gas. With prices climbing faster than a jackrabbit on a hot griddle, you want every MPG you can squeeze out.
🔧 Tire Longevity
Too much pressure = center wear.
Too little = shoulder wear and heat build-up.
Either way, you're shortening the life of your tires and tossing money down the pothole.
🔧 Safety First
Improper tire pressure can lead to blowouts, hydroplaning, and longer stopping distances. Especially during sudden rainstorms or high-speed highway travel, your tires are the only thing between you and the pavement. You want them performing at their best.
