How TPMS Sensors Work & Why They’re Critical in Houston Heat

Your Tire Pressure Monitoring System (TPMS) is one of those features you don’t think about until the light pops up on your dash. But here in Houston, where summer heat can push pavement temps above 140°F, TPMS isn’t just a convenience — it’s a safety essential.

What Is TPMS and How Does It Work?

TPMS sensors sit inside your wheels and constantly monitor air pressure in your tires. If the pressure drops too low (usually 25% below the recommended level), the system sends a warning light to your dashboard.

There are two main types:

• Direct sensors – mounted inside the wheel, giving real-time, accurate readings.

• Indirect systems – use your ABS system to estimate pressure based on wheel speed.

  Most modern vehicles use direct sensors.

Why TPMS Matters More in Houston

Houston’s hot weather and rough roads put extra stress on your tires:

• Heat causes pressure swings – A tire can gain or lose 1 PSI for every 10°F change. That means a tire that’s fine in the morning may be underinflated by afternoon.

• Low pressure = danger – Underinflated tires run hotter, wear faster, and are more likely to blow out on the freeway.

• Fuel economy suffers – Just a few PSI low can cut gas mileage, and with today’s fuel prices, that adds up fast.

  Without working TPMS sensors, you might not catch these issues until it’s too late.

Common TPMS Problems

• Dead batteries inside the sensor (usually last 5–7 years)

• Sensor damage during tire changes

• Corrosion from Houston’s humidity and rain

If your TPMS light is on and doesn’t reset, it’s time to have your sensors inspected.

The Bottom Line

In Houston heat, TPMS sensors aren’t just about convenience — they’re about safety, fuel savings, and extending tire life.

At Tires Wheels Sensors – TWS, we specialize in TPMS sensor replacement, resets, and diagnostics. If that light’s on, don’t ignore it — stop by for a quick check and keep your ride safe.
