What pressure should my tires be?

Use the PSI on the driver’s door sticker (or fuel-filler placard) for your vehicle load — not the maximum printed on the tire sidewall. Hazlehurst Tire Company — call 601-894-3396.

Why does pressure change with the weather?

Air expands when hot and contracts when cold. A cool morning after a hot Mississippi day can drop several PSI. Check when tires are cold for the most accurate reading.

What does under-inflation do?

It builds heat, wears the outer tread, hurts fuel economy, and can lead to failure. Over-inflation wears the center and rides harsher. Aim for the sticker value.

Correct pressure is on the door sticker — not the sidewall max. Mississippi heat and cold mornings both move the needle; under-inflation burns tread and fuel.

Tire pressure is simple maintenance that most people skip until the dash light comes on. Keeping it right protects tread life, fuel economy, and safety.

Where to look

The correct cold PSI is on the door jamb sticker. The number on the tire sidewall is a maximum for the tire — not your vehicle’s recommended setting.

Heat and cold around here

Hot pavement and summer heat raise pressure after you drive
Cool mornings drop pressure — check before a long trip
Don’t bleed air out of a hot tire to “fix” a high reading

TPMS isn’t a substitute for a gauge

The warning light means something’s wrong — often low pressure, sometimes a sensor. We can set pressures, inspect for leaks, and service TPMS when a sensor fails.
