Check tire pressure while the tires are cold

Read the vehicle’s pressure label, measure each tire, and adjust only to the specified value.

Why it matters: A dashboard warning is not a substitute for regular pressure checks.

Understand the job before starting

The vehicle’s specified pressure and the tire sidewall markings describe different things.

A common mistake to avoid

Using a hot-tire reading as if it were the specified cold check can mislead you.

Check your supplies

Use what you already have. Check each item when it is ready.

Before you begin

Park safely away from traffic. Stop for a bulge, cut, repeated pressure loss, or a visibly damaged tire. Do not use the maximum pressure printed on the tire as your vehicle’s target. Front, rear, and spare targets can differ.

STEP 1 OF 4

Find the vehicle’s targets

Start here: Copy your vehicle targets and units.

Check tire pressure while the tires are cold, step 1: Driver-door vehicle label and Front / rear / spare units. Copy your vehicle targets and units. Diagram is generic; follow the written directions and your own equipment instructions.
Example: Copy your vehicle targets and units. Follow the written step.
Read-aloud is available in supported browsers; the written steps always remain available.

Read the Tire and Loading Information label near the driver’s door or the owner’s manual.

Write the front, rear, and spare values separately.

Check the units; PSI and kPa are different measurements.

Before moving to the next step

Check this specific result: The targets come from the vehicle label or manual, with units recorded.

If that result is not true yet, leave the box unchecked. Write what is missing in your notes; use the official instructions below when the equipment or situation differs.

A SECOND WAY TO SEE IT

Watch a YouTube companion

Tire Pressure 101

By AAA · External video

What to look for: Watch locating the vehicle target and using a pressure gauge. Check cold tires and use the vehicle label, not the tire sidewall maximum.

Watch on YouTube (opens a new tab)https://www.youtube.com/watch?v=Oh1lvbQBJa0

How to use the video with this guide

Read “Before you begin” first. Watch the relevant part, pause, then return to the written step and its completion check. Use captions and playback speed if they help. A demonstration may cover only part of the task or show different equipment.

Your model’s instructions and current official guidance take priority. For urgent problems, follow the stop instructions without waiting to watch a video.

Finish the job and know what to do next.

For this guide, the final result is: Pressures match their vehicle-specific targets, or a damaged or leaking tire is referred for inspection.

A concrete way to approach this task

If the door label gives different front and rear values, copy both. The number on the tire sidewall is not the target for this car.

What if I cannot complete a step?

Repeated low pressure on the same tire needs a tire-service inspection, even if adding air clears the warning light.

Identify the exact step: “Find the vehicle’s targets.” Record what you tried, what happened, and which item or model you used. Ask for help with that specific problem rather than repeating an unsafe or unsuccessful action.

Park safely away from traffic. Stop for a bulge, cut, repeated pressure loss, or a visibly damaged tire. Do not use the maximum pressure printed on the tire as your vehicle’s target. Front, rear, and spare targets can differ.

Connect this skill to everyday life

Set a total purchase and running budget before shopping. Arrange an independent inspection and collect written terms for the specific vehicle.

A low monthly payment can come with a longer term or higher total cost. A vehicle history report is not a substitute for inspecting its current condition.
