What Should My Tire Pressure Be?

Your tire pressure should match the vehicle door label for your tire size. There is no universal PSI that is safe for every car.

Short answer

The correct tire pressure is the recommended cold PSI on your vehicle's door label or owner manual. Typical passenger-car labels often fall somewhere in the low-to-mid 30s PSI, but that range is not a number you should set without reading your own placard.

This site will not publish a fake model PSI. Two cars with the same name can leave the factory on different sizes, and a replacement tire does not change the vehicle's recommended pressure unless the manufacturer published a new combination.

If your current tires differ from the size on the label, you still start with the vehicle placard and the tire maker's guidance for that size on that vehicle. Do not 'split the difference' between sidewall max and the old label.

Load matters. A fully packed SUV or a car pulling a trailer may have a higher listed pressure. Use the loaded column when the placard has one. When in doubt, stay with the published passenger listing and avoid overloading.

Use the calculator only after you have a real target and a real reading. The tool subtracts; it does not invent the first number.

Step-by-step

  1. 1Find the door-label cold PSI for your exact vehicle.
  2. 2Confirm the tire size on the car matches a size the label discusses.
  3. 3Measure the current pressure with a gauge.
  4. 4Use the calculator to see the gap.
  5. 5Inspect instead of calculating if a tire keeps losing air.

Common mistakes

Wanting one number for all cars The label exists because vehicles differ.

Averaging internet answers Those answers skip trim and tire size.

Setting sidewall max 'to be safe' Overinflation is not a safety upgrade.

Safety notes

If the only number you can find is the sidewall max, you do not yet have a recommended pressure. Get the vehicle documents or a dealer lookup.

FAQ

Why won't this site just tell me 35 PSI? Because that would be a guess for your car.

What if I installed plus-size wheels? Use manufacturer or tire-maker guidance for that setup, not a forum average.
