Most normal passenger cars need around 30–35 psi (about 2.1–2.4 bar) in their tyres when cold, but the correct number for your car is on the sticker/plate on the vehicle and in the owner’s manual, not on the tyre itself. Always use that sticker value as your main reference.

Quick Scoop

Short answer:

  • Check the sticker in the driver’s door jamb (or fuel flap / owner’s manual). That is your car’s official tyre pressure.
  • For many everyday cars this is usually in the 28–36 psi range when tyres are cold, and often 32–35 psi for typical passenger cars.
  • Set pressures when the car has been parked for a few hours, not straight after driving, because heat raises the reading by roughly 2–6 psi.

Where to find the exact number

  • Driver’s door area: Most modern cars have a sticker in the driver’s door jamb showing front and rear tyre pressures, often with separate values for “normal load” and “full load”.
  • Owner’s manual: The “tyres/wheels” or “maintenance” section repeats the recommended pressures and sometimes gives motorway or fully‑loaded recommendations.
  • Other spots: Some manufacturers also put the info on the fuel filler flap, in the glovebox, or under the bonnet, and tyre shops and online databases can look it up by registration or model.

Important: The number on the tyre sidewall is a maximum pressure the tyre can safely handle, not the pressure you should inflate to for your car.

Typical ranges (just as a guide)

These are generic examples only — always defer to your sticker/manual.

  • Small city cars: often around 30 psi front and rear when cold.
  • Medium hatchbacks/saloons/SUVs: commonly in the 32–36 psi region.
  • Larger or heavily loaded vehicles: may specify higher pressures, sometimes above 36 psi.
  • Performance or special tyres: can have quite specific front/rear splits tuned for handling, so the sticker matters even more.

Why getting it right matters

  • Safety and grip: Under‑inflated tyres run hotter, can deform more in corners, and increase stopping distances; over‑inflated tyres reduce the contact patch and grip.
  • Fuel economy: Correct pressure reduces rolling resistance so the engine works less and fuel use drops.
  • Tyre life and comfort: Too low chews the outer edges; too high wears the centre and makes the ride harsher and noisier.

How to set and check your pressures

  1. Let the car sit for a few hours or do only a very short, slow drive so the tyres are “cold”.
  1. Read the front and rear values from the door sticker/manual (they may differ front vs rear, and for heavy loads).
  2. Use a reliable gauge at a petrol station or a home inflator to set each tyre to the recommended cold pressure.
  3. Recheck monthly and before long trips or heavy‑load driving; adjust if temperatures have changed a lot with the seasons.

If in doubt, slightly low or high relative to the sticker (within about ±3–4 psi) is usually acceptable, but consistently running far below or above the recommendation is not.
