What is the correct psi for my tires car?
PSI, or pounds per square inch, is the standard unit used to inflate tires. The correct pressure for your car is prescribed by the manufacturer and can vary by model, tire size, and load. Locate the official cold- tire-pressure specification on the driver’s door placard or in the owner's manual and inflate accordingly. Do not inflate to the tire’s maximum sidewall pressure, which is not the target for everyday driving.
How to find the correct psi for your car
Use the steps below to identify the exact value for your vehicle and understand how to apply it in real-world driving.
- Look for the door placard: A sticker on the driver's door jamb (or inside the fuel-filler door) shows the recommended cold tire pressure for the front and rear tires, and sometimes for the spare as well.
- Consult the owner's manual or the manufacturer’s website for the official specifications for your exact model and tire size.
- Know the difference between the recommended pressure and the tire’s maximum sidewall pressure: the max on the sidewall is the highest safe pressure for full load, not the target for daily use.
- If you can’t find the information on the vehicle, contact a dealer or tire shop with your VIN or tire specifications to confirm the correct psi.
In most cases, following the door placard provides the proper values for everyday driving and efficiency, with adjustments possible for heavy loads or high-speed conditions.
Common ranges by vehicle type and tire type
These general guidelines help you verify that your numbers make sense, but always rely on the placard for your exact model and tire size.
- Passenger cars and most sedans: commonly 30-35 psi for both front and rear tires, with exact values shown on the placard.
- Small SUVs and crossovers: typically 32-40 psi, depending on tire width and load; check the placard for the precise per-axle numbers.
- Light trucks and vans: often higher, around 40-65 psi; exact values depend on load, tire type, and vehicle specifications.
- Performance or low-profile tires: may require higher pressures within the vehicle’s recommended range; verify with the placard and tire specifications.
Remember that operating pressures should align with the vehicle’s specifications; underinflation or overinflation can negatively affect handling, wear, and fuel economy.
Seasonal and operational considerations
Tire pressures change with temperature and load: cooler ambient temperatures tend to lower tire pressure, while hot conditions can raise it. Inflate tires when they are cold, and adjust for heavy loads or high-speed driving within the recommended range. If you see uneven wear or misshapen tires, recheck the pressures and consult a professional.
Summary
The correct tire psi is the value listed on your vehicle’s manufacturer placard or in the owner's manual for cold tires. It varies by model, tire size, and load, and may differ between front and rear axles. Use a reliable gauge to check when tires are cold, inflate to the specified numbers, and avoid relying on the tire’s maximum sidewall pressure. Regular checks help safety, performance, and efficiency.
