* Tire size: Different tire sizes require different pressures. Your tire's size is printed on the sidewall (e.g., P215/60R16).
* Load: The sticker on your driver's side doorjamb (or inside the fuel filler door) will specify the recommended tire pressure for your vehicle's *typical* load. This is usually the pressure for normal driving with a few passengers and typical cargo. Higher loads require higher pressure.
* Whether you have a spare tire: Spare tires often require different pressures. Check the spare tire itself for its recommended pressure.
Where to find the correct information:
1. Driver's side doorjamb sticker: This sticker is the most reliable source. It lists the recommended tire pressure for your specific vehicle and tire size(s). Look closely; it might be on the edge of the doorjamb.
2. Tire sidewall: The maximum pressure for your tire is also printed on the sidewall. Never inflate your tires to this maximum; use the pressure specified on the doorjamb sticker as a starting point.
3. Owner's manual: Your owner's manual will have a section on tire inflation and maintenance.
Do not rely on general internet searches for tire pressure. Always use the information specific to your vehicle and tires as found on the doorjamb sticker or in your owner's manual. Incorrect tire pressure can affect your handling, fuel economy, and tire wear.
