* The specific tire size: The sticker on your driver's side doorjamb (or your owner's manual) will list the recommended tire size for your vehicle. Different tire sizes require different pressures.
* The tire's load rating: Tires have different load ratings, affecting the recommended pressure. This information is printed on the tire sidewall.
* Whether you're carrying a load: More weight requires higher tire pressure.
How to find the correct pressure:
1. Check the sticker: The most reliable source is the sticker on your driver's side doorjamb. This sticker lists the recommended tire pressure for your vehicle's specific tire size and configuration. This is the pressure you should use for *normal* driving conditions.
2. Check the tire sidewall: The sidewall of your tire will also show the maximum tire pressure. Never exceed this maximum pressure.
3. Consult your owner's manual: Your owner's manual will have a section on tire pressure, providing additional guidance.
In short: Don't rely on a generic answer. Always check the sticker on your driver's side doorjamb for the recommended tire pressure. If you can't find the sticker, consult your owner's manual. Then, use a reliable tire pressure gauge to check and adjust your tires accordingly.
