* Tire size: The sticker on your driver's side doorjamb will specify the recommended tire pressure for your specific tire size. This is the most reliable source of information.
* Tire load rating: Heavier-duty tires will often have a higher recommended pressure. This is also usually indicated on the tire sidewall.
* Whether you're carrying a load: If you're carrying passengers or cargo, you may need to increase the pressure slightly, again referencing the sticker on the doorjamb.
To find the correct tire pressure:
1. Check the sticker on your driver's side doorjamb. This sticker shows the recommended tire inflation pressure for your specific Mustang model and tire size. This is the most accurate information.
2. Check the tire sidewall. The maximum pressure is usually marked on the sidewall of the tire. *Never inflate your tires above this maximum pressure.*
3. Use a reliable tire pressure gauge. Don't rely on the gas station air pumps' gauges; they're often inaccurate.
In short: There's no single answer. Consult the sticker on your driver's side doorjamb for the most accurate information.
