* The specific year of your Silverado: Tire pressure recommendations change slightly from year to year.
* The specific trim level of your Silverado: Some trims might have slightly different recommendations.
* The size of your tires: The sticker on your driver's side doorjamb (or your owner's manual) will list the correct pressure for the *specific tires* on your truck. This is the most important factor.
Where to find the correct tire pressure:
1. Check the sticker on your driver's side doorjamb: This sticker provides the recommended tire pressure for your specific vehicle configuration. It's the most reliable source of information.
2. Consult your owner's manual: Your owner's manual will also list the recommended tire pressures.
3. Look at the tire sidewall: The maximum pressure for your tire is printed on the sidewall. Never inflate your tires to the maximum pressure listed on the sidewall. Always follow the recommendations from the doorjamb sticker or owner's manual.
In short: You must consult your vehicle's documentation (doorjamb sticker or owner's manual) to determine the correct tire pressure for your specific Silverado 1500 extended cab. Do not rely on a generic answer. Improper tire pressure can affect fuel economy, handling, and tire wear.
