* Tire size: The sticker on your driver's side doorjamb (or in your owner's manual) will list the recommended tire pressure for your specific tire size when the vehicle is properly loaded.
* Load: The recommended pressure will be higher if the vehicle is heavily loaded with passengers or cargo. Again, check the sticker on the doorjamb for the appropriate inflation for different load conditions.
* Tire condition: If your tires are older or damaged, they might need slightly higher pressure.
* Ambient temperature: Temperature affects tire pressure. Colder temperatures mean lower pressure, and hotter temperatures mean higher pressure.
Where to find the correct information:
1. Driver's side doorjamb: Look for a sticker on the driver's side doorjamb. This is the most reliable source of information. It will specify the recommended tire pressure for your vehicle and tire size, typically for both normal load and maximum load conditions.
2. Owner's manual: Your owner's manual should also contain this information.
3. Tire sidewall: The maximum pressure for your tire is printed on the sidewall. *This is not the recommended pressure, but the maximum allowable pressure.* Never inflate your tires beyond this maximum.
Do not rely on a generic answer. Always check the sticker on your driver's side doorjamb or your owner's manual for the correct tire pressure for your specific 2001 Chevy Suburban 2500 and tire configuration. Using the incorrect tire pressure can negatively impact your fuel economy, handling, and tire wear.
