* Tire size: Different tire sizes have different recommended pressures. The sticker on your driver's side doorjamb (or inside the glovebox) will show the recommended tire size for your specific vehicle.
* Load: The vehicle's load capacity affects tire pressure. Higher loads require higher pressures. The sticker on the driver's side doorjamb will also give guidance on this.
* Whether you're checking the cold or hot pressure: Always check tire pressure when the tires are cold (meaning the car hasn't been driven for at least three hours). Hot tires will show a higher pressure reading.
To find the correct tire pressure for your 1992 Buick LeSabre:
1. Locate the sticker: The most reliable information is on the sticker affixed to the driver's side doorjamb or inside the glovebox. This sticker will list the recommended tire pressure for your specific vehicle and tire size.
2. Check the tire sidewall: The tire sidewall will have information printed on it, including the maximum pressure. This is the *maximum* pressure the tire can handle, not necessarily the recommended pressure for your vehicle. The recommended pressure will be significantly lower.
3. Consult your owner's manual: Your owner's manual should also specify the recommended tire pressures.
Do not rely on general online information. The information on the sticker in your car is crucial because it's specific to your model and year. Using the wrong tire pressure can affect handling, fuel economy, and tire wear.
