It's important to follow the manufacturer's recommendations for tire pressure, as indicated on the placard located on the driver's side door jamb or in the owner's manual. This information is specific to your vehicle and takes into account factors such as the vehicle's weight, tire size, and intended performance.
If a mechanic recommends a different tire pressure, there could be a few reasons for this, and it's worth clarifying with them. Here are some possible explanations:
Performance Preferences: Some individuals, including mechanics, might suggest higher tire pressures for reasons related to handling or fuel efficiency. However, it's crucial to strike a balance, as excessively high pressures can lead to a harsh ride, uneven tire wear, and reduced traction.
Temporary Adjustments: In certain situations, such as carrying a heavy load or towing, it might be recommended to temporarily increase tire pressure to accommodate the extra weight. However, this should be done in accordance with the vehicle manufacturer's guidelines.
Miscommunication or Mistake: It's possible that there was a miscommunication or mistake. Always double-check with the mechanic and ensure that they are aware of the manufacturer's recommended tire pressure for your specific vehicle.
Different Tires: If your vehicle has non-standard tires that differ from the ones it came with, the recommended tire pressure might also be different. Ensure that the mechanic is taking into account the specifications for the particular tires on your vehicle.
In general, it's best to adhere to the tire pressure recommended by the vehicle manufacturer. Deviating significantly from these recommendations can affect the vehicle's handling, fuel efficiency, and tire wear. If you have concerns or questions, consider seeking a second opinion or consulting with the vehicle manufacturer or another reputable mechanic.
