Properly inflated tires can give you better gas mileage and prolong the tire life, however, not everyone knows what is the recommended tire pressure for their vehicle. In this article, we will introduce how to find the recommended tire pressure for your vehicle.
How to check?
Your car has a recommended tire pressure that will give the best gas mileage, handling, and tire life for that car — and it’s written right on the vehicle’s door. That’s the one you should follow when filling them up with air to the recommended pressure, measured in pounds per square inch or psi.
On newer cars, the recommended tire pressure is most commonly listed on a sticker inside the driver’s door. If there’s no sticker on the door, you can usually find the specs in the owner’s manual. Most passenger cars will recommend 32 psi to 35 psi in the tires when they’re cold. The reason you check tire pressure when they’re cold is that as tires roll along the road, friction between them and the road generates heat, increasing both the temperature and the air pressure. For the most accurate reading (not to mention the most consistent one), make sure the car has been sitting overnight or at least has been parked for a few hours.
Do not inflate your tires to the pressure listed on the tire itself. That number is the maximum pressure the tire can hold, not the recommended pressure for the vehicle. Tricky, huh?
Overinflation of your tires will give you a bouncy ride and an ill-handling car while driving on underinflated tires can cause premature wear from increased friction. Either way, not having your tires inflated to their recommended pressure will negatively affect tire wear and vehicle performance — and will definitely affect your maintenance schedule when it comes to replacing them.
