The correct tire pressure for a car varies depending on the vehicle type, model, and brand. However, most passenger cars will recommend 32 to 35 psi in the tires when they are cold. The recommended tire pressure is a cold inflation pressure, which means the pressure check should be done after the vehicle has been sitting in the shade for a while. The recommended pressure can be found in the owners manual, on a sticker inside the drivers door, or on the rear edge of the door itself, in the glove box, or on the inside of the fuel-filler door. It is important to note that the pressures listed are for the tire size that originally came on the vehicle, and if different-sized wheels and tires have been installed, the listed pressures won’t necessarily be correct. It is also important not to inflate your tires to the pressure listed on the tire itself, as that number is the maximum pressure the tire can hold, not the recommended pressure for the vehicle. Over-inflating your tires will give you a bouncy ride and an ill-handling car, while under-inflated tires can develop premature wear from increased friction.
