How do you check your tire pressure?
Briefly press the small dot or bead on the back of the tire pressure gauge into the center of the valve stem on the tire. You should hear the air escaping the tire. Use the gauge to check the tire pressure. Repeat these steps until you’ve released enough air to reach the correct psi.
Why is it important to check your tire pressure?
Since most tire damage and wear is a result of driving on tires that are improperly inflated, tire experts suggest checking your air pressure once a month. Tires that are not at the correct air pressure will also increase the rolling resistance (the friction that occurs when an object rolls) of the vehicle.
Why do you have to check the tire and tire pressure before driving?
Here are the five other reasons you need to check the pressure in your tires. 1. Helps optimize tire performance and fuel economy (something especially useful with the AC running all the time and the increasing gas prices). Stabilizes the tire’s structure, blending the tire’s responsiveness, traction and handling.
How do I check my tire pressure without a gauge?
Hand Pressure You can check your tire pressure with your hands as well. Push your hand down onto the tire. If the tire feels soft and squishy, the tire pressure is low. If the tire feels rock hard, meaning you are unable to push down on the tire at all, then it is overinflated.
Why do mechanics over inflate my tires?
The short answer is that when they service and change your oil the tires are generally hot. The PSI in your door is for cold (car has sat overnight). If your tires are hot the pressure will be higher than cold. Thus when they fill the tires they do so to the appropriate “hot” level.
Is it best to check tires when cold?
Tire manufacturers suggest checking tires when they’re cold for the most accurate reading. Outside temperatures can cause tire pressure to vary by as much as 1 psi per 10 degrees; higher temperatures mean higher psi readings.
Where do I go if my tire pressure is low?
If your TPMS warning light does come on, find the closest gas or service station and check the pressure of all four tires (plus the spare, if applicable), adding air to any that fall below the range listed on a sticker inside the driver’s door.
What causes tires to lose pressure?
Slow leaking punctures in the tread are the leading cause of tires losing air. A nail embedded in a tire’s groove may cause a loss of 2 or 3 PSI per day, not 2 or 3 PSI per month as with osmosis. Leaking valve stems and cores are another cause of low tire pressure. Over-tightening valve cores can lead to loss of air.
Do you know how often should you check your tire pressure?
Most experts recommend that you check your tire pressure at least once per month. This is because tires tend to lose (on average) about 1 PSI per month through the natural process of air molecules escaping through the tiny “pores” in the tire wall.
What’s the correct way to check tire pressure?
Find the recommended pressure for your tires. You’re looking for a two-digit number followed by ‘PSI’ (pounds per square inch).
Why should tire pressure be checked?
Tire pressure has to be checked periodically to assure that the influences of time, changes in ambient temperatures or a small tread puncture have not caused it to change. The tire pressure recommended in your vehicle’s owner’s manual or tire information placard is the vehicle’s recommended cold tire inflation pressure.
How often do you need to check your tires?
For this reason, it is important to check your tires well ahead of long trips and at least once a month. The best time to check your tires is in the morning or when they are cold. When the tires are hot, the air inside tends to expand result in higher readings than normal pressure.
