How do I check the air in my tires? How do I know the correct tire pressure? I’m not sure how to use those air pumps at gas stations.

Read this blog to learn how to use a gauge or fill the tires at the gas station and where to check how much air you need in your tires in summer vs. winter. Better still —- he can tell you where to get them checked and filled for free!

This is a great question especially this time of year when the temperature is changing and tire pressure is affected. Some of you may be seeing an indicator on your dashboard. How do I check the air in my tires? How do I know the correct tire pressure? I’m not sure how to use those air pumps at gas stations.

Some of you may be seeing an indicator on your dashboard indicating tire pressure is low: a symbol that looks like an exclamation mark inside brackets or parentheses (pictured here). tire symbol It is important to address low tire pressure as it affects gas mileage and will cause uneven wear and other conditions. If tire pressure is too low, then too much of the tire’s surface area touches the ground, which increases friction between the road and the tire. As a result, not only will your tires wear prematurely, but they also could overheat. Overheating can lead to tread separation — which could cause a serious accident.

tire gaugeOne option is to buy a tire pressure gauge. This is a handy gadget that will tell you the tire pressure in each tire.

The second option is to use air pumps at a local gas station. Some stations have attendants that will assist you while others charge (usually quarters).

Before you use a tire pressure gauge or go to a gas station, you should confirm what your recommended tire pressure is. To find that information, open the driver’s side door and look at the information on the label in the door jam.

How to use the gas station air pumps:
1. Remove the cap or stems from the tire valve on the tire(s) you want to check, one at a time.
2. Use your tire gauge to check the air pressure in the tire.
3. Use the air hose to add air in short bursts.
4. Keep checking the pressure until you get it right.

If you’re not sure how to use a tire pressure gauge, place the pressure gauge on the valve stem and press down hard enough so the hiss sound disappears and your gauge provides a reading. With a standard gauge, the air pressure will push a small bar out from the bottom of the gauge.

If you would like to have your tires checked and filled by a professional or certified technician, make sure to stop at a dealership like Jaffarian Volvo Toyota. We will be happy to check it for you Monday through Saturday. We’re just two minutes off Route 495, Exit 49 (River St. exit) at 600 River St. in Haverhill. It is a good idea to have your vehicle serviced as the weather changes and get your tires and your brakes checked. Drive safely.
