Tire Pressure

Check Tire PSI

Get recommended tire pressure for your car. View psi tire pressure chart according to your car wheel size and tire brand and do not forget checking production year of your car.

Importance Of Right PSI

Maintaining your tires is the most important thing you can do to insure the safety of your car on way.Driving on tires with incorrect air pressure, on the other hand, means disaster could strike any time - and at any speed.

The tire pressures specified for your vehicle are agreed to between the vehicle manufacturer and the tire producer. The psi (pound per square inch) is based on your vehicle's total weight and size, towing weight capability, and recommended tire size.

Tires also have a 'tread wear indicator' block set into them at a depth of 1.6mm. You should check this block to ensure that this indicator is not at the same level as or lower than the tyre tread.

How To Check PSI AIR PRESSURE USING A PRESSURE GAUGE DEVICE ?

Regardless of the types, using a tire pressure gauge is relatively easy. It only involves a few basic steps which consist of the following.

1. Take the cap of the tire valve. To do this you need to unscrew the valve stem or the black extension near the hubcap disk on the wheels.
2. Attach the gauge. As to how to connect the instrument to the tire may slightly vary depending on what type of gauge you are using. For dial gauge, attach the valve end of the over the valve press system. If its a stick gauge, you need to take the open end of the stick gauge first before you can attach it to the tire's valve.
3. Press the gauge against the tire nozzle. Do make sure no hissing sound is heard. Otherwise, this translates to air pressure escaping which could result in an inaccurate reading.
4. Compare the measured psi to the psi found on the sticker inside the driver's door of your vehicle or in owner's manual. DO NOT compare to the psi on your tire's sidewall or PSITirePressure.com value.
5. Replace the valve cap. The valve stem cap has a rubber seal designed to trap dirt and moisture away from the valve stem core that holds the air for your tires. Without the valve cap, air pressure escapes out of your tire and you'll end up with a flat tire.

Temperature Relation On Tire Pressures

Just as cold outside air causes the air inside your tires to contract in winter, warm outside air causes the air inside your tires to expand. The rule of thumb (best understood as our American counterparts put it) is that tire pressure will go up approximately one pound per square inch (PSI) for every 10 Fahrenheit increase in temperature. So, let's say your manufacturer's recommend inflation level is 35 PSI, on one of those all-time hot August afternoons, your tire pressure could be somewhere near 40 PSI.

Tire PSI Inflation Types:

Proper inflation: Properly inflated tires will have an equal distribution of tire tread contact with the road. This creates evenly distributed wear for the entire tire, allowing a smoother and safer ride.

Under inflation: Under inflated tires are caused by having little air pressure, which affects the outer tread edges, making them the only contact the road. This creates wear primarily on both edges of the tire tread, with less wear in the center.

Over inflation: Overly inflated tires are caused by having too much air pressure, this directly affects the tire's middle section, being the only point of contact to the road. This creates wear primarily in the center of the tread, with less wear at the tire's edges.
