Maintaining correct inflation pressure is essential and avoids premature or uneven wear. As tyres naturally lose pressure over time, you need to refill them regularly. Driving on the correct tyre pressure will extend the life of your tyre, improve vehicle safety and maintain fuel efficiency.

Check your tyre pressure at least once a month, when your tyres are cold, and before long journeys.

STEP 1: Make sure the tires are cold. This means that the vehicle hasn't been driven for more than 2 kilometers (1.2 mi). Checking air pressure in cold tires ensures that the air hasn't expanded from heat, giving you a more accurate reading.

STEP 2: Look in the owners' manual or on the inside of the driver's side door for the standard cold tire inflation pressure. This number is the lowest PSI one would inflate the tires to and is suggested by the car's manufacturer. Read below for reasons inflation may be placed higher.

 Also note that the front and back tires may need different pressures, according to the manufacturer.

 STEP 3: Unscrew the valve stem cap from the valve stem on the tire. The valve stem is a black pencil-sized extension near the hubcap, about 1" (2-3 cm) long.

STEP 4: Press the air pressure gauge evenly onto the valve stem and record the reading given. If there is a hissing sound, the gauge is not tight or even enough for an accurate reading. The angle of the gauge may need to be adjusted.

If you are using a digital model gauge, you may or may not need to press a button in order for the gauge to read the air pressure. If you are using a traditional gauge, the metered stick should give you a reading automatically.

STEP 5: Replace valve stem cap. The cap does not hold air in, but it keeps dirt and moisture away from the valve mechanism in the valve stem, which does hold air in.

•Read the measurement on the gauge.

•To add air, pump gauge until correct pressure is shown. To deflate, depress the tyre valve.


 More tread means more grip. It’s as simple as that. Be aware that even though the legal limit is 1.6mm, anything under 3mm can seriously compromise performance and safety.



The tyre label is a grading system through which manufacturers of tyres for cars, vans, and heavy trucks must specify:

Fuel consumption
Wet grip
Noise classification

As shown below, the tyre label uses a classification from A (highest performing) to G (lowest performing). Information must be available in technical promotional literature (leaflets, brochures, etc.), including manufacturer websites. This has to be done for every new tyre within scope of the regulation sold on the EU market.
