All You Need to Know About the Correct Tire Pressure


Most drivers know that checking tire pressure periodic can prevent breakdowns while ensuring the correct performance of your car on the road.

If the tire pressure is inappropriate, it may cause tire wear and perhaps increases the possibility of tire blowout by producing deformations in the tire. Low tire pressures increase braking distance. The braking distance to go from 90 kilometers per hour to 70 kilometers per hour is 40 meters at 2.0 bars. But with 1.0 bar, this distance is extended to 45 meters, braking 5 meters further. Low pressure in the tires leads to aquaplaning.

Another significant factor is the fuel consumption due to the effect of low pressure on the rolling resistance. The tires with 1 bar less inflation pressure than the recommended have a higher resistance to rolling, which can mean 6% more fuel consumption.

Excessive tire pressure also reduces the safety of driving, since contact with the road surface is insufficient. Besides, the tread of an overinflated tire will wear much faster in the center and will be more vulnerable in case it’s driven on a poor road.

What’s the Correct Tire Pressure?

Although the general idea is that the tire pressure must be around 2.5 bars, the truth is that everything depends. The ideal pressure for each tire is suggested by the car manufacturer which determines the pressure that must be applied to them.

You have got the information for each specific model in the car manual and on the fuel tank lid or the driver’s door pillar. Typically, two pressures are indicated: one for normal driving conditions & another for the vehicle in full load. The maximum inflation pressure of the tire also appears on the tire sidewall.

How often do you have to Measure Tire Pressure?

The tires lose pressure as usual — approximately 0.069 bars per month, a figure that also increases with the increase in temperatures. In fact, during the summer, the pressure can drop by half a kilo for each 10ºC decrease in temperature. For what is recommended, review it at least once a month.

How to Measure the Pressure?

Use a tire pressure gauge to measure the pressure that you’ll find in service stations. Unscrew the valve plug and place the manometer on it. Compare the gauge pressure with the recommended bar or psi value for your tire and add more air with the compressor if necessary.

Check all tires, including the spare. If the pressure of the tire plummets, go to a workshop because it is likely that there was a problem in the adjustment of the tires or a defect in the valves. So when you buy the new set of car tyre in Lebanon, be mindful of these useful tips.

Remember that it is imperative to measure the pressure of the tires when they are cold – for instance; first thing in the morning or perhaps after travelling a few kilometers.

What if my Car has a Trailer?

In case you have trailers, it’s good to increase the pressure of the rear tires of the car to 0.4 bars. Correct tire pressure is essential for a safe & comfortable driving while avoiding wear and ensuring road grip of your tires Lebanon.
