Tyre pressure

Why should you take care of your tyre pressure?

For safety

  • Bridgestone’s study has shown that as much as 6% of all casualties in road accidents are caused by burst or punctured tyre or by pressure drop.
  • As the American National Highway Traffic Safety Administration says, insufficient tyre pressure extends the braking distance by 22 per cent.

For savings

  • Insufficient tyre pressure increases fuel consumption and significantly diminishes tyre durability.
  • A study in Canada has shown that correct tyre pressure gives an average driver two weeks of driving without refilling per year.
  • According to Bridgestone’s study, insufficient pressure may shorten the tyre’s lifespan by as much as 40 per cent.

For the environment

  • According to Bridgestone’s European Technical Centre, EU drivers have prematurely worn off 29.6 billion tyres and needlessly burned 3.9 billion litres of fuel in 2008 alone.This means they wasted 7.8 billion euro and released 9.2 megatons of CO2 into the atmosphere. The results came from a tyre review of 31178 passenger vehicles in 14 EU countries in 2008.

What causes tyre pressure loss?

According to the study by the American Department of Transport, low pressure is caused in 85% of cases by gradual, small but regular air leak, and only in 15% of cases by actual damage (e.g. hitting a curb).

What causes natural tyre pressure loss?

  • Incorrect assembly
  • Temperature
  • Small damage
  • Leaking valve or valve stem

How often should you check your tyre pressure?

The tyre pressure should be checked preventively at least once every two weeks, and must be checked once per month.


The information concerning correct tyre pressure is often located on the inside of the fuel cap.

How do I check the tyre pressure?

  • The tyre pressure should be checked in cold tyres.
  • Assessing pressure visually is not recommended, especially in tyres with profile lower than 65.
  • It's always better to go to a tyre repair shop or a petrol station.

What should my tyre pressure be?

As recommended by the manufacturer

Where can I find the tyre pressure recommended for my car?

Check our pressure chart and learn what pressure is recommended for your car.

The information concerning correct tyre pressure for your car can also be found:

  • On a sticker on the driver’s door pillar,
  • in the glove compartment,
  • on the fuel cap,
  • in your car’s manual.

Can I adjust the tyre pressure to suit my preferences?

Yes, within reason.Exceeding +/- 10% of the recommended value is not advisable.

When should I consider adjusting the tyre pressure?

  • when the load changes significantly,
  • when driving with a trailer,
  • when travelling a longer distance on a relatively even road, at high speed (slightly higher pressure reduces rolling friction),
  • when driving on bumpy city roads (slightly lower pressure will increase the comfort of driving on bumpy roads).

Note! Under no circumstances should you adjust the tyre pressure in only one tyre on one axle.
In such case, even the slightest difference (few per cent) in pressure between the left and the right wheel will “pull” the car left or right.
