It is extremely important in terms of traffic health that vehicles move on the road without any accidents and trouble. For this, we have to follow the traffic rules. But at the same time tire on vehicles pressure must be in the right size. The pressures of the vehicles should be checked within an average of 15 to 30 days. A tire loses some of its pressure [about 1 psi per month (0.076 bar)] due to natural causes. Pressure loss can be accelerated by other air leaks for the following reasons:

  • Accidental tire puncture
  • Valve: The tire must be changed every time it is changed.
  • Valve cover: important for air tightness.
  • Rim: It should be cleaned every time the tire is fitted.
  • Follow the recommendation of the vehicle or tire manufacturer, especially regarding the conditions of use (load / speed etc.).
  • Check the tire pressure when the tires are cold [after not used for the last 2 hours or used less than 3 km at low speed]
  • If the tires are hot when inspected, add 4 to 5 psi (0,3 bar) to the pressure recommended by the vehicle manufacturer. Once the tires have cooled, check the pressure again.
  • Never bleed a hot tire.
  • Even if the tires are inflated with nitrogen, the tire pressure and general condition of the tires should be checked frequently.

A correctly inflated tire increases safety, is more economical and is more environmentally friendly.

How Do I Check Tire Pressure?

  1. Place the tire pressure gauge inside the valve stem of your tire.
  2. The device will go out and display a number expressing the internal pressure in psi.
  3. The whistling sound is caused by the air the tire has missed. It will not greatly affect the pressure unless you press the pressure gauge for a long time.
  4. Compare the measured psi / bar value to the recommended psi / bar value.
  5. If psi / bar is higher than recommended, blow off air until it is equal. - If it is low, inflate the tire until it reaches the proper value.

Where Can I Find the Recommended Pressure for My Tires?

  • In the vehicle owner's manual
  • On a sticker on the driver's door or fuel filler flap
  • Do not use the number on the sidewall of your tire, as this number does not represent the pressure required for your tire.

Pressure Measuring Instruments

  • Be careful when using pressure gauges offered at gas stations. These devices are generally unreliable.
  • Purchase a high quality pressure gauge and have a tire specialist check that it measures correctly.

Finding the Right Value is Important

  • Under-inflated or over-inflated tires may wear faster than expected, have less grip, and consume more fuel. Taking a few minutes a month ensures your safety and extends the life of your tires.

What Should the Tire Pressure of Vehicles Be?

Tire pressure in vehicles must be in the right size. We tell you the tire pressure of your vehicle according to the tire size:

  • Tire size 175/65 R14: Front 2,31 - Rear 1,8
  • Tire size 195/50 R15: Front 2,1 - Rear 1,8
  • Tire size 195/45 R16: Front 2,2 - Rear 1,8
  • Tire size 205/40 R17: Front: 2,2 - Rear 1,8
  • Tire size 195/60 R15: Front: 2,1 - Rear 2,1. However, these pressures are valid for normal loaded tires.

Should All Tires Have The Same Pressure?

People who pay attention to vehicle tire pressures wonder if all tires are the same. Tire pressures may vary depending on the load condition of the vehicles. Apart from the load, there are some factors that need to be considered, but you can base the load on pressure. The load distribution of cars with front hammer is more than the front. For this reason, the front air pressure must be higher than the rear. For example, cars such as BMW and Mercedes have a front hammer. If you have such tools, you can adjust their pressure accordingly.

Front and rear tire pressures are almost very close to each other in cars with rear wheel drive. However, the front tires should be slightly more than the rear.

What Happens With Low Tire Pressure?

The tire pressure of the vehicles must be directly proportional. The correct pressure of the vehicle tires must be in line with your vehicle tire pressure for both your safety and a healthy traffic experience. Apart from that, we can express the damages that a low tire pressure can cause you as follows:

  • Your handling ability will decrease.
  • Your steering control will decrease.
  • Your braking distance will decrease in wet conditions.
  • Because the tires will get too hot, there will be a risk of explosion.

As you can see, low tire pressure can cause serious consequences. Therefore, having the right pressure for your tire type will be very important for a healthy and accident-free road experience.

Accordingly, even if the tire pressure is too high, abrasion will occur on the tires. This will cause a rapid decrease in tire life.
