he tire pressure when it comes to cars, is of essential importance. Car tires, in fact, represent the only point of contact of the vehicle with the asphalt and having the right pressure can affect not only the performance of the vehicle, but often also its behavior. Maintaining the pressure of the car tires between the values indicated by the house, therefore, can also help in driving. But how can we maintain the ideal pressure even when the cars are stopped? Here are some tips to avoid tire damage or deformation.
WHAT IS THE IDEAL TIRE PRESSURE
The ideal tire pressure varies from vehicle to vehicle and is always indicated on the car ‘s registration document . Furthermore, the same data is always reported inside the door. If the car stays in the garage for a long time, as in this period with movement restrictions due to the Covid-19 epidemic, the pressure bars may drop. For this reason, experts always recommend slightly increasing the tire inflation pressure from 0.2 to 0.5 bar more depending on the mass of the vehicle and the parking time.
Technology, in this case, comes to the rescue: the most modern cars, in fact, are equipped with the so-called tire pressure sensor which turns on when it is too low. If this happens, just go to the tire dealer or any distributor to inflate them. In doing so, it is good to inflate the tire cold since the heat modifying the values of the pressure gauge which measures the pressure.
CARS STOPPED, HOW TO AVOID THE FLAT SPOTTING EFFECT
One of the drawbacks caused by stopping the car is that of flattening the rubber, also called “flat spotting”. This can be of two types: temporary or semi-permanent. The extent of the phenomenon, as pointed out by the Continental experts, depends on size, load, internal structure, ambient temperature and duration of the stop. When a vehicle is left stationary for a few days or weeks, it is normal for vibrations to be felt during the first few kilometers of driving. In these cases, the flattening is destined to disappear once the tires have reached operating temperature and regained their normal shape.
If the period of time extends to a month or more, on the other hand, it is likely that a semi-permanent flattening may occur which, especially if combined with high temperatures and low tire pressure, can cause a more severe ovalization condition, cannot be resolved with normal vehicle reuse. An effective strategy to prevent flat spotting from occurring in these cases is to maintain correct tire pressure, because when they are deflated they tend to flatten more easily.
