Correct tire pressure for a car in hot weather, Photo: magnificHot summer days put extra strain on car tires. It is the wheels that ensure direct contact with the road surface and are responsible for driving safety. Temperature fluctuations cause pressure variations inside the rubber, so it is important to understand the physics of this process and avoid common mistakes.This is reported by Moto.
The Effect of Heat
The air inside the sealed volume of the tire expands due to the high ambient temperature. A change in air temperature of every 10°C can increase the internal pressure by approximately 0.1 bar.Additionally, tires heat up during driving from hot asphalt and the constant deformation of rubber.Read also

Therefore, measurements should only be taken after the car has been stationary for a long time. Releasing air from hot tires after a trip is strictly prohibited.The results obtained immediately after stopping will be significantly overestimated, leading to a dangerous drop in pressure after the tires cool down.
Finding the Parameters
Tire pressure standards are the same for any time of year and do not depend on the season. For most passenger cars, the optimal value ranges from 2.2 to 2.5 bar, but you should always follow the manufacturer’s specific instructions.The recommended figures are indicated on the sticker in the driver’s door frame, on the inside of the fuel tank cap, or in the owner’s manual.🚘 Doesn’t your car deserve the best?

You should not rely on this extreme value for daily driving.
Consequences of Deviations
Low pressure increases rolling resistance, causing the car to consume more fuel and handle poorly on turns.An underinflated tire overheats instantly, and its sidewalls wear out much faster. This significantly reduces the tire’s lifespan and increases the risk of a sudden blowout.Read also

Excessive pressure is also harmful, as it reduces the contact patch of the tread with the road and makes the suspension stiff. In this case, the central part of the tread wears out prematurely, and the car becomes sensitive to small potholes.
Inspection Rules
Experts recommend checking tire pressure at least once a month and before every long trip. It is best to do this in the morning using your own pressure gauge or a compressor at a gas station.All tires gradually lose air due to natural microscopic seepage through the rubber structure and valve core. Systematic monitoring remains the simplest way to save money and ensure road safety.According to: Novyny.liveSpace for your advertisement
