Is a tire pressure of 195 kPa normal in cold weather?
1 Answers
A tire pressure of 195 kPa in winter is not normal. A pressure of 195 kPa is too low for winter, as it can easily damage the tire or cause a blowout. Due to thermal expansion and contraction, it's acceptable to have slightly higher tire pressure in winter compared to summer. Safe tire usage is crucial for driving, and most vehicles are equipped with tire pressure monitoring systems, so it's important to pay attention to it while driving. Hazards of overinflated tires: Reduced friction and adhesion of the tire, affecting braking performance; Causes steering wheel vibration and drifting, reducing driving comfort; Accelerates wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overstretches the tire cords, reducing elasticity and increasing the load on the tire during driving; Decreases puncture resistance. Sharp objects like nails or glass can easily penetrate the tire, causing internal cracks or blowouts. Hazards of underinflated tires: Increases friction with the road surface, leading to higher fuel consumption; Causes heavy steering and drifting, compromising driving safety; Increases movement of tire components, leading to excessive heat generation from over-flexing; Weakens the cords and rubber, causing delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; Dramatically increases friction with the ground, raising tire temperature, softening the tire, and drastically reducing strength. High-speed driving can lead to blowouts; Increases tire deformation, causing sidewall cracks and excessive flexing, leading to overheating, rubber aging, cord fatigue, and breakage, while also enlarging the tire's contact area and accelerating shoulder wear.
