Is 260 kPa Tire Pressure Too High in Winter?
2 Answers
260 kPa tire pressure in winter is not too high. Generally, the normal tire pressure for small cars is 250 kPa, which is sufficient for regular use. Considering thermal expansion and contraction, it's acceptable to slightly increase the pressure to 260 kPa in winter. Tire pressure refers to the air pressure inside the tires, essentially the 'blood pressure' of a car. It plays a crucial role in the vehicle's performance and power. Tire pressure is the lifeline of tires - both excessively high and low pressures can shorten tire lifespan. Low pressure increases tire body deformation, leading to sidewall cracks and flexing movements, causing excessive heat generation, rubber aging, fabric layer fatigue, and cord breakage. It also enlarges the tire's contact area, accelerating shoulder wear. Conversely, high pressure overextends tire cords, reduces elasticity, increases driving load, and may cause internal cracks or blowouts upon impact. Additionally, high pressure accelerates tread wear and reduces puncture resistance.
I've been driving for years and have always researched tire pressure. Inflating to 260 kPa in winter is indeed slightly high, as cold causes air to contract. You might think higher pressure compensates for temperature drops, but vehicles actually come with manufacturer-recommended values, usually posted on the door frame, typically between 220 to 240 kPa. I recommend checking when the tires are cold - excessive pressure reduces traction, especially on snowy or wet surfaces where skidding becomes likely, compromising braking performance. I've also observed that overinflation causes faster center tread wear, shortening tire lifespan long-term. If unsure, use a reliable pump to adjust or visit a dealership for professional measurement - never rely on guesswork. Remember, safety comes first, and regular checks prevent many issues.
