Can the Volkswagen Sagitar Check the Tire Pressure Reference Value?

[MacMaria]

Volkswagen Sagitar can check the tire pressure reference value, which can be found on the label inside the fuel tank cap. The standard tire pressure for Sagitar tires is 2.4-2.5bar, but it can fluctuate depending on specific conditions. In summer or winter, due to the principle of thermal expansion and contraction, tire pressure will increase in high temperatures and decrease in low temperatures. Therefore, summer tire pressure should be lower than winter tire pressure. Generally, it is recommended to set summer tire pressure at the lower limit of the standard tire pressure, while winter tire pressure should be appropriately increased by about 0.2bar based on the standard pressure. Hazards of excessive tire pressure: Tire friction and adhesion will decrease, affecting braking performance; It can cause steering wheel vibration and deviation, 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 vehicle during driving; Decreases puncture resistance, making it easier for sharp objects like nails or glass to penetrate the tire, leading to internal cracks or blowouts. Hazards of insufficient tire pressure: Increases friction with the road surface, leading to higher fuel consumption; Causes heavy steering and deviation, posing safety risks; Increases movement in various parts of the tire, leading to abnormal heat due to excessive rolling; Reduces the functionality of cords and rubber, causing delamination or cord breakage and excessive friction with the rim, damaging the tire bead and causing abnormal wear; Multiplies friction with the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to blowouts; Increases tire deformation, making the tire side prone to cracks and causing flexing movements that lead to overheating, rubber aging, cord fatigue, and breakage. It also increases the tire's contact area with the ground, accelerating shoulder wear.
