Is a tire pressure of 245 normal?
2 Answers
A tire pressure of 245 KPA is quite normal, equivalent to 2.4 BAR. The normal range for tire pressure is between 230 KPA and 250 KPA. Driving with low tire pressure can cause severe tire wear, and in serious cases, may lead to a tire blowout. Hazards of excessive tire pressure: Reduced friction and adhesion of the tire, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern of the tire, shortening its lifespan; Increases body vibration, indirectly affecting the lifespan of other components; Causes excessive stretching and deformation of the tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, the tire is more prone to punctures, and impacts can cause internal cracks and blowouts. Methods for addressing insufficient tire pressure: If no damage is visible, simply inflate the tire to the normal pressure and reset the tire pressure system; If a puncture is found during inspection, drive to a tire shop promptly for repair and then reinflate the tire; If the tire pressure warning appears again some time after inflation but there is no puncture, it may be due to air leakage caused by a deformed wheel rim. It is recommended to check the wheel rim and replace it if necessary.
I often check tire pressure myself. Based on over a decade of driving experience, the number 245 is generally within the normal range for most sedans if it's measured in kPa. Standard tire pressure typically falls between 200 to 250 kPa, but the key is to refer to your vehicle's manual or the label on the driver's door pillar, which shows the manufacturer's recommended value. If the recommendation is around 240 or 250, then 245 is perfectly fine; but if it's 220, then it's slightly high. Overinflated tires can lead to faster wear in the center, reduced comfort, potentially longer braking distances, and a bumpier ride on rough roads. Conversely, underinflation increases fuel consumption and the risk of a blowout. So, I recommend checking the manual first to ensure the numbers match before driving, especially during seasonal weather changes. This number isn't universal—each car is different. Safety first is always the best approach. Keeping an electronic tire pressure gauge in the car for regular checks is very convenient.
