What does Tire Anomaly 1.9 Mean?
2 Answers
Tire anomaly 1.9 indicates low tire pressure. It means the tire pressure monitoring system has detected low pressure in one or more tires. In this situation, you should slow down and brake gently to stop safely, avoid sharp turns, and correct the tire pressure when the tires are cold. Below are the hazards of both overinflated and underinflated tires: Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; Causes 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; Hazards of underinflated tires: Increased friction with the road surface, leading to higher fuel consumption; Creates steering difficulties and deviation, compromising driving safety; Increases movement in various tire parts, causing abnormal heat due to excessive rolling; Weakens cord and rubber functions, leading to delamination or cord breakage, and causes excessive friction with the rim resulting in bead damage and abnormal wear.
I've been driving for over a decade and occasionally encounter the 'Tire Abnormal 1.9' warning, which honestly gets quite annoying. The 1.9 refers to the tire pressure value in bar, and such a low number indicates insufficient pressure—probably around 1.9 bar. Normal tire pressure typically ranges between 2.0 and 2.5 bar, depending on the vehicle model. Low pressure leads to faster tire wear, increased fuel consumption, heavier steering, and unstable handling during turns. Once, during a long trip, I had a flat tire midway because of this issue and had to switch to the spare. I recommend always carrying a portable pressure gauge and checking the tires when refueling. If the warning light stays on constantly, it might mean a nail puncture or a leaking valve core—don’t ignore it and get it fixed promptly. Safe driving starts with attention to detail. Regular checks can save a lot of hassle.
