Will a tire pressure of 3.0 cause a blowout on the highway?

[ORafael]

A tire pressure of 3.0 will not cause a blowout on the highway. The reason it won't blow out is that the manufacturer's recommended tire pressure includes a 30% safety margin. Tires can withstand pressures as high as 3.5 to 4.2 bar, meaning their capacity exceeds actual requirements. The normal tire pressure range for cars is between 2.3 and 2.5 bar. For safety reasons, it is recommended to reduce the tire pressure to within the normal range before driving on the highway. A tire pressure of 3.0 on the highway can negatively impact tire lifespan and driving safety, potentially accelerating central tread wear, causing abnormal tire wear, shortening tire lifespan, and making the tires too hard, which could indirectly damage other vehicle components.
