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

[ElizabethLynn]

A tire pressure of 3.0 is unlikely to cause a blowout on the highway, but this value is not normal. For safety reasons, it is recommended to reduce the tire pressure to the normal range before driving on the highway. The normal tire pressure range for most cars is between 2.3 and 2.5. Strictly speaking, tire pressure refers to the air pressure inside the tire. A tire pressure of 3.0 is significantly higher than the normal range. The reason it won't cause a blowout is that manufacturers generally recommend tire pressures with a 30% safety margin, and the maximum pressure a tire can withstand is as high as 3.5 to 4.2 MPa, meaning the tire's capacity is higher than the actual pressure.
