Can You Drive with 80 Tire Pressure?
2 Answers
Tire pressure of 80 cannot be driven. A tire pressure of 80 refers to the vehicle's tire pressure being 0.8 atmospheres, which is far below the normal tire pressure value. Immediate pressurization of the vehicle's tires is required. According to the international GBT2978-2008 standard, the recommended tire pressures for different tires are as follows: standard tires should be 2.4-2.5 bar; reinforced tires should be 2.8-2.9 bar; while the maximum pressure should not exceed 3.5 bar. The hazards of low tire pressure are as follows: increased friction coefficient with the road surface, leading to higher fuel consumption; causing the steering wheel to become heavy and prone to deviation, which are factors detrimental to driving safety; increased movement of various parts of the tire, leading to abnormal heating due to excessive rolling; reduced functionality of the cord and rubber, causing delamination or cord breakage, excessive friction with the rim leading to damage at the bead area, and abnormal wear; multiplied friction between the tire and the ground, causing a sharp rise in tire temperature, softening of the tire, and a sharp decrease in strength, etc.
A tire pressure of 80 is absolutely unsafe and way too high. Normal tire pressure typically ranges between 30 and 35, so check your car door label or manual. Exceeding 50 is extremely dangerous, and 80 is nearly three times the normal value, which overstretches the tire rubber and increases the risk of a blowout, especially at high speeds where rising temperatures make it even more likely. I remember a friend whose tire pressure was too high—suddenly, the tire burst on the road, causing the car to lose control and crash into the roadside. Luckily, no one was hurt. Handling is also affected, with longer braking distances and reduced maneuverability in turns. I recommend stopping immediately in a safe spot, using a tire pressure gauge to check and release air. If you don’t have the tools, call a tow truck or drive slowly to a repair shop. Never take the risk—safety first is the fundamental rule of driving.
