What will happen if driving with tire pressure at 1.8?
2 Answers
Driving with tire pressure at 1.8 may lead to the following situations: 1. The steering wheel becomes heavier and the vehicle may deviate from its path; 2. Increased fuel consumption due to greater friction between the tires and the ground, resulting in higher running resistance; 3. Accelerated tire wear, shortening the lifespan of the tires. When the tire pressure is at 1.8, high-speed driving should be avoided as it significantly increases the risk of a tire blowout. Under normal circumstances, the front tire pressure should be 2.2 to 2.3 bar when unloaded and 2.4 to 2.5 bar when fully loaded; the rear tire pressure should be 2.4 to 2.5 bar when unloaded and 2.6 to 2.8 bar when fully loaded. Due to differences in vehicle size and weight, the normal range of tire pressure may vary slightly. It is advisable to adjust according to the manufacturer's recommended standard tire pressure values.
A few days ago I drove on the highway with tire pressure at just 1.8 bar, and honestly the car felt extremely unstable. The steering wheel was light and floaty, and when taking turns the car felt like it was drifting. After driving dozens of kilometers, the outer edges of the tires were severely worn, forcing me to spend money on new tires. What's scarier is that the braking distance increased, almost causing a rear-end collision. Experts say such low pressure makes tires rub against the road more, increasing fuel consumption by 10%, and the higher tire temperature raises the risk of blowouts - especially dangerous at highway speeds. I've bought a portable inflator and recommend everyone check tire pressure regularly, maintaining it at the manufacturer-recommended level (usually 2.2-2.5 bar) for safe and worry-free driving.
