Can You Continue Driving with Tire Pressure at 170?
2 Answers
Tire pressure at 170 should not be continued for driving. Low pressure increases tire deformation, leading to cracks on the tire sidewalls and reduced elasticity, which increases the load on the vehicle while driving. In case of impact, it may cause internal cracks and blowouts. The hazards of low tire pressure are as follows: 1. Increased friction coefficient with the road surface, leading to higher fuel consumption. 2. Causes heavy steering and potential deviation, which are unfavorable for driving safety. 3. Increases the movement of various parts of the tire, causing abnormal heating due to excessive rolling. 4. Reduces the functionality of the cord and rubber, leading to delamination or cord breakage, and excessive friction with the rim, causing damage to the bead area and abnormal wear. 5. The friction between the tire and the ground increases exponentially, causing a sharp rise in tire temperature, softening of the tire, and a rapid decrease in strength. High-speed driving may result in a blowout. 6. Low tire pressure increases tire deformation, leading to cracks on the sidewalls and flexing movements, causing excessive heat, rubber aging, fatigue in the cord layers, cord breakage, and an increased contact area with the ground, accelerating shoulder wear.
A tire pressure of 170 is too low, and you absolutely must not continue driving for too long, otherwise the risks are significant. I remember once driving on the highway with low tire pressure, and the car shook violently—that’s when I realized the tire sidewalls were under excessive stress, making them prone to blowouts. Standard tire pressure usually ranges between 190 and 250, so 170 is far too low and can cause excessive tire wear and a sharp increase in fuel consumption. It’s best to find a safe spot to stop and check immediately, either using an air pump to inflate the tires or calling for roadside assistance. To avoid such trouble, make it a habit to check your tire pressure every two weeks—safety always comes first.
