Can You Still Drive with Low Tire Pressure?
2 Answers
You should not continue driving with insufficient tire pressure as it poses safety hazards. Low pressure increases tire deformation, leading to cracks on the sidewalls and excessive flexing, which generates heat, accelerates rubber aging, causes fatigue in the cord layers, and may break the cords. It also enlarges the tire's contact area with the road, speeding up shoulder wear. Conversely, overinflation overextends the tire cords, reducing elasticity and increasing the load on the tire during driving, which can cause internal cracks or blowouts upon impact. Overinflation also accelerates tread wear and reduces resistance to punctures. Tires are round, elastic rubber products mounted on metal rims, designed to support the vehicle's weight, absorb shocks, maintain contact with the road, and ensure driving performance.
The other night after work, it was dark and the roads were crowded. As I was driving my old Ford home, I noticed the steering wheel felt unusually heavy, and after a while, the car seemed to float. I immediately thought the tire pressure was low. I’ve had this happen before when I stubbornly drove to a repair shop, only to hear a loud bang—a flat tire—shortly after. Luckily, I wasn’t on the highway, so no accident occurred.
When tire pressure is low, the most obvious issue is a spike in fuel consumption—about 10% more in gas costs. Tire wear also accelerates because the increased contact area causes the rubber to wear down faster against the road. Handling becomes poor, too, risking skids or accidents during sharp turns. If you absolutely must drive, go slowly—no more than 20 mph—to the nearest gas station or repair shop, and check for nails or other punctures.
Remember: safety first. If the tire pressure is below the recommended level, don’t push your luck. Otherwise, repair costs will far exceed the price of a simple refill.
