How to Check if a Tire is Underinflated?
2 Answers
Methods to determine if a tire is underinflated: 1. Visually inspect all four tires to see if any appear noticeably flat. 2. Use a tire pressure measurement device, such as a handheld tire pressure monitor or an onboard tire pressure display, to accurately measure the tire pressure. 3. Install a tire pressure monitoring system for real-time monitoring of tire pressure. Effects of underinflation: 1. Damage to the tire sidewall and inner edge: Damage to the tire sidewall or inner edge can cause slow leaks and significantly increase the risk of a blowout. 2. Foreign objects puncturing the tire: Nails and screws are common culprits that can puncture the tire, leading to slow leaks. If left unremoved, they can worsen the damage. 3. Deformation of the wheel rim flange: If the wheel rim flange is deformed due to impact, it can compromise the seal between the rim and the tire, resulting in slow leaks.
I've been driving for over 30 years and have developed a habit for checking tire pressure. Every morning before starting the car, I walk around it to inspect each tire's appearance. If a tire looks noticeably flat, especially the part touching the ground, it's most likely underinflated. I give it a kick to test the feel – a healthy tire will have some elastic rebound, while a soft one indicates low pressure. Heavy steering or sudden increase in fuel consumption while driving should also raise alarms. Underinflated tires not only waste fuel but also increase the risk of blowouts, so I use a tire pressure gauge weekly to check the exact pressure, keeping it at the standard value marked on the door frame. Developing this simple habit ensures peace of mind, safety, and extends tire life.
