How Often Should Tires Be Inflated Normally?
2 Answers
There is no standard reference for this. Generally, it is recommended to inflate tires twice a year or check the tire pressure before driving on highways, including the spare tire. Car owners should regularly check the tire pressure and inflate when the pressure is insufficient. The standard tire pressure is usually around 2.2~2.6 bar. Air pressure is the lifeline of tires; both overinflation and underinflation can shorten the tire's lifespan. Below is relevant information: 1. Underinflation increases tire body deformation, leading to cracks on the tire side and flexing movements, which cause excessive heat, accelerate rubber aging, fatigue the cord layer, and break the cords. It also increases the tire's contact area with the ground, accelerating shoulder wear. 2. Overinflation causes excessive stretching deformation of the tire cords, reduces the tire body's elasticity, and increases the load on the car while driving. In case of impact, it may lead to internal cracks or bursts. Overinflation also accelerates tread wear and reduces puncture resistance.
I've been driving for years, and tire inflation is something you can't take lightly. Generally speaking, checking the pressure once a month is the safest approach, as tires naturally lose a bit of air over time and may fall below the recommended level. I prefer measuring the pressure three hours after the car has been parked, in the 'cold tire' state, as this gives the most accurate reading. The recommended pressure is usually listed on the door jamb, and it varies by vehicle model. If you frequently drive on highways or carry heavy loads, you might need to top up the air every two to three weeks. I've noticed that driving with underinflated tires increases fuel consumption by up to 10%, which really adds up over time. Plus, low pressure causes uneven tire wear, shortens tire life, and increases the risk of a blowout—safety first! Make it a habit to check on a set day each month—it saves both hassle and money.
