Where to Position the Jack When Changing a Car Tire?
1 Answers
When changing a car tire, the jack should be positioned under the vehicle's chassis. Operate the jack steadily and rhythmically during lifting, and lower it slowly. If using multiple jacks simultaneously, ensure synchronized operation. After using the jack, conduct a thorough inspection to check hydraulic pressure and potential hazards, perform necessary maintenance, and store it in an appropriate location. Situations requiring tire replacement: 1. Check the tire wear indicators: All tire brands feature wear indicator marks in the tread grooves. When the tread depth wears down to the level of the raised indicator rubber, it's time to replace the tire. 2. Bulging appearance: A bulged tread indicates localized rubber deterioration or uneven pressure. Such tires are at risk of sudden blowouts, making continued driving highly dangerous, so immediate replacement is necessary.
