Does Changing a Tire Take Half an Hour?
2 Answers
Changing a tire takes about half an hour. Below are the detailed instructions for tire replacement: 1. Replacement duration varies by situation: For car owners with good driving habits, tires generally need to be replaced every 3-5 years or after driving 60,000-80,000 kilometers. If driving under harsh road conditions, such as frequently traveling on gravel roads or experiencing frequent traffic jams, sudden braking, or sharp turns, the replacement interval will be shorter. 2. Tire aging time: The main material of tires is rubber, which undergoes natural aging. This primarily manifests as the tire hardening and the sidewalls developing small cracks. Typically, natural aging occurs within 4-5 years. Tires should be replaced after 5 years of use to prevent the risk of blowouts. 3. Observe tire wear: If the tire is severely worn, and the tread pattern is level with the wear indicator, the tire needs to be replaced. Otherwise, braking on wet or slippery roads will be more difficult, and the vehicle is prone to losing control. Additionally, driving on excessively rough roads increases the risk of blowouts.
I've been repairing cars for at least ten years, and changing tires is second nature to me. With the right tools and if the tires aren't rusted shut, I can finish a car in 20 minutes. But in practice, there are plenty of issues—uneven roadside surfaces mean finding bricks to prop up the jack, rusty bolts on old cars require spraying loosening agent and waiting ten minutes, and numb hands in winter make it hard to remove them. The worst is dealing with aluminum alloy rims; you have to apply even force when tightening the bolts, or they might strip. I recommend beginners not to time themselves at first. Instead, practice a few times with an experienced driver to get familiar with the wrench angle and jack support points. Hitting the 30-minute mark is pretty good. Most importantly, safety comes first—never crawl under the car if it's not securely lifted.
