When changing car tires, attention should be paid to selecting the correct tire size, tire date, choosing the appropriate tire tread pattern, testing balance, etc. The specific details are as follows: Pay attention to selecting the correct tire size: The size of the car tire is marked on the side of the tire, consisting of three sets of numbers, such as 205/55/16. The first set of numbers represents the width of the tire in centimeters, and the middle set represents the percentage of the tire's width to the sidewall height. Pay attention to the tire date: The production date of the tire is also marked on the side of the tire. First, look for the letters "DOT," followed by a box containing four numbers, such as 1417, indicating that the tire was produced in the 14th week of 2017, and 2415 indicates the 24th week of 2015. When replacing tires, it is best not to choose tires older than two years, but there is no need to insist on the latest date; tires around one year old will not affect normal use. Pay attention to choosing the appropriate tire tread pattern: Tires of the same brand are also divided into different tread patterns. The tread pattern on the surface of car tires not only provides traction and drainage but also different tread designs can increase wear resistance and reduce noise. Pay attention to testing balance: After installing new tires or performing tire disassembly and assembly, it is necessary to test the balance. Tires mounted on rims usually do not distribute weight completely evenly. A balancing machine is used to test the balance of the tire and rim during movement, and balance weights are used at the unbalanced points to ensure smooth driving and avoid vibrations.
When changing tires, I pay special attention to safety. Don't start working right away—first park the car on a flat, hard surface, engage the handbrake, and shift into neutral. Never operate on a slope or soft ground. Place a warning triangle 50 meters behind the car to ensure safety for yourself and others. When using the jack, align it with the chassis support points and lift steadily. Don't rush to remove the bolts—loosen them slightly first, then slowly take off the old tire. Before installing the new tire, check that its size and specifications match the original. Don't cut corners by buying used or incompatible models. Tire pressure is crucial—adjust it to the standard value listed on the door label or manual. Overinflation risks blowouts, while underinflation wastes fuel and accelerates wear. After installation, always perform a balance test to avoid dangerous vibrations at high speeds. I also keep emergency tools handy and regularly check tread depth—replace tires if it's less than 1mm. Safety first—these small details prevent major issues.
