What should I do if there are cracks along the sidewall of the tire?

Tire sidewall cracks, if relatively minor, may still allow for city driving, but high-speed or long-distance travel should be avoided. If the cracks deepen, the tire should no longer be used and must be replaced immediately. At this stage, the tire has undergone significant aging, and the sidewall is particularly vulnerable. Continued use may lead to air leakage or even a blowout, posing serious safety risks. Here are some additional details: 1. Tire lifespan: Generally, tires have a service life of 3-5 years. Around the 3-year mark, aging begins to occur, with fine cracks appearing on the sidewalls or tread. Over time, these cracks will gradually deepen. Beyond 5 years, tires are usually severely aged and should no longer be used—prompt replacement is necessary. 2. Methods to delay tire aging: (1) Try to park in shaded areas to prevent prolonged exposure to sunlight; (2) Avoid contact with corrosive substances such as oil or chemicals, which can damage the tire; (3) Consider using tire care products like tire glaze or tire wax to slow down the aging process; (4) Never overload the vehicle, as excessive weight can overstress the tire sidewalls; (5) After 3 years of use, regularly inspect the tire's condition.
As a veteran driver with over 20 years of experience, I've seen my share of tire issues. Sidewall cracks along the tread lines are no trivial matter—they indicate internal structural damage, much like a ruptured blood vessel. Pull over immediately and don't push your luck. If the crack is deep or exposes the inner cord layers, that tire must be replaced without delay. Don't hesitate to use the spare tire, and when changing it, ensure the jack is positioned at the vehicle's designated lift points. Afterwards, investigate the root cause—whether it's frequent rough-road driving or irregular tire pressure. I recommend making monthly tire inspections a habit, checking sidewalls for cracks or bulges. Replace when necessary—safety always trumps cost savings.
Having worked in a repair shop for over a decade, I've encountered many car owners bringing in tires with cracks. Sidewall cracks along the lines are generally irreparable because this is the weakest part of the tire. It's advised to stop driving immediately as high-speed conditions can easily lead to a blowout. When changing to a spare tire yourself, ensure safety by finding a flat surface and engaging the handbrake. Don't throw away the old tire; it's best to take it to a professional shop to assess the extent of the damage. Daily care should include avoiding prolonged exposure to sunlight and driving over speed bumps too harshly, as these can accelerate aging. Typically, tires have a lifespan of about 5 years, after which they should be replaced regardless of their apparent condition.
I just dealt with this situation last week. While driving back to my hometown, I noticed a thin crack on the sidewall of my tire. Initially, I didn't pay much attention to it, but later I came across an educational video that explained how dangerous such damage can be. I immediately went to a repair shop for an inspection, and the mechanic told me that this type of damage required a tire replacement. When getting the new tire, I specifically opted for a run-flat tire and also had a four-wheel alignment done. I'd advise new drivers to regularly check their tire conditions and ask the mechanic to take a look during car washes. Try to avoid scraping the curb when parking and slow down when going over potholes—these habits can help protect the tire sidewalls. Remember, tires are the only part of the car that makes contact with the road, so any issues with them are no joke.
