Tires with minor cracks do not need to be replaced. It is recommended to replace tires every 5 to 6 years, or approximately every 80,000 kilometers based on mileage. The typical lifespan of a tire is five years, and small cracks may appear after about three years of use. If the cracks are minor and located on the tread of the tire, they are considered normal signs of aging, cracking, or wear and do not require replacement, but regular inspections are still necessary. However, if cracks appear on the sidewall of the tire, it is important to have it checked at a service center promptly and replaced if necessary, as the sidewall is the most vulnerable part of the tire and continued driving may lead to a blowout. Additionally, if the cracks are too long or deep, reaching the standard tread depth of 1.6 millimeters, replacement is also required.

I've experienced several tire issues before and believe that if cracks appear on tires, they should be taken seriously and addressed promptly. Cracks may be caused by tire aging, prolonged exposure to sunlight, or overloading, which can easily lead to the danger of a blowout, especially at high speeds. Safety first—don't take small cracks lightly. It's advisable to visit a professional auto repair shop as soon as possible for an inspection. They can use tools to measure the depth and location of the cracks. Generally, cracks on the sidewall are more dangerous than those on the tread. If the crack exceeds one millimeter in depth, the tire should be replaced. Tires are the only part of the vehicle in contact with the ground, and ensuring their good condition is a responsibility to life. Regular maintenance, such as monthly checks on tire pressure and wear, can prevent such issues and extend tire life. Remember, there are no small matters when it comes to driving safety—negligence can lead to lifelong regret.

From a budget perspective, replacing tires with cracks might be a cost-effective choice. A new tire costs some money, but ignoring cracks could lead to higher expenses like towing fees and repair costs after a blowout, or even accidents causing personal injury or property damage. In the long run, maintaining healthy tires improves fuel efficiency, saving both money and hassle. I always like to calculate costs, believing preventive spending is better than regret afterward. Of course, not replacing them immediately is also an option—minor cracks can be observed for a few days to see if they worsen. Consult a technician to assess the severity of the cracks: if they are only on the surface and not deep, replacement can be delayed; but if they are in critical areas like the sidewall or appear frequently, replace them without hesitation. Don’t skimp by using old tires—investing in safety is always worth it.

Whether tire cracks require replacement depends on the specific situation. Different types of cracks pose varying risks: minor tread cracks are often surface aging and can be temporarily ignored; sidewall cracks are more dangerous due to bearing greater pressure. Location and depth also matter—use a magnifying glass or gently touch with fingers to assess. If cracks exceed 1mm in depth or extend into grooves, reduced traction necessitates immediate replacement. Regular parking should avoid prolonged sun exposure to slow aging. Professional inspection is simple—repair shops can determine with a tire pressure gauge. Safe driving revolves around attention to detail, as small oversights can lead to major accidents.

During daily driving, I've developed a habit of checking tire conditions including cracks every week. Be cautious when cracks appear: they may result from dry climates or overloading causing rubber embrittlement. Monitor small, shallow cracks for changes; take action if width increases or shows an expanding trend. Don't delay, prevention is better than cure. Regular maintenance like tire rotation and balancing is recommended to extend service life. Also maintain proper tire pressure to reduce crack formation. As a meticulous person, I believe it's the owner's responsibility to maintain their tools well - small investments ensure smooth driving.
