Can tires with small cracks around the sidewall still be used?

Tires with small cracks around the sidewall indicate the beginning of aging. Whether they need to be replaced depends on the remaining tread depth. If the remaining tread is shallow, new tires should be replaced immediately. Below is relevant information about car tire replacement: Replacement time varies depending on circumstances: With good driving habits, tires generally need to be replaced every 3-5 years or after driving 60,000-80,000 kilometers. If driving conditions are harsh, such as frequently traveling on gravel roads or experiencing frequent traffic jams, sudden braking, or sharp turns, the replacement time will be shorter. Tire aging time: The main material of tires is rubber, which naturally ages over time. This primarily manifests as the tires hardening and the sidewalls becoming covered with small cracks. Natural aging typically occurs within 4-5 years. Tires should be replaced after 5 years to prevent the risk of blowouts. Observing tire wear: If the tires are severely worn, and the tread pattern is level with the wear indicators, the tires should be replaced. Otherwise, braking on wet or slippery roads will be more difficult, and the vehicle is prone to losing control. Driving on excessively rough roads may also increase the risk of blowouts.

Regarding the issue of small cracks on the sidewall of the tire, I must emphasize from a safety perspective that it is best not to continue using it. Those small cracks are a critical sign of tire aging, and the sidewall is the most vulnerable part of the tire. Once cracked, it can compromise the structural integrity of the entire tire. During high-speed driving, encountering potholes, or making sharp turns, these cracks may suddenly expand, leading to a blowout or loss of control, which is extremely dangerous. I have seen many cases where drivers ignored these small cracks, resulting in severe accidents due to loss of control on highways. The causes of such cracks are usually prolonged exposure to UV rays, natural rubber aging, or improper storage. I strongly recommend immediately discontinuing the use of this tire and having it inspected by a professional tire shop. If the crack depth exceeds 1 millimeter, replacement is mandatory. Even if the cracks appear superficial, it is advisable to replace the tire as a precaution. When parking, choose shaded areas to extend tire lifespan. Safety should always come first—don’t risk it to save money.

As someone who has driven for many years, I believe whether a tire with small cracks can still be used depends on the depth of the cracks. If it's just surface cracking and doesn't extend too deeply, it might hold up for a while, but you must carefully monitor any changes. Cracks on the sidewall are usually caused by rubber aging or frequent parking in direct sunlight. I'd recommend you try feeling the depth of the cracks: if it's just a thin layer, not exceeding a millimeter, driving short distances at low speeds might be acceptable for now, but definitely avoid long trips or high speeds. From a cost-effective and practical perspective, you can first monitor the speed of crack expansion—if it noticeably widens after a few months, you must replace it immediately. Additionally, check the tire's production date (usually a four-digit code on the sidewall). Tires older than five years are more prone to cracking and aging, so don't hesitate—replace them right away. Developing a habit of quickly checking the sidewall condition every time you wash your car can save you a lot of hassle.

Let's discuss the causes and impacts of small cracks and sidewall crazing on tires. This is often the result of prolonged exposure to sunlight, as UV rays make the rubber material brittle; or it could be due to natural aging from prolonged use without replacement. Once cracks appear on the sidewall, they compromise the tire's structural integrity since this area bears the brunt of vehicle weight and road impacts. Minor cracks may not cause immediate blowouts but can accelerate issues like unstable tire pressure, affecting braking distance and fuel efficiency. I recommend assessing the spread of cracks: if they're just fine surface lines without deepening, short-term use is possible but risks accumulate; if coverage is extensive or depth increases noticeably, immediate replacement is necessary. Regular tire maintenance, such as parking away from direct sunlight, can extend lifespan and prevent such issues.

I have a real-life experience to share. A friend of mine had small cracks resembling turtle shell patterns on the sidewall of his tire. He thought it was fine and kept driving, but two months later, the tire suddenly blew out on the highway, nearly causing an accident. So, such cracks should never be taken lightly—they are clear signs of tire aging, indicating reduced rubber strength and the potential inability to withstand pressure at any moment. My advice is, if you notice cracks, first take photos to track changes: if they spread or deepen quickly, immediate action is necessary. If possible, drive to a professional tire shop and have the technician measure the depth with tools to get expert advice. Safety comes first; don't risk major losses for minor savings, as the cost of replacing a tire is far lower than the cost of an accident. Make it a habit to inspect all tires for external damage every six months—prevention is key.

Regarding small cracks on tire sidewalls, my opinion is to address them as soon as possible to prevent further deterioration. Small cracks indicate rubber aging, especially in the vulnerable sidewall area, and continued use increases the risk of a blowout. The main causes are prolonged exposure to sunlight or improper storage, so parking in shaded areas can help slow crack propagation. If the cracks are only superficial and form a shallow ring, the tire might still be usable for a short period, but avoid highways and rough roads. I recommend prioritizing a professional inspection to assess the depth and extent of the cracks. Also, check the tire's manufacturing date—if it's over five years old, consider replacing it outright. For prevention, regularly clean and inspect the sidewalls, and promptly repair or replace any cracks to extend the lifespan of other tires. Safe driving is crucial—don’t let small issues escalate into major problems.
