Do Tires Need to Be Replaced if They Have Cracks?

[MacAaron]

If there are minor cracks on car tires, determine whether they need replacement based on the following criteria: 1. Outer edge wear: If significant wear is observed on the outer edge of the tire when viewed in the direction of travel, it indicates the tire is frequently underinflated (insufficient pressure). 2. Convex and wavy wear: If the tread shows convex wear on both sides and wavy wear around the circumference, it suggests severe wear in components such as shock absorbers, bearings, or ball joints. 3. Even surface wear: If the wear has reached the standard tread depth (1.6 mm for tires narrower than 1.75 mm, or 2 mm for wider tires), replacement is necessary. 4. Inner tire wear: If the inner side of the tire is worn and the outer edges appear jagged.

Should you replace tires with cracks? This is really worth discussing. As someone who frequently repairs cars, I've seen many cases: some people think small cracks are no big deal, only to regret it when the tire blows out. There are several types of cracks: small fine cracks on the tread may just be surface aging and not a major issue; sidewall cracks are the most dangerous—that area bears a lot of pressure, and once a large split occurs, the risk of a blowout at high speeds is extremely high. Also, consider the tire's age—tires older than six years have hardened rubber, and any cracks mean they should be replaced. Otherwise, you might suddenly run into trouble on a long drive, and the repair costs could far exceed the price of new tires. I’ve experienced this myself—a sidewall split on the highway nearly caused me to lose control. My advice: use a coin to test the depth. If you can see the top of the coin’s engraving when inserted, it’s time to act fast. Don’t skimp on small expenses only to suffer bigger losses—safety comes first. Visit a reliable shop for inspection or replacement. Also, pay attention to regular tire maintenance to extend their lifespan.

When there are cracks in the tires, I have to weigh the financial costs: a new set of tires might cost a few hundred dollars, but if the cracks are severe and lead to a blowout, the combined cost of repairs and towing can be even more alarming. In daily driving, I've learned my lesson: initially ignoring small cracks only to see them slowly expand on the sidewall, eventually causing a breakdown on the road and costing me double. Cracks aren't absolute—shallow ones on the tread can be monitored while driving, but deep cracks or those on the sidewalls shouldn't be ignored. The age of the tire is also crucial; generally, after four or five years of use, tires start to degrade, making cracks more likely to worsen. I'd recommend checking them yourself first: feel the depth of the cracks with your hand or have them measured with professional equipment at a shop. The money saved might not be worth the risk, especially for those who frequently drive on highways—safety is the best investment. Regularly replacing tires can reduce unexpected expenses, making it more cost-effective in the long run. Developing a habit of checking tire pressure and appearance monthly is better than dealing with the consequences—prevention is better than cure.

Should tires with cracks be replaced? Not necessarily, but it depends on the situation. Simply put: small cracks aren't a big deal, but if the cracks are deep, especially on the sidewall, they could lead to a blowout. I've driven for many years and experienced a sidewall crack: it wasn't obvious at first, but the tire suddenly lost pressure at high speed—luckily, I stopped quickly without incident. Aging tires, especially those over six years old, are prone to problems. It's recommended to regularly inspect them yourself: look for dark cracks with your eyes, or take them to a repair shop for evaluation. Safety first—don't take risks.
