Car tires tend to last for around four to six years, so if your tires are reaching the end of this lifespan, it’s wise to consider having them replaced. You should also consider new tires if you notice the following signs of premature tire wear and tear. Technicians at your local Cadillac dealership can inspect your tires and determine how much longer they’re likely to last.
Cracked Sidewalls
The sidewalls of tires are usually the first part to dry out and develop tiny cracks. This is a result of prolonged exposure to sunlight, water, and chemicals from the road. When these sidewall cracks begin to grow and spread noticeably, the tire may be losing its structural integrity and should be replaced soon.
Blistering Tire Rubber
Blisters and bubbles anywhere on the tire’s surface are signs of serious damage. Sometimes layers of rubber might slip loose, causing the blistering. A sharp blow from a pothole or curb might also have punctured the inner tubing layer, causing air to seep out and create the blister.
Tire Tread Chunking
Overheating can sometimes cause a tire’s treads to soften to the point where small chunks break off. Tire tread chunking often looks like rodents have been nibbling at the treads. A tire with tread chunking is no longer safe to drive upon.
Tire Tread Cupping
While driving, if you’re getting excessive vibrations from the road, check your tires for signs of cupping. Cupping is where parts of a tire’s treads have worn down into little ‘cups’ with regular spacing. This phenomenon is often caused by misaligned suspension or wheels. A tire with cupping usually has to go.
Gashes in the Rubber
Any serious damage to a tire’s sidewall can potentially cause tire failure. Deep cuts and gashes are the clearest kind of sidewall damage. It’s best never to drive on a tire with a gashed sidewall.
Embedded Objects
Nails, screws, and other metallic objects can become embedded in tire rubber. If the object is very small and penetrates the thick tread area, then the damage may be minimal. But deeper penetration or embedding in the sidewall could easily result in a puncture.
Exposed Tire Cords
If you ever see exposed cords or steel belting at the edge of your tire, you may have a camber or alignment issue. The tire should be replaced, and it’s also wise to have a technician diagnose and resolve the underlying problem.
