One common symptom of tire problems is bald spots on the tires. This can be caused by a number of things, including improper inflation, overloading, or even just wear and tear. Another common symptom is a bulge in the sidewall of the tire. This can be caused by a number of things as well, but it's often indicative of internal damage to the tire that could lead to a blowout. Finally, another common symptom of tire problems is vibration when driving. This can be caused by many different things, but it's often an indication that the tires are out of balance or that there's something lodged in between the treads. If you're experiencing any of these symptoms, it's important to have your tires checked out by a professional as soon as possible to avoid further damage or even a potential accident.
