Driving with a bubble in your tire can be dangerous as it can lead to a blowout. A blowout occurs when the tire bursts and can cause you to lose control of your vehicle. If you see a bubble in your tire, it is important to get it repaired as soon as possible.
There are a few different causes of tire bubbles. One common cause is hitting a pothole or other object that damages the tire. Another cause is overinflation, which can cause the tire to bulge and form a bubble. Underinflation can also cause a tire to bubble, as the tire will not be able to support the weight of the vehicle and will bulge out.
