Spare tire

Okay kiddo, imagine you are on a long trip with your family in a car. Sometimes, the car can get a flat tire which means the tire is no longer good and can't keep the car moving. This is not a good thing, right?

So, car makers include a spare tire in the trunk of the car. It looks different than the other tires and it's usually smaller. If a tire becomes flat, your grown-ups or someone who knows how to change tires will take off the bad one and put on the spare tire. This will let the car keep moving while they get the old tire fixed or replaced.

It's important to remember that the spare tire is not as good as the other tires, and it's only meant to be a temporary fix. That's why it's always important to get the original tire fixed or replaced as soon as possible so it doesn't happen again.
