How do I know when it is time to get new tires?
assistant
The best way to tell if you need new tires is by checking the tread depth of your current tires. You can check this by using a penny or other flat object and pressing it firmly into the tire. If the imprint remains visible, then it's time to replace the tires. Additionally, you may want to look at the tire wear indicator on your car's dashboard; if this light comes on, it means that you should replace your tires soon.
