Your vehicle's tires are responsible for the grip and handling of the road while you drive. Proper tire maintenance provides safer driving as well better fuel efficiency. But how do you know when you need to get new tires? Here are some signs that it's time to switch out your vehicle's tires.    

Check the tread

The tread of a tire allows water and snow to flow through the grooves so the tires have better traction on the road. If the tread on a tire wears down too far, the slippery substances only have one place to go, underneath the tire, taking away your vehicle's grip on the road.   

To check the status of the tread on your tires, take the penny test. Insert a penny into the groove of a tire with Lincoln's head down. If you can't see the top of Lincoln's head, there's still some life left in your tire tread. But if the top of his head is visible, it's time to purchase new tires.   

When purchasing new tires, it's best to buy all four at once instead of one at a time. Maintaining the same size, brand, and tread allows for even wear; even little differences can cause extra wear and potential damage to important vehicle systems.    

Look for signs of wear

You can see if your tires are wearing evenly by checking the wear patterns. Underinflation causes shoulder (outer) wear and overinflation causes center wear. Misalignment of your vehicle's wheels can also cause uneven wear. If you notice signs of uneven wear on your car's tires, it's time to take it in for service.    

Watch out for cracks and blisters

If cracks become visible on the sidewall of the tire, it means it's starting to develop a leak. Bulges or blisters on the outer wall means the tire is weakening, which can lead to blowouts. If you see either, it's time to replace the tire.

Feel for vibration

Every vehicle has driving vibration, but too much shaking is a signal for problems. If a wheel is out-of-balance or misaligned, it can not only wear down the tire but also damage the suspension, brakes, or axle. Have your vehicle inspected as soon as you feel intense shaking.
