Knowing when to replace your tires is critical in maintaining safe vehicle operation.
Below are some common “Best Practices”

  1. NEVER drive on a flat tire!
    Doing so will damage the tire beyond repair and it must be replaced immediately.
  2. Driving on a tire that is underinflated or overinflated is equally destructive to the tire.
  3. Replace tires that are over 6 years of age
  4. Always check tire pressure before leaving for a road trip or vacation
  5. Visually inspect tires before driving.
  6. Check for any unusual tire wear as this could be a sign of an underlying issue with the tires or the vehicle.

Below are the two most common ways to check for worn tires:

1. The Penny Test
The “Penny Test” is one of the oldest tests to check for tire wear. Place a penny into the tire groove with Lincoln’s head facing down. The tire should be replaced if you can see the top of his head.

2. Check the tire wear bars.
The tire wear bars are cross bands that tie together the tire treads. If the tire wear bars are making contact with the road surface, it’s time to replace the tires.




Once you have determined that your tires are in need of replacement you can now figure out how many tires to replace. Most people replace tires in sets of 2 or 4. But it is possible for you to replace 1 tire (if you have a flat) or 3 tires as well.

When replacing 1 tire

You are going to want to find an exact match for the damaged or worn tire. That means you want to replace it with the exact brand, model, speed rating and load capacity. (Information about these items is in the next section) If you use a different tire than what was previously on there, you put your vehicle at risk for poor handling, pulling and instability.

When replacing 2 tires

You are going to want to replace with the same or better-quality tire. It is suggested that you buy two of the same tires when replacing. That way they should wear evenly and perform in line with one another. It is also suggested that you mount the new tires on the rear of the car (if rear wheel drive) or front of your car (if front wheel drive), and move the older tires to the front/rear of the car. This is because the newer tires have a deeper tread which helps with hydroplaning resistance so they can grip the road better than your older tires. You can then steer to compensate for the lower wet traction worn front tires to safely control your vehicle.

When replacing 3 tires

When replacing 3 tires, you will want to follow the same rules as replacing two tires. You will want to put the two newer tires in the back and move the older tire to the front. It is best to keep the rear tires the same and the front tires the same. So when replacing three, you want to make sure the two in the rear are the same tire, and that the new one up front is the same as the older tire that is currently on the vehicle. However, if there isn’t much tread life left on the one older tire, it would be best just to replace all four at that point.

When replacing 4 tires

At this point you have many different options. This is the best situation to be in because you can change the size and quality of your tires to suit your particular driving needs. To find the right tires for your vehicle click here
