Learning how to identify when you need to purchase new tires can be a daunting task. However, we hope to make that process a little easier. First, you must understand that it is important to check your tires at least once a month. The reason being is that you want to ensure that your tires are safe to drive on, or determine if they are in need of service or replacement. If you find that your tire is flat from a puncture from a nail or other road hazard, then there is still a chance the tires can be repaired. Your chances for repair or highest when:

  1. You have not driven on the damaged tire while it is flat.
  2. Any damage appears on the tread part of the tire (the area that comes in contact with the road)
  3. Finally, if the puncture is less than a ¼ inch. If you feel your tire exhibits any of these conditions, contact your local auto service center immediately. They can tell you if your tire can be repaired or needs to be replaced. Remember, worn tires are not only unsafe to drive on; they are against the law. Legally the minimum tire tread depth is 2/32 inch. When the road is wet, 4/32 or less tread can mean a high risk of significant loss in wet traction. In other words, hydroplaning, which can put both the passenger and you at risk.

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

1. Penny Test To test to see if your tread has been worn out, place a penny into the most shallow tread groove with Lincoln’s head facing down. If the top of his head is still visible, then the tire needs to be replaced.

2. Look for the wear bars The wear bars are the narrow bands that appear in the grooves across the tread of the tire. When the wear bars are even with the depth of the tread, that means that only 2/32-inch of tread is remaining. If you are able to see the wear bars, then you tire needs to be replaced.

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
