How to Diagnose Tire Wear & Chop Patterns

Introduction

You can learn a lot about your car just by studying its tires. Tire symptoms can be interpreted and explained. Different car issues cause different tire wear patterns. Before you can fix your car’s problem, you need to know what to look for on your tires. After you figure out your car’s issue, see if you can repair the problem yourself. If not, take your car to a professional mechanic so that you can return to driving your car as soon as possible.

Difficulty: Easy

Instructions

Step 1

Inspect your tires. Look for signs of scallops or undulating cups on the outer edges of the tires. This can signal that a suspension part in your car is bent or worn out.

Step 2

Feel the surface of the tire. Check if the ridges have both a smooth edge and a sharp edge. This is called “feathering.” This can signify that your car has a toe-in problem.

Step 3

Check if the second rings of the car’s radial tires are more worn out than the other rings. This is called second-rib wear. This issue could mean that your tires are too large and therefore do not fit your wheels properly.

Step 4

Keep an eye out for one-sided wear on your tires. This problem can tell you to have the car’s wheel alignment adjusted.

Step 5

Fill your tires to the manufacturer-recommended air pressure level. Tires that are not filled properly can wear out and cause dangers for you and your car.

Tip

Have your car looked at by a mechanic if you are still unsure what is wrong with your car.
