It’s time to purchase new tires if the tread on your current set has worn down and no longer offers effective traction. When you head to a shop to buy new tires, it’s essential to understand sizing to purchase the right ones. Selecting the wrong size could lead to dangerous consequences. Below is a guide to help get you started.

How to Find the Proper Tires For Your Car

Establish What Size You Need

Many car models detail what tire size is needed on the inside frame of the driver’s door. Look for a small tire and loading information sticker denoting the size for the front and rear tires and how much air to pump them with. The vehicle manual should also highlight these specifics. 

How to Read Tire Sizes

If this information is not available, check the tire sidewalls. There, you should spot a series of letters and numbers beginning with a P to indicate that the vehicle is for passenger use or LT for light trucks. The three-digit number next to this indicator denotes the tire width, followed by a backslash. The next two numbers refer to the ratio of the tire’s height to its width. For example, a 55 means the width is 55% of the height. Then, you’ll find the construction type, often with a letter R stating that the tire was layered vertically. 

The next numbers show the wheel size that matches with the new tires. Then, you’ll see the maximum load the vehicle can support followed by a speed rating sharing the fastest the tire could go. It’s important to note that this number is not a recommended speed, as it’s often several times the legal speed limit.

Consequences of Purchasing the Wrong Size Tires

Installing the wrong tires can have serious consequences for those inside the vehicle and around it. If the tires are too large, the speedometer may incorrectly say you’re driving slower than you are, and too-short tires will potentially make it appear that you’re driving faster than you really are. You may notice the car pulling in one direction, reduced braking sensitivity, and issues maintaining traction in wet weather. All tires should be the same size, otherwise you’ll likely experience instability and stress the transmission, which can cause costly damage.
