Understanding Tire Size and Specifications

Updated: Feb 23

Tires are easily one of the most important components to our safety while driving. We rely on them for turning, braking, accelerating, road gripping during wet or dry conditions, and overall responsiveness as the link between our vehicle's suspension and the road. However, many drivers often overlook the importance of their tires and/or don't fully understand the various tire specifications and options.

It is important to understand what size, load capacity, speed rating, and tire type is best for your vehicle. Choosing an improper tire can result in minor consequences, such as inaccurate speedometer readings, to major problems with steering, braking, and handling.

Many consumers begin their tire purchase by looking to the "code" on the sidewall of each tire to determine the size needed. The manufacturer-recommended tire specification code can also be found in the owner's manual for your vehicle or on the vehicle placard (most commonly located on the side of the driver's door, the glove box door, or the fuel door). When doing this you may see a series of numbers and some letters such as in the image below:

Tire specifications and codes and what they mean

It is important that drivers understand what their "tire code" actually means and why it's critical to choose the appropriate tire to fit the vehicle.
