Tire profile is the numerical representation of a tire’s dimensions and construction. Some call it tire size or tire specification. C’mon Alex, speak in English!

Simply put, tire profile is the height of your tire’s sidewall, measured as a percentage of the tire’s width. You need to know this number, especially when your tires need replacement.

But how do you know your tire profile? It’s simple!

Look at your tire’s sidewall


In today’s tire development, the tire profile is represented by a series of numbers and letters. In the US, it’s typically in the format of three numbers followed by a forward slash (“/”) and two additional numbers.

The second number after the slash mark represents the tire profile. For example, a tire with the size 225/60 R16 has a profile of 60%.

Let’s get a little deeper into the details, shall we? Here’s what each component of the profile represents:

  • Tire Width: The first number represents the tire’s width in millimeters. In the example above, 225 indicates that the tire width is 225 millimeters.
  • Aspect Ratio: The second number represents the aspect ratio or profile of the tire. It is expressed as a percentage of the tire’s height to its width. In the example above, 55 means that the tire’s height is 60% of its width.
  • Radial Construction: The letter “R” denotes the tire has a radial construction. Most modern tires have radial construction, so “R” is commonly seen.
  • Wheel Diameter: The last number indicates the diameter of the wheel or rim in inches. In the example above, 16 signifies that the tire is designed to fit a 16-inch wheel.

Alternative ways to know your tire profile


Sometimes the marking on the tire’s profile may be hidden or unclear. In that case, you can:

  • Check your vehicle owner’s manual. The tire profile is usually listed in the owner’s manual. That’s along with other tire information, such as the tire size, load index, and speed rating.
  • Look at your tire information sticker. This is usually located on the driver’s side door jamb or in the glove box door. You can find the tire profile and other tire information on the sticker.

If none of these help, then you should check with your local tire dealer.


Important Facts About Car Tires

Two Car tires

Tire profile plays a crucial role in determining the tire’s performance characteristics. This includes handling, ride comfort, traction, and fuel efficiency. But did you know…

  • A higher tire profile means a taller sidewall. This can provide a more comfortable ride but also reduce handling performance.
  • A lower tire profile means a shorter sidewall. This can improve handling performance, but it can also reduce ride comfort.
  • The tire profile is not the only factor that affects ride comfort and handling performance. Other factors, such as the tire tread design and the tire compound, also play a role.

Ultimately, the best tire profile for you will depend on your individual driving style and preferences. 

If you value comfort, go for tires with a higher profile. But if you value handling performance, you should choose low-profile tires. 


Recent Development in Car Tires


In the past, tires had a higher profile, which provided a more comfortable ride. However, as vehicles have become more performance-oriented, tire profiles have become lower to improve handling performance.

Recent developments in tire technology have made it possible to create tires with a lower profile without sacrificing ride comfort. These tires use new materials and construction techniques that allow them to be both lightweight and strong.

Some notable developments include:

  • Run-flat tires – designed to allow a vehicle to continue driving even if one or more tires are flat. Run-flat tires have a reinforced sidewall to support the vehicle’s weight for a short distance.
  • Self-sealing tires – have a layer of sealant that can automatically seal small punctures in the tire. This allows the tire to continue deflating slowly rather than rapidly.
  • Smart tires – equipped with sensors that can monitor the tire’s condition and provide the driver with information about the tire’s pressure, temperature, and wear.
  • All-Season and All-Weather Tires – designed to provide reliable performance in a variety of weather conditions. They offer a balance between wet and dry traction, as well as moderate snow and ice capabilities.

These are just a few of the recent developments in tire development. As technology advances, we can expect to see even more innovative tire designs in the future.



What is tire profile?

It is the height of a tire’s sidewall, measured as a percentage of the tire’s width.

How do I find my tire profile?

Just look at your tire sidewall or in your vehicle owner’s manual.

What is the difference between a high tire profile and a low tire profile?

A high tire profile has a taller sidewall, while a low tire profile has a shorter sidewall.

How does tire profile affect handling and ride comfort?

A high profile provides a more comfortable ride but can reduce handling performance. On the other hand, a low profile improves handling performance but can reduce ride comfort.

What are the most popular tire profiles?

The most popular tire profiles typically range from 55% to 70%.

What are the pros and cons of high and low tire profiles?

High tire profiles offer a more comfortable ride but can reduce handling performance and fuel efficiency. Low tire profiles improve handling performance and fuel efficiency but can reduce ride comfort.

How do I choose the right tire profile for my vehicle?

The best tire profile for your vehicle will depend on your individual needs and preferences. If you value ride comfort, choose a tire with a higher profile. If you value handling performance, go for one with a lower tire profile.
