How To Identify W Speed Rated Tires

When it comes to choosing the right tires for your vehicle, knowing how to identify W speed rated tires is essential. This section will guide you through locating the speed rating on a tire sidewall and understanding the tire size and performance code.

Locating The Speed Rating On A Tire Sidewall

The speed rating is usually included in the tire size and performance code, which can be found on the tire’s sidewall. The code consists of a series of letters and numbers. For example, let’s consider the following code:225/50R17 94W.

In this example, the letter ‘W’ at the end of the code represents the speed rating. This tire is W speed rated and capable of handling speeds up to 168 mph.

Understanding Tire Size And Performance Code

To help you better understand the tire size and performance code, let’s break down the example mentioned earlier,225/50R17 94W:

  • 225: This number represents the tire width in millimeters.
  • 50: This number is the aspect ratio, which is the ratio of the tire’s height to its width (in this case, the tire’s height is 50% of its width).
  • R: This letter stands for radial, which indicates the tire’s construction type.
  • 17: This number represents the wheel diameter in inches (the tire is designed for 17-inch wheels).
  • 94: This number is the load index, which indicates the maximum weight the tire can support when properly inflated.
  • W: As mentioned earlier, this letter is the speed rating, indicating that this tire can handle speeds up to 168 mph.

Importance Of Matching Speed Ratings On All Four Tires

It’s crucial to have the same speed rating on all four tires of your vehicle. Mixing different speed-rated tires can lead to uneven handling and may compromise your vehicle’s safety and performance. Always consult your vehicle owner’s manual for the recommended speed rating and make sure all four tires have the same rating when you replace them.
