Importance Of Choosing The Correct Tire Size

Selecting the right tire size for your vehicle is crucial. Getting the wrong size can negatively impact your car’s performance, including handling, fuel efficiency, and even braking. Using the wrong tire size can also be dangerous and increase the risk of accidents.

Thus, it’s essential to ensure you’re fitting your vehicle’s correct tire size.

How To Read Tire Size Markings

As we mentioned earlier, understanding tire size markings is essential to choose the correct size for your vehicle. Here’s how to read the markings:

  • Look for the numbers on the sidewall of your tire.
  • The first number you see is the tread width in millimeters.
  • The second number is the aspect ratio, which represents the height of the sidewall as a percentage of the tread width.
  • The letter ‘r’ comes next, representing the tire type, which is radial for most vehicles.
  • The final number is the diameter of the wheel in inches.

By understanding tire sizing, you can confidently choose the correct tire size for your vehicle, improving overall performance and ensuring your safety on the road.
