Understanding Tire Size Notation

If you’re new to tire sizes, it can seem a bit confusing. Here’s a breakdown of what each part of the tire size means:

Choosing the right tire size is not just about aesthetics; it’s about performance and safety. Here are a few reasons why you should pay attention to tire size:

• Handling: The right size ensures optimal handling and steering response.
• Comfort: Properly sized tires contribute to a smoother ride.
