Where to Find Your Tire Size

Knowing where to find your tire size can save you time and hassle. You can find this information:

  • On the tire’s sidewall
  • Inside your vehicle’s door jamb
  • In the owner’s manual

If you need help deciphering these details or determining the best tire for your vehicle, Hale’s Automotive is ready to assist.

How to Read a Tire Size on Your Sidewall

On your tire’s sidewall, you’ll find a series of letters and numbers, such as P225/70R16. These characters provide essential information about your tire’s specifications. Let’s break down each part to understand what your tire needs and how it supports your vehicle.

Tire Type

The first letter indicates tire type:

  • “P” stands for P-Metric, designed for passenger vehicles like sedans, minivans, and crossovers.
  • “LT” designates a Light Truck tire, suited for trucks and SUVs that may carry heavier loads.

Tire Width

The three-digit number after the letter (e.g., 225 in P225/70R16) shows the tire’s width in millimeters from sidewall to sidewall. The correct width affects stability, traction, and overall performance.

Aspect Ratio

The aspect ratio (e.g., 70 in P225/70R16) indicates sidewall height as a percentage of width. A 70% ratio means the sidewall height is 70% of the width. Higher aspect ratios provide a cushioned ride, while lower ones offer sharper handling. At Hale’s, we can help find the right balance for local driving conditions.

Construction

The “R” in the code stands for radial construction, the standard for most modern tires. Radial construction provides flexibility, long tread life, and fuel efficiency, suitable for everyday driving.

Wheel Diameter

The final number (e.g., 16 in P225/70R16) shows the wheel diameter in inches, ensuring the tire fits a 16-inch wheel. A correct match is crucial for fit and safety, as mismatched sizes may lead to alignment issues and uneven wear.

Key Considerations When Choosing Tires

Choosing the right tire goes beyond just reading the size. Consider the following factors to make a well-informed choice:

  • Load Index: This number specifies the tire’s load-carrying capacity. You’ll find it on the tire’s sidewall, often in pounds or kilograms.
  • Speed Rating: Found as a letter on the sidewall, this tells the maximum speed capability of the tire. For instance, an “H” rating means the tire can handle up to 130 mph.
  • Treadwear Grades: These grades predict the expected lifespan of the tire’s tread. Tires with higher treadwear grades generally last longer, offering better value over time.
