by

Understanding the markings on your Ford tire sidewall is essential for ensuring safety, proper maintenance, and optimal performance. These markings provide vital information about the tire’s size, type, manufacturing details, and performance ratings. Learning how to interpret these markings can help you make informed decisions when replacing or inspecting tires.

Key Tire Sidewall Markings

Most tire sidewalls feature a series of alphanumeric codes and symbols. These markings include the tire size, load index, speed rating, manufacturing date, and other important details. Familiarizing yourself with these can help you select the right tires for your Ford vehicle and maintain safety standards.

Tire Size

The tire size is typically displayed as a sequence like P215/60R16. Here’s what each part indicates:

  • P: Tire type (Passenger car)
  • 215: Tire width in millimeters
  • 60: Aspect ratio (height to width ratio)
  • R: Radial construction
  • 16: Diameter of the wheel in inches

Load Index and Speed Rating

Located after the tire size, these codes indicate the maximum load capacity and the maximum speed the tire can handle safely. For example, 95H:

  • 95: Load index (e.g., 1,521 lbs)
  • H: Speed rating (up to 130 mph)

Manufacturing Details

The manufacturing date is indicated by a four-digit code, such as 3219. The first two digits represent the week of manufacture, and the last two indicate the year. For example, 3219 means the tire was made in the 32nd week of 2019.

Additional Markings to Know

Other important symbols and markings include:

  • TWI: Tread Wear Indicator, shows when the tire needs replacing
  • DOT: Department of Transportation code, indicating compliance and manufacturing location
  • UTQG: Uniform Tire Quality Grading, provides traction, temperature, and tread wear ratings

By understanding these markings, Ford owners can better maintain their vehicles, ensure safety, and select the appropriate tires for their driving needs. Always consult your vehicle’s manual or a professional for specific tire recommendations.
