A Detailed Guide to Hyundai’s Tire Sidewall Labeling

Hyudnai Service

A tire's sidewall contains crucial information about the tire’s fundamental characteristics, aiding in proper maintenance, tire selection, and identification in case of a recall. Here’s a detailed guide to understanding the tire sidewall labeling on your Hyundai vehicle:

1. Brand or Manufacturer Name

This displays the name of the tire’s manufacturer or brand, providing a quick reference to the tire’s origin and reliability.

2. Decoding Tire Size

The tire size designation is pivotal when choosing replacement tires. For instance, 245/60 R18 105H implies:

  • 245: The width of the tire in millimeters.
  • 60: Aspect ratio, representing the section height as a percentage of the tire’s width.
  • R: Indicates radial construction.
  • 18: The diameter of the rim in inches.
  • 105: Load Index, associated with the maximum load the tire can handle.
  • H: Speed Rating Symbol, indicating the maximum safe operating speed of the tire.

3. Understanding Wheel Size

In the wheel size designation, like 7.5J X 18:

  • 7.5: Refers to the rim width in inches.
  • J: Denotes the rim contour designation.
  • 18: Represents the rim diameter in inches.

4. TIN (Tire Identification Number)

The TIN, found in the DOT code on the tire sidewall, helps determine the tire’s age. Tires over six years old, including the spare, should be replaced. The last four characters of the DOT code represent the week and year of manufacture.

5. Ply Composition and Materials

This section informs about the number and types of plies and the materials used in the tire, such as steel, nylon, polyester. The letters “R”, “D”, and “B” respectively denote radial ply, diagonal or bias ply, and belted-bias ply construction.

6. Maximum Inflation Pressure

This denotes the greatest amount of air pressure permissible in the tire. Maintaining recommended inflation pressure is crucial to avoid tire failure.

7. Load Rating

It specifies the maximum load the tire can bear in kilograms and pounds. It is essential to choose a replacement tire with a load rating equivalent to the original tire to maintain vehicle safety and performance.

Understanding the information on your Hyundai’s tire sidewall is paramount for optimal vehicle performance, safety, and maintenance. Regular checks, adherence to recommended practices, and choosing the right replacement tires based on sidewall information will ensure your vehicle’s longevity and your safety on the road.
