Deciphering Your Hyundai’s Tire Sidewall Labeling
Deciphering Your Hyundai’s Tire Sidewall Labeling
Posted on October 17, 2023
Understanding tire sidewall labeling on your Hyundai is crucial for vehicle safety, optimal performance, and to ensure the correct tire selection. Here is a comprehensive breakdown to help you understand the crucial information embedded on your tire’s sidewall:
1. Manufacturer or Brand Name
This represents the manufacturer or the brand of the tire, providing insight into the quality and reliability you can expect from the tire.
2. Tire Size Designation
A tire’s sidewall is marked with its size designation, crucial when selecting replacement tires. For example, in the designation 245/60 R18 105H:
- 245: Represents tire width in millimeters.
- 60: Aspect ratio; the tire’s section height as a percentage of its width.
- R: Denotes radial tire construction.
- 18: Rim diameter in inches.
- 105: Load index; a numerical code related to the maximum load the tire can carry.
- H: Speed rating symbol; represents the tire’s designed maximum safe operating speed.
3. Wheel Size Designation
Just like tires, wheels are marked with important information. For instance, in 7.5J X 18:
- 7.5: Rim width in inches.
- J: Rim contour designation.
- 18: Rim diameter in inches.
4. Checking Tire Life (TIN: Tire Identification Number)
Tires over six years old should be replaced. The manufacturing date is designated by the last four digits of the DOT code on the tire sidewall, indicating the week and year of manufacture.
5. Tire Ply Composition and Material
This indicates the number of layers or plies of rubber-coated fabric in the tire and the materials used, which include steel, nylon, polyester, etc. The letters “R”, “D“, and “B” represent radial ply, diagonal or bias ply, and belted-bias ply construction respectively.
6. Maximum Permissible Inflation Pressure
This number is the highest amount of air pressure that can be put in the tire. Exceeding this pressure is hazardous, and thus, adherence to recommended inflation pressure is vital.
7. Maximum Load Rating
This number reveals the maximum load in kilograms and pounds that the tire can carry. When replacing tires, always use a tire with the same load rating as the factory-installed tire.
Understanding the tire sidewall labeling on your Hyundai can significantly impact your vehicle’s performance, safety, and the longevity of the tires. Regularly checking these components, alongside adherence to recommended pressures and load ratings, will ensure a smoother and safer driving experience.
