Euro-Metric System
The ‘Euro-Metric’ system is used in most other parts of the world and uses a slightly different measurement system. The tire size is indicated by a combination of numbers, and the load capacity is denoted by a number or letter. The load capacity is usually indicated by a number in a circle, while the load capacity rating is usually indicated by a letter (e.g. ‘H’, ‘V’, ‘W’, ‘Y’, etc.). Here’s an example of how to read the tire size using the Euro-Metric system:
“195/60R15 88H”
This tire is a 195 mm wide tire with a 60% aspect ratio and a diameter of 15 inches. It has a maximum load capacity of 880 pounds and is rated for a maximum speed of 130 mph.
Identifying the Speed Rating on the Tire
The speed rating on a tire is denoted by a letter (e.g. ‘H’, ‘V’, ‘W’, ‘Y’, etc.). The speed rating indicates the maximum speed at which the tire can safely operate. Here’s a breakdown of the different speed ratings and their corresponding maximum speeds:
*

Tire Label Data Interpretation
Tire labels are an essential part of any tire’s packaging, providing vital information about the tire’s performance, safety, and durability. These labels are designed to help drivers make informed decisions about their tire purchases, maintenance, and use. In this section, we’ll delve into the world of tire labels, explaining how to interpret the data, creating a comparison chart, and providing a step-by-step guide for calculating the tire’s rolling circumference and load-carrying capacity.
Coding for Tire Label Data
Tire labels are encoded with a set of standardized symbols and codes, which provide valuable information about the tire’s characteristics, including its speed rating, load rating, traction, and temperature resistance. Let’s take a closer look at these codes:
- Speed Rating:
- Example: a Q-rated tire can handle speeds up to 99 mph (160 km/h), while an H-rated tire can handle speeds up to 130 mph (210 km/h).
- Load Rating:
- Example: a tire with a load rating of 91H can support a maximum load of 1,279 pounds (580 kg) per tire.
- Traction and Temperature Resistance:
- Example: a tire labeled with the symbol “A” for traction and “B” for temperature resistance can handle various traction conditions and limited temperature extremes.
- Aspect Ratio:
- Example: a tire with an aspect ratio of 60 can be considered a 60% sidewall height in relation to its diameter.
The speed rating is indicated by a letter, such as Q, R, S, T, or H. This indicates the maximum speed the tire can handle safely.
The load rating is indicated by a number, which represents the maximum load the tire can support. This is usually expressed in pounds or kilograms.
Tire labels also indicate the tire’s traction and temperature resistance capabilities using symbols.
The aspect ratio is indicated by a number, which represents the height of the sidewall in relation to the tire’s diameter.
Deciphering the Tire Label Code
Let’s use the example of a tire labeled “91H R Q”. Breaking down this code, we can see that it indicates the following:
- Tire Size:
- Example: a 91H tire has a diameter of approximately 27.5 inches (700 mm) and a width of 9.2 inches (234 mm).
- Aspect Ratio:
- speed rating:
- load capacity:
The load capacity is calculated as a portion of the load rating (91 pounds or 41 kilograms per tire) that the tire is designed to handle at a particular inflation pressure.
- Tread Depth:
- Example: a tire with a tread depth of 10 mm can handle water on the road and provide the desired traction.
The tire size is typically indicated by the number and letter sequence (e.g., 91H).
The aspect ratio is typically indicated by the first number and letter sequence
The tread depth is typically indicated by a measurement in millimeters or inches.
Calculating the Tire’s Rolling Circumference and Load-carrying Capacity
To calculate the tire’s rolling circumference, you’ll need to know the tire’s diameter and use the following formula:
- Rolling Circumference = π x Diameter
- Example: a tire with a diameter of 27.5 inches (700 mm) will have a rolling circumference of approximately 86.6 inches (220 mm).
The load-carrying capacity, on the other hand, can be calculated by multiplying the load rating by the speed rating.
- Load-carrying Capacity = Load Rating x Speed Rating
- Example: a tire with a load rating of 91 pounds (41 kg) and a speed rating of Q can handle a maximum load of approximately 1,279 pounds (580 kg) per tire.
These calculations can be performed using a calculator or online tool, making it easier to make informed decisions about tire purchases and maintenance.

Understanding Tire Age and Expiration
Tires have expiration dates, but what does that mean? Don’t worry, we’ll break it down for you. The expiration date is not the same as the manufacture date, and it’s essential to understand the difference.
The manufacture date is the date when the tire was produced, usually indicated by a series of numbers and letters on the sidewall. It’s like the born date of the tire! On the other hand, the expiration date is the date after which the tire is no longer considered safe for use. This is usually indicated by a similar series of numbers and letters on the sidewall, but it’s often abbreviated as “DOT” (Department of Transportation).
Difference between Manufacture and Expiration Date
The manufacture date is the day when the tire was produced, while the expiration date is the day after which the tire is considered to be no longer safe for use. This is because tires degrade over time due to exposure to sunlight, heat, and other environmental factors.
Example Tire Label
Here’s an example of a tire label that shows the manufacture date and expiration date:
DOT Number: 35X-456-12
Manufacture Date: 35 (week 35) – 2020 (year)
Expiration Date: 45 (week 45) – 2022 (year)
In this example, the tire was manufactured in week 35 of 2020 and expires in week 45 of 2022. This means that if you buy this tire in January 2022, it will expire in August 2022.
Tire Age and Expiration Tracking System
A simple system for tracking tire age and expiration could be implemented as follows:
- Record the manufacture date and expiration date of each tire.
- Keep track of the current date and age of the tire.
- Alert the driver or maintenance personnel when the tire reaches its expiration date.
This system can be implemented using a spreadsheet or a database, and it’s essential for ensuring that tires are replaced before they expire.
Tires That Have Passed Their Expiration Date but Are Still Safe to Use
While it’s not recommended to use tires past their expiration date, there are some examples of tires that have been deemed safe to use after their expiration date. For instance, some tires that were manufactured in the 1980s and 1990s are still in use today because they have been properly maintained and have not shown any signs of wear and tear.
However, it’s essential to note that using a tire past its expiration date can be hazardous, and it’s not worth the risk. Always follow safety guidelines and replace your tires regularly to ensure your safety on the road.
