Tires are a crucial component of any vehicle, providing the necessary traction, stability, and control for safe driving. With so many different types of tires available, it can be challenging to understand the various markings and codes that appear on them. One such code that may leave many drivers puzzled is “98T.” In this article, we will delve into the meaning behind this code and explore its significance in the world of tires.
The importance of understanding tire codes cannot be overstated. These codes provide valuable information about the tire’s performance, durability, and compatibility with different vehicles. By deciphering the meaning behind these codes, drivers can make informed decisions when selecting the right tires for their vehicle, ensuring optimal performance, safety, and fuel efficiency.
What Does 98T Mean on a Tire?
The “98T” code on a tire refers to the tire’s load index and speed rating. Let’s break down each component of this code:
The first digit, “98,” represents the tire’s load index. This is a numerical value that indicates the maximum weight that the tire can support. The higher the load index, the more weight the tire can handle. In this case, the load index of 98 indicates that the tire can support a maximum weight of 1,669 pounds (757 kg) for a single tire, and 3,338 pounds (1,514 kg) for a pair of tires.
The second letter, “T,” represents the tire’s speed rating. This letter indicates the maximum speed at which the tire is designed to operate. In this case, the “T” speed rating indicates that the tire is designed for speeds up to 118 mph (190 km/h). The “T” speed rating is one of the highest speed ratings available, making it suitable for high-performance vehicles.
Tire Load Index Explained
The tire load index is a critical component of the “98T” code. It indicates the maximum weight that the tire can support, which is essential for ensuring the safety and stability of the vehicle. Here’s a breakdown of the tire load index: (See Also: Can You Drive With A Faulty Tire Pressure Sensor? Risks To Know)
The load index is a numerical value that ranges from 71 to 150. The higher the load index, the more weight the tire can handle. For example:
| Load Index | Maximum Weight (Single Tire) |
|---|---|
| 71 | 441 pounds (200 kg) |
| 81 | 551 pounds (250 kg) |
| 98 | 1,669 pounds (757 kg) |
| 110 | 2,205 pounds (1,000 kg) |
It’s essential to note that the load index is not the same as the tire’s maximum weight capacity. The maximum weight capacity is determined by the vehicle’s manufacturer and is typically lower than the tire’s load index.
Tire Speed Rating Explained
The tire speed rating is another critical component of the “98T” code. It indicates the maximum speed at which the tire is designed to operate, ensuring safe and stable driving. Here’s a breakdown of the tire speed rating:
The tire speed rating is a letter that ranges from “Q” to “V.” The higher the speed rating, the higher the maximum speed. For example:
| Speed Rating | Maximum Speed (mph) |
|---|---|
| Q | 99 mph (159 km/h) |
| R | 106 mph (171 km/h) |
| S | 112 mph (180 km/h) |
| T | 118 mph (190 km/h) |
| U | 124 mph (200 km/h) |
| V | 149 mph (240 km/h) |
It’s essential to note that the tire speed rating is not the same as the vehicle’s top speed. The vehicle’s top speed is determined by its engine, transmission, and other factors, while the tire speed rating is specific to the tire itself. (See Also: What Causes Bulge in Tire Sidewall?

How to Choose the Right Tire
With so many different types of tires available, choosing the right one can be overwhelming. Here are some tips to help you make an informed decision:
- Check the vehicle’s manufacturer recommendations: The vehicle’s manufacturer will recommend a specific tire size and type for your vehicle.
- Consider the vehicle’s intended use: If you drive a high-performance vehicle, you may want to choose a tire with a higher speed rating.
- Check the tire’s load index: Make sure the tire’s load index matches the vehicle’s maximum weight capacity.
- Consider the tire’s tread life: If you drive in harsh weather conditions, you may want to choose a tire with a longer tread life.
- Check the tire’s warranty: Some tires come with a warranty that covers defects and other issues.
Recap
In conclusion, the “98T” code on a tire refers to the tire’s load index and speed rating. The load index indicates the maximum weight that the tire can support, while the speed rating indicates the maximum speed at which the tire is designed to operate. By understanding these codes, drivers can make informed decisions when selecting the right tires for their vehicle, ensuring optimal performance, safety, and fuel efficiency.
Frequently Asked Questions
What is the difference between the load index and the maximum weight capacity?
The load index is a numerical value that indicates the maximum weight that the tire can support, while the maximum weight capacity is determined by the vehicle’s manufacturer and is typically lower than the tire’s load index.
What is the highest speed rating available?
The highest speed rating available is “V,” which indicates a maximum speed of 149 mph (240 km/h).
Can I use a tire with a higher speed rating than my vehicle’s top speed?
No, it’s not recommended to use a tire with a higher speed rating than your vehicle’s top speed. This can lead to reduced traction and increased risk of tire failure. (See Also: What Is a Load Index on Tires? Essential Guide)
How do I know if my tire is compatible with my vehicle?
You can check the vehicle’s manufacturer recommendations or consult with a tire professional to ensure that the tire is compatible with your vehicle.
What happens if I exceed the tire’s speed rating?
Exceeding the tire’s speed rating can lead to reduced traction, increased risk of tire failure, and potentially even a blowout. It’s essential to follow the recommended speed rating to ensure safe and stable driving.
