Tires are an essential component of any vehicle, and understanding the various markings and codes on them is crucial for maintaining proper tire pressure, ensuring safety on the road, and extending the lifespan of your tires. One common code you may come across is “T+H” on the sidewall of your tire. In this article, we will delve into the meaning of T+H and what it indicates about your tire.
What Does T+H Mean On Tires?
The “T+H” code is a designation that indicates the tire’s load index and speed rating. Load index is a numerical value that represents the maximum weight a tire is designed to carry, while speed rating is a letter that indicates the maximum speed at which the tire can safely operate.
Load Index
The load index is a numerical value that ranges from 71 to 150. A higher load index indicates that the tire is designed to carry heavier loads. For example, a load index of 80 indicates that the tire is designed to carry a maximum load of 80 pounds per square inch (psi). It’s essential to check the load index of your tire to ensure it is suitable for your vehicle’s weight and cargo capacity.
Speed Rating
The speed rating is a letter that indicates the maximum speed at which the tire can safely operate. The most common speed ratings are Q, R, S, T, U, H, V, W, and Y. The speed rating is determined by the tire’s construction, rubber compound, and other factors. For example, a tire with a speed rating of H is designed for high-speed driving and can safely operate at speeds up to 130 mph.
Conclusion
In conclusion, the “T+H” code on your tire indicates the load index and speed rating of the tire. Understanding these codes is crucial for maintaining proper tire pressure, ensuring safety on the road, and extending the lifespan of your tires. Always check the load index and speed rating of your tire to ensure it is suitable for your vehicle’s weight and driving habits.
What Does T+H Mean On Tires?
When it comes to tires, there are many abbreviations and acronyms that can be confusing. One such term is T+H, which is often seen on tire sidewalls. In this article, we will delve into the meaning of T+H and what it indicates about your tires.
What Does T+H Stand For?
T+H stands for Treadwear and Traction. It is a rating system used by tire manufacturers to indicate the tire’s performance in two critical areas: treadwear and traction.
Treadwear Rating
The treadwear rating is a measure of how well the tire will wear over time. It is measured on a scale of 100 to 300, with higher numbers indicating better treadwear. The treadwear rating is determined by the tire’s ability to resist wear and tear, and it is influenced by factors such as the tire’s construction, material, and design.
How is the Treadwear Rating Calculated?
The treadwear rating is calculated using a standardized test procedure. The test involves placing the tire on a drum and running it at high speed for a set distance. The tire’s wear is then measured and compared to a reference tire. The resulting rating is a measure of how well the tire performed in the test.
Traction Rating
The traction rating is a measure of how well the tire will grip the road. It is also measured on a scale of 100 to 300, with higher numbers indicating better traction. The traction rating is determined by the tire’s ability to grip the road, and it is influenced by factors such as the tire’s tread pattern, material, and design.

How is the Traction Rating Calculated?
The traction rating is calculated using a standardized test procedure. The test involves placing the tire on a skid pad and applying a controlled amount of force. The tire’s ability to grip the road is then measured and compared to a reference tire. The resulting rating is a measure of how well the tire performed in the test.
What Does the T+H Rating Mean for You?
So, what does the T+H rating mean for you? In simple terms, it means that you can expect the tire to perform well in terms of treadwear and traction. Here are some key points to consider:
* A higher T+H rating indicates better treadwear and traction.
* A lower T+H rating indicates poorer treadwear and traction.
* The T+H rating is just one factor to consider when choosing a tire. You should also consider factors such as the tire’s size, load rating, and speed rating.
* The T+H rating is not a guarantee of performance. Other factors such as road conditions, driving habits, and maintenance can also affect the tire’s performance.
How to Read the T+H Rating on Your Tire
So, how do you read the T+H rating on your tire? Here are some steps to follow:
1.
Locate the T+H rating on your tire sidewall. It should be located near the tire’s size and load rating.
2.
Look for the T+H rating, which will be a series of numbers separated by a plus sign (+). For example, T+H 220.
3.
The first number represents the treadwear rating, which is a measure of how well the tire will wear over time. (See Also: Are 285 Tires 33S)
4.
The second number represents the traction rating, which is a measure of how well the tire will grip the road.
5.
Compare the T+H rating to the manufacturer’s recommended rating for your vehicle. This can be found in your vehicle’s owner’s manual or on the manufacturer’s website.
Conclusion
In conclusion, the T+H rating on your tire is an important indicator of the tire’s performance in terms of treadwear and traction. By understanding what the T+H rating means and how to read it, you can make informed decisions about your tire purchases and ensure that you are getting the best performance from your tires.
Recap
Here is a recap of what we have discussed:
* T+H stands for Treadwear and Traction.
* The T+H rating is a measure of the tire’s performance in these two areas.
* The treadwear rating is a measure of how well the tire will wear over time.
* The traction rating is a measure of how well the tire will grip the road.
* A higher T+H rating indicates better treadwear and traction.
* A lower T+H rating indicates poorer treadwear and traction.
* The T+H rating is just one factor to consider when choosing a tire.
* You should also consider factors such as the tire’s size, load rating, and speed rating.
* The T+H rating is not a guarantee of performance. Other factors such as road conditions, driving habits, and maintenance can also affect the tire’s performance.
Additional Tips
Here are some additional tips to keep in mind:
* Make sure to check your tire’s T+H rating regularly to ensure that it is still within the recommended range.
* Consider rotating your tires regularly to ensure even wear and extend their lifespan.
* Avoid driving on underinflated tires, as this can reduce their treadwear and traction.
* Keep your tires clean and free of debris to ensure optimal performance.
* Consider upgrading to high-performance tires if you drive aggressively or in extreme weather conditions. (See Also: What Is Speed Rating L On Trailer Tires)

What Does T+H Mean On Tires: Frequently Asked Questions
What does T+H stand for on tires?
T+H is an abbreviation that stands for Treadwear and Traction. It is a rating system used by tire manufacturers to indicate the tire’s performance in terms of treadwear and traction. The T+H rating is usually displayed on the tire’s sidewall and is a helpful guide for consumers when selecting the right tire for their vehicle.
How does the T+H rating affect tire performance?
The T+H rating has a significant impact on a tire’s performance. The Treadwear rating measures the tire’s ability to resist wear and tear, while the Traction rating measures the tire’s ability to grip the road. A higher T+H rating generally indicates better performance in both areas. For example, a tire with a T+H rating of 500/500 will have better treadwear and traction than a tire with a rating of 300/300.
Can I use a tire with a lower T+H rating than my vehicle’s recommended rating?
No, it is not recommended to use a tire with a lower T+H rating than your vehicle’s recommended rating. The recommended T+H rating is based on the vehicle’s weight, size, and performance requirements, and using a tire with a lower rating can compromise the vehicle’s safety and handling. It is always best to use a tire with a rating that meets or exceeds the recommended rating.
How do I check the T+H rating on my tires?
The T+H rating is usually displayed on the tire’s sidewall, near the tire’s size and speed rating. You can also check the tire’s information placard, which is usually located on the driver’s side doorjamb or inside the fuel filler door. The placard will list the recommended tire size and T+H rating for your vehicle.
Can I mix and match tires with different T+H ratings?
No, it is not recommended to mix and match tires with different T+H ratings. Tires with different ratings may have different performance characteristics, which can affect the vehicle’s handling and safety.
