HOW TO FIND YOUR TIRE SPEED RATING
If you’re wondering what tire speed rating your vehicle manufacturer recommends, simply look in the manual. You might also find it in the driver’s side door jamb, the gas tank hatch, or inside the glove box door – anywhere that lists the right tire code for your vehicle.
DETERMINING TIRE SPEED RATING
Speed ratings are the product of laboratory testing – with simulated speeds and loads. To receive any kind of rating, a tire must demonstrate that it’s capable of sustaining a particular speed. Industry standards govern the process of reaching and maintaining a given speed during a test.
TIRE SPEED RATING SYSTEM QUIRKS AND ANOMALIES
Today’s speed rating system uses letters A through Z. Each letter corresponds to a specific speed. In general, that speed goes up as the rating advances alphabetically. For example, a tire rated “L” is good for a lower maximum sustained speed than one rated “N.”
COMMON TIRE SPEED RATINGS CHART
The following speed ratings are those you’re most likely to encounter for ordinary vehicles. They begin with a maximum speed of 118 mph (190 kph) and increase from there.
What is a T rating?
A T rating indicates the tire is approved for speeds up to 118 mph (190 km/h) under optimal conditions. T ratings are most associated with standard touring tires, and everyday passenger vehicles like family sedans and minivans.
What does a Z rating mean?
A Z rating indicates the tire has been approved for speeds of 149+ mph (240+ km/h) under optimal conditions. This rating is associated with maximum tire performance and is a match for performance coupes and sedans, sports cars, and supercars. While speed rating is typically adjacent to the load index, and outside of (after) the tire size expression, the Z speed rating can be found within the structure of the tire size:
How fast can a Q tire go?
Q tires are approved for speeds up to 99 mph (160 km/h) under optimal conditions. Tires toward the low end of the speed rating range often prioritize a particular function or unique performance over maximum speed rating. Some studdable and studless winter tires, for example, are Q speed rated.
What is the speed restriction on a Z tire?
To understand the speed restriction of a Z speed rated tire, refer to the additional speed rating adjacent to the load index. In the case of a Z tire, the speed rating will either be W, Y, or (Y).
What is the tire number on an Audi A3?
In the doorjamb image above (belonging to an Audi A3), the car’s tire information is: 225/45R17 94H. In this example, 94H is the service description, with the 94 indicating load index, and the H indicating speed rating.
What Is Tire Speed Rating?
A tire’s speed rating indicates the optimal speed that the tire can safely maintain over time. In short, it’s the fastest speed a tire can handle before it no longer performs as designed. The higher the speed rating, the better control and handling you’ll have at higher speeds.
Why Were Tire Speed Ratings Developed?
The speed rating system used today was developed in Europe in response to the need to control the safe performance of tires at standardized speeds. When the rating system was originally developed, the "Unlimited V" category of over 210 km/h (130 mph) was the top speed rating possible.
Where Can I Find My Tire Speed Rating?
You can find your tire speed rating in a number of places, typically in the owner’s manual, driver’s side doorjamb, glove box door, and gas tank hatch. Recent standardization has changed so all ratings except "Unlimited ZR" incorporate the speed symbol and load index as part of every tire’s service description on the tire’s sidewall.
ZR Designation
Tires having a maximum speed capability over 149 MPH may have “ZR” in the size designation. Tires with a maximum speed capability over 186 MPH are required to include “ZR” in the designation. Below are examples of tire sizes with a “ZR” speed rating.
Tire Speed Rating Chart
For tires with a maximum speed capability higher than 240 km/h (149 mph), a "ZR" may appear in the size designation. Tires with a maximum speed capability higher than 300 km/h (186 mph), require a "ZR" in the size designation. Consult the tire manufacturer for maximum speed when there is no service description.

What does the tire speed rating mean?
Every car tire comes with a specific speed and load capacities. The tire speed rating is the maximum speed that a tire can reach under recommended loads for a sustained amount of time under ideal operating conditions. Higher speed ratings provide better handling and control characteristics at higher speeds.
Why Were Speed Ratings Developed?
Tire manufacturers adopt different manufacturing processes and standards. Speed ratings were introduced as a means to control and ensure the safe performance of diverse tire brands at standardized operating speeds. Initial speed ratings designated unlimited V (over 130 mph) as the highest tire speed rating.
Places to Look for Tire Speed Rating
The speed rating is usually simple to identify as it appears as the last item in the tire’s size code. Car manufacturers recommend specific speed ratings that are included in the car manual.
What Are Z Rated Tires?
Before explaining the ZR designation, first, let’s look at the other ratings. The speed rating ranges from 75 mph and goes over 186 mph. Each increase is several miles per hour higher than the previous one and gets a letter that helps you identify the rating quickly.
Tire Speed Rating Chart
A speed rating chart is used to indicate the standard maximum speed capacities for different types and sizes of tires under optimal operating conditions. Speed ratings are designated using alphabetic symbols, A to Z, with the exclusion of I, O, and U.
FAQ
Yes. Higher tire ratings provide better car handling and control at higher speeds. Highly rated tires have a better grip on the road, characterized by improved braking characteristics. Highly rated tires, however, wear and tear faster than low rated ones.
How to determine tire speed rating?
How are Speed Ratings Determined? 1 For the ECE test, the tire is properly inflated and mounted on a wheel attached to a testing machine in a room that’s heated to 77 degrees F. 2 The tire is pressed against a metal drum with enough pressure to simulate a realistic load. 3 Starting at a speed 40 km/h lower than the proposed rating level, the tire is spun for 10-minute increments at higher and higher speeds, until it reaches the target speed. 4 The tire spins for 10 minutes at the target speed. 5 It’s then removed from the machine and inspected for any failures, like separation of tread components. If it’s intact, it passes the speed rating. 6 Sometimes an SUS (step-up speed) test will be added after the tire performs at the target speed rating. Speed is increased until the tire fails. 7 If the tire is being tested at the SAE standard, it’s required to run for an hour at target speed in a room heated to 100 degrees.
What is a SUS test?
Sometimes an SUS (step-up speed) test will be added after the tire performs at the target speed rating. Speed is increased until the tire fails. If the tire is being tested at the SAE standard, it’s required to run for an hour at target speed in a room heated to 100 degrees.
Can you mix and match tires?
If you’re replacing tires and think you may want a lower- or higher-speed-rated tire, it’s best not to mix and match. When mounting differently rated tires, techs prefer to put the lower-speed-rated ones on the front to prevent oversteering.
What is speed rating?
SPEED RATINGS REFER TO MORE THAN JUST SPEED. Contrary to the name, speed ratings aren’t just about speed. They’re also about ride comfort, wear and cornering ability. Typically, the higher the speed rating, the better the grip and stopping power, but the lower the tread life. You can always increase the speed rating of the tires on your vehicle ...
