As an enthusiast, you may find yourself wondering about those strange letters on your tires, those that follow the mysterious “111”. Let’s take a humorous yet informative ride down the lane of tire markings, shall we? Brace yourself as we blow your mind with tire terminology!
What does 111T, 111S, 111Q, 111H, 111R, 111V, 111W Mean on a Tire?
These odd combinations are actually more helpful than you might think, especially when it’s time to replace your tires. Each of these lettering (T, S, Q, H, R, V, W) indicates the tire’s speed rating, and the “111” preceding them refers to the tire’s load index.
The speed rating is a measure of the maximum speed the tire can safely maintain over time, while the load index is a numerical code associated with the maximum load a tire can carry at the speed indicated by its speed symbol under specified conditions.
Now, let’s visualize this information with a table:Load Index and Speed Rating Max Speed (mph) Suitable For 111T 118 Family Sedans and Vans 111S 112 Family Sedans and Vans 111Q 99 Certain Winter Tires 111H 130 Sport Sedans and Coupes 111R 106 Light Trucks 111V 149 Sports Cars 111W 168 Exotic Sports Cars
What does 111T Mean on a Tire?
When you see ‘111T’ on a tire, it tells you two key things about that tire’s capabilities. This alphanumeric combination, ladies and gentlemen, is not some secret tire manufacturers’ code for a hidden treasure but a way to communicate important tire performance specifications to us, the users. Let’s break it down:
- 111: The first part, the number 111, is known as the ‘Load Index.’ This number represents the maximum weight the tire can safely support when it’s fully inflated. Specifically, a load index of 111 can support up to 2,403 lbs. or 1,090 kg. So, if you’ve been wondering if those extra gym sessions are taking a toll on your tires, you’ve got your answer!
- T: The second part of the code, the letter ‘T,’ is known as the ‘Speed Rating.’ A tire with a speed rating of ‘T’ is designed to be safe and reliable up to a maximum sustained speed of 118 mph or 190 km/h. Just don’t use this as an excuse to channel your inner speed demon on regular roads; remember, safety first!
What does 111S Mean on a Tire?
Alright, we’ve cracked the ‘T’ code, but what about ‘S’? You’ve guessed it! It follows the same pattern.
- 111: The number part remains consistent; it’s still our friend the ‘Load Index.’ A 111 load index means the tire can carry a load of up to 2,403 lbs. or 1,090 kg when fully inflated.
- S: Now, let’s tackle the mystery letter. ‘S’ is another ‘Speed Rating.’ If you have an ‘S’ rating on your tire, it means the tire is built to handle up to 112 mph or 180 km/h sustained speeds. This rating is commonly found
What Does 111Q Mean on a Tire?
The “111Q” rating on a tire may seem like a weird secret code. It’s like the tire is whispering to you, “Hey, I can do some cool stuff, but you need to decipher this first”. But fear not, tire detective! We’re here to crack this enigma for you.
- 111: The load index, a.k.a, the tire’s weightlifting score. Just like a weightlifter boasting about their deadlift personal best, ‘111’ shows that your tire can carry a weight of up to 2,403 lbs. or 1,090 kg. So next time you go on a road trip, remember, your tire has got you covered.
- Q: Now for the second part of our mystery code, ‘Q.’ It’s the tire’s ‘Speed Rating.’ If your tire is rated ‘Q,’ it means that it can safely sustain speeds of up to 99 mph or 160 km/h. It’s common in certain winter tires, as these are designed for stability in tricky conditions rather than high-speed racing. So, no need to rush like a NASCAR driver in a snowstorm, your tire knows how to chill!
What Does 111H Mean on a Tire?
Continuing our journey into tire talk, next up is ‘111H’. Before you start imagining it as a model number of a secret spy car, let’s break down what it really means.
- 111: This part remains consistent throughout our tire talks. It’s the tire’s ‘Load Index.’ So, if your tire has ‘111’ written on it, it can carry a weight of up to 2,403 lbs. or 1,090 kg when it’s fully inflated. Handy, right?
- H: Now, for the mysterious letter ‘H.’ It’s the tire’s ‘Speed Rating.’ An ‘H’ rated tire is like the action hero of tires, built to withstand sustained speeds of up to 130 mph or 210 km/h. It’s often found on sport sedans and coupes. So if you drive one of these and wonder, “Can my car go fast?”, the answer is, “Yes, your tire can handle it!”
What Does 111R Mean on a Tire?
Finally, we arrive at the intriguing ‘111R’. Let’s declassify this tire’s secrets.
- 111: The ‘Load Index’ part of the code remains the same. A tire marked with ‘111’ has been bench pressing in the tire gym and can support a weight of up to 2,403 lbs. or 1,090 kg.
- R: The letter ‘R’ represents the ‘Speed Rating.’ In the tire world, an ‘R’ rated tire is like the reliable, strong character in every movie, not the fastest, but gets the job done. It’s capable of sustained speeds up to 106 mph or 170 km/h, and it’s most commonly found on light trucks. So if you’re planning on hauling some heavy stuff, your tire is saying, “Bring it on!”
What Does 111V Mean on a Tire?
Taking a peek at our next tire marking, we stumble upon the cryptic ‘111V’. No, this is not an alternate code for a secret handshake, but an essential piece of information for your vehicle. Let’s decipher it:
- 111: The load index ‘111’ remains constant throughout our tire marking voyage. It indicates that your tire is like the Hercules of the tire world, capable of carrying up to 2,403 lbs. or 1,090 kg.
- V: The ‘V’ stands for the ‘Speed Rating.’ Picture a cheetah running across the savannah; that’s your ‘V’ rated tire. It can handle sustained speeds of up to 149 mph or 240 km/h. ‘V’ rated tires are commonly found on sports cars. So, if you’re channeling your inner Lewis Hamilton, remember your tire is up to the challenge!
What Does 111W Mean on a Tire?
Finally, we’ve reached ‘111W’, the last but not least of our tire markings.
- 111: By now, the load index ‘111’ should feel like an old friend. It’s still here to tell you that the tire can safely carry up to 2,403 lbs. or 1,090 kg.
- W: The ‘W’ stands for the ‘Speed Rating.’ This rating is the epitome of speed in the tire world, designed for the speed demons amongst us. It can handle sustained speeds up to 168 mph or 270 km/h, often found on exotic sports cars. If you’re pushing the pedal to the metal, this tire won’t let you down!

111T vs 111H: What’s the difference?
The primary difference lies in the speed rating. ‘T’ rated tires can sustain speeds up to 118 mph, while ‘H’ rated tires can go up to 130 mph. So if speed thrills you, ‘H’ may be your choice.
111T vs 111S: Which is better?

111V vs 111W: Which should I choose?
‘V’ rated tires can handle speeds up to 149 mph, while ‘W’ rated tires can go up to 168 mph. If you’re driving a high-performance vehicle and speed is crucial for you, ‘W’ might be the better choice.
111V vs 107T: What’s the difference?
The differences lie in both the load index and the speed rating. ‘111V’ can carry more weight and sustain higher speeds than ‘107T’. Consider your vehicle’s needs and your driving habits to make a decision.
Recap and Summary
Tire markings like ‘111T’, ‘111S’, ‘111Q’, ‘111H’, ‘111R’, ‘111V’, and ‘111W’ are there to help you understand the capabilities of your tire.
