Imagine you’re looking at tires for your vehicle, and you come across a string of seemingly cryptic numbers and letters like 195/65R15 105v. You might find yourself wondering, “Is this tire talk, or a secret code that only auto mechanics understand?”
Well, fear not, dear reader! By the end of this enlightening article, you will not only be able to decipher this rubbery riddle, but you might also impress your local mechanic with your newfound tire lingo. Ready to decode? Let’s roll!
What does 105t, 105s, 105q, 105h, 105r, 105v, 105w mean on a tire?
These alphanumeric codes represent the Load Index and Speed Rating of the tire. The Load Index (105 in this case) indicates the maximum load that the tire can safely carry, while the letter following it (like T, S, Q, H, R, V, W) is the Speed Rating, which signifies the maximum speed at which the tire can safely travel.
Here’s a breakdown of what these specific codes mean:
|Load Index (LI)
|Maximum Load (kg)
|Maximum Speed (km/h)
The “R” is a little special; it’s not a speed rating but refers to “Radial”, which is a design characteristic of the tire. Now, before we get carried away dreaming about hitting the 270 km/h mark, let’s dive a little deeper.
What does 105T mean on a tire?
105T is a specific combination of Load Index and Speed Rating on a tire. Let’s break it down:
- 105: The Load Index of 105 suggests that each tire can support a maximum weight of 925 kg. However, don’t get caught in the trap of multiplying this number by four and assuming that’s your car’s carrying capacity. The actual load your vehicle can carry is also dependent on its design and specifications. So while your tires might happily bear the weight, your car’s suspension may give you the cold shoulder!
- T: This is the Speed Rating. A tire with a T rating is designed to perform optimally up to speeds of 190 km/h. This doesn’t mean you should start testing the speed limits on public roads, though. Safety first!
To add some context, 105T-rated tires are commonly found on medium to large sedans and family minivans. These vehicles are designed with comfort and safety in mind, not high-speed performance. Therefore, a T rating (190 km/h) is more than sufficient, considering the average highway speed limits worldwide are well below this.
All about 105T tire
- Versatility: 105T tires are the jack-of-all-trades in the tire world. They’re designed to give you a comfortable ride while providing excellent all-season performance. Whether it’s a quick dash to the supermarket or a long-distance road trip, these trusty tires have got your back.
- Safety: 105T tires are designed to prioritize safety over speed, a feature highly valued by families. They provide stable handling and improved traction in most driving conditions. Remember, the “T” here stands for “Trustworthy” (I’m kidding – it doesn’t, but it’s a good way to remember!).
- Durability: Many 105T tires are designed to last with high treadwear ratings. These tires will stay with you through thick and thin, like a loyal golden retriever.
- Fuel Efficiency: Some 105T tires offer low rolling resistance, improving fuel efficiency. These tires care about the environment as much as they care about your wallet!
What does 105S mean on a tire?
My dear reader, if you’ve ever spent time admiring your tire and noticed the inscription ‘105S’, I’m sure you’ve wondered, “What on Earth does that mean?” Fear not, because I’m here to demystify this rubbery enigma for you.
The ‘105S’ on a tire refers to two specific things: the Load Index and Speed Rating. This particular tire, my friend, can carry a weight up to 925 kg and still happily roll around at speeds up to 180 km/h. Let’s delve a little deeper into what this all means:
Load Index: The Heavyweight Champion
- 105: This number is the Load Index, and it represents the maximum load the tire can safely carry when inflated to its maximum safe pressure. In this case, 105 signifies that your tire can carry up to 925 kg of load. But hold on, don’t start loading your car with a family of polar bears just yet! Remember that this is the load per tire, and the overall load your vehicle can carry also depends on other factors, like the vehicle’s suspension system.
Speed Rating: The Sprinter
- S: Now, the ‘S’ in 105S is the Speed Rating. This letter indicates the maximum speed the tire can sustain for a ten-minute endurance without its soul (read: rubber) giving up on you. An ‘S’ rating means the tire is certified to perform up to 180 km/h. While this might seem like a great invitation to test the limits on an open road, always remember to follow speed regulations and prioritize safety. After all, nobody likes a show-off!
The Story of the 105S Tire
- Versatility: A 105S tire is like that reliable friend who is always ready to help. Whether you’re commuting, going on a long drive, or making an emergency trip to a late-night fast-food drive-through, these tires are there for you.

The ‘105Q’ on a tire indicates both the Load Index and Speed Rating. In this case, 105 denotes a maximum load capacity of 925 kg, while ‘Q’ indicates a top speed capability of 160 km/h. Here’s a more detailed exploration:
Load Index: The Muscle
- 105: This number, the Load Index, represents the maximum weight this tire can safely carry. If 105Q were a wrestler, it would be in the heavyweight class, able to carry a load of up to 925 kg. But remember, a car is a team sport, and your vehicle’s actual carrying capacity depends on other factors, too, like the strength of your suspension system.
Speed Rating: The Long-distance Runner
- Q: The ‘Q’ in 105Q is the Speed Rating. Think of it as the tire’s maximum speed limit while carrying its designated load. A ‘Q’ rated tire can safely sustain speeds of up to 160 km/h. While this might not break any land-speed records, remember that slow and steady wins the race!
The Profile of a 105Q Tire

Recap And Summary
Cracking the code on your tire’s sidewall doesn’t have to feel like you’re deciphering ancient runes. We’ve decoded the meaning of 105T, 105S, 105Q, 105H, 105R, 105V, and 105W in relation to tires. These symbols represent your tire’s Load Index and Speed Rating, two critical factors that determine the load-carrying capacity and safe operating speed of your tire. Understanding these tire markings can help ensure you select the correct tire for your vehicle and driving needs, providing safety, performance, and peace of mind.
Let’s tackle some common questions that arise when comparing these tire markings:
105H vs 105T
Both 105H and 105T tires can carry a load of up to 925 kg. However, while the 105H tire can safely reach speeds of up to 210 km/h, the 105T tire is rated for maximum speeds of 190 km/h. Thus, if high-speed driving is a key factor for you, the 105H tire might be more suitable.
105H vs 105V
The load index for both is 105, which means both can carry a load up to 925 kg. However, while the 105H tire can safely reach speeds of up to 210 km/h, the 105V tire can reach up to 240 km/h. For drivers seeking a tire for high-speed performance, the 105V could be a better fit.
105H vs 105W
Both these tires have a load index of 105, so they can carry up to 925 kg. But in terms of speed, the 105W tire, with a speed rating of 270 km/h, leaves the 105H tire, with its 210 km/h speed rating, in the dust. If speed thrills you, consider the 105W.
105W vs 105Y
Both these tire types can safely carry up to 925 kg. However, when it comes to speed, the 105Y tire, with a speed rating of 300 km/h, outpaces the 105W tire, which is rated for a maximum speed of 270 km/h. If you have a need for speed, the 105Y tire might be your best bet.
105W vs 105V
Both these tire types have a load index of 105, meaning they can carry up to 925 kg. However, when it comes to speed, the 105W tire has a speed rating of 270 km/h, which is higher than the 105V tire’s rating of 240 km/h. If high-speed performance is important to you, the 105W tire may be the right choice.
Decoding the numbers and letters on your tires might initially seem confusing, but now you’re armed with the knowledge to make informed decisions. Remember, while the load index and speed rating are important considerations when choosing a tire, they are not the only factors. Always consider your driving conditions, climate, vehicle type, and personal driving style before making a tire purchase. Whether you’re the ‘slow and steady’ or ‘fast and furious’ type, there’s a tire out there with your name on it – well, technically with your number and letter on it! So tread wisely!
