R. Speed rating R allows for speeds up to 106 mph (170 km/h) under optimal conditions. Like Q, R tires generally prioritize a particular function or unique performance over maximum speed capability.
What speed rating is W?
168 mph
SPEED RATING W A relatively new addition to the speed rating chart, tires with speed rating “W” can achieve a maximum sustained speed of 168 mph (270 kph).
What does a W speed rating on a tire mean?
A W speed rating on a tire indicates that the manufacturer produced the tire for use on exotic sports cars. The W rating gives the tire a maximum speed capacity of 168 miles per hour. A tire’s speed rating identifies the highest speed a vehicle should reach. A Y rating, for example, means that the tire can handle speeds up to 186 miles per hour.
What is a “W” or “y” speed rating?
Some tires carry “W” or “Y” speed ratings. Manufacturers may also insert “Z” into the size description (in the tire code data between aspect ratio and diameter) for these kinds of tires. When the speed rating system was first developed, the highest speed rating was the unlimited “V” rating.
What is a V vs W speed rating?
A speed rating is an often-overlooked metric, but it is also a crucial one when it comes to high-performance tires. As such, in this “V vs W Speed Rating” article, we will compare these two ratings and tell you the ins and outs of both. A V-speed-rated tire is one that can comfortably endure speeds up to 149mph or 240kph.
What is a passenger tire speed rating?
Most modern passenger tires bear a tire speed rating, a designation indicating the tire’s designed speed capability. In other words, it’s the fastest speed a tire can handle before it does not perform as designed.
What is R vs ZR tires?
The ZR rating indicates that a tire is capable of high-speed operation, while an R rating indicates that a tire is rated for speeds up to 106 mph. ZR tires are typically used on high-performance vehicles, while R-rated tires are more common on passenger cars.
What are the differences between a ZR and your tyre?
What are the differences between a ZR or R tyre? The Z in ZR corresponds to an old label used by manufacturers to indicate that the speed index is higher than V, i.e. 150 mph. Thus, a ZR tyre has a speed index of V, W, or Y. R indicates that the structure is RADIAL.
What is the difference between Zr and VR?
The Z in ZR corresponds to an old label used by manufacturers to indicate that the speed index is higher than V, i.e. 150 mph. Thus, a ZR tyre has a speed index of V, W, or Y. R indicates that the structure is RADIAL. So, VR indicates that the tyre has a RADIAL structure and a speed index equal to V.
What does ZR mean on a car?
Since automobiles have significantly developed and the car speed has exceeded what was thought impossible – 150 mph, the ZR symbol was created to imply the case. ZR is split into Y, W, and the original Z-rated tires. You can double-check with the tire manufacturers when buying new tires to see what appropriate speed rating you need: W, Y, or Z.
What is ZR speed rating?
Historically, the speed rating ZR on a tire meantthat the construction of the tirecould reach of 150 miles or 240 kilometers per hour. What speed rating is Zr? SPEED RATING SPEED SYMBOL SPEED (mph) ZR* W 168 Y 186 (Y) Above 186
Which is better V or H speed rating?
The major difference between speed rating tires H and V is the tempo. An H tire’s maximum pace operating under favorable circumstances is approximately 130 mph. In contrast, a V-rated tire’s top velocity is slightly faster than an H-rated tire, around 149 mph.
What is the difference between H and V ratings?
The main difference between H and V ratings is the tempo. An H tire’s maximum pace operating is about 130 mph under favorable circumstances. In contrast, a V-rated tire’s top speed is slightly faster than an H-rated tire, around 149 mph. It is the highest-speed wheel that can operate before degradation appears.
What is the difference between V and H tires?
The key takeaway here is that V is a higher speed rating than H. The former can safely travel up to 149mph, while the latter tops out at 130mph. Any more than that, then it will be unsafe to do so. When buying tires, pay attention to the speed rating, as that’s going to be the safe top speed you can reach with your car.
What is the highest speed rating?
When the speed rating system was first developed, the highest speed rating was the unlimited “V” rating. This was for tires whose maximum sustained speed was 149 mph (240 kph) or more.
What does a V rating mean on a tire?
A higher speed value (in this case, a V-rating) typically signifies greater control and handling at higher speeds, as well as the tire’s ability to withstand the added heat. Tires with greater speed ratings, on average, manage better at slower speeds. Do H Or V Rated Tires Last Longer?
What does Z mean on a tire?
SPEED RATING Z While it nearly always means a high performance tire for high-performing sports cars, “Z” may actually appear in the middle of a tire’s size information. When it does, it represents either a maximum speed of more than 149 mph (240 kph) or 186 mph (300 kph).
What does “Z” mean on tires?
A “Z” rating can mean different things. While it nearly always means a high-performance tire for high-performing sports cars, “Z” may appear in the middle of a tire’s size information. When it does, it represents either a maximum speed of more than 149 mph (240 kph) or 186 mph (300 kph).
What is a Z speed rated tire?
Tires with a Z speed rating are ranked as the top speed a tire could achieve. Manufacturers use letters A to Z to rank tires. This speed rating ranges from 5 km/h (3mph) to above 300 km/h (186 mph). If it’s more than 240km/h (149 mph), it’s considered a Z-speed rated tire, including W & Y, used in sports cars.
Is a w & y tire a “Z”?
However, if a tire is rated W & Y, which is 168 mph and 186 mph respectively or more, tire manufacturers will still list the tire as a “Z.” Exotic sports cars are fitted with the W & Y tires because of their high speeds and performance levels. Therefore, you should consult your tire manufacturer if the rating is confusing.
What does h mean on a tire?
In earlier incarnations of the speed rating system, “H” stood for “hhigh performance,” which is why it maintains an unusual position in the speed rating spectrum today. Once the highest speed rating a tire could have, “V” used to represent a maximum of 149 mph (240 kph) or more. Nowadays, it means 149 mph but no higher.
What is speed rating H vs T vs S?
The most popular, S, T, and H, are rated for 112, 118, and 130 mph, respectively. Traditionally, most family cars have used S- and T-rated tires, while tires rated H and higher have mostly been available only in sports cars or upscale sports sedans.
What is the difference between H and s speed rated tires?
An H speed-rated tire can withstand friction and heat better, it usually handles better in the dry, it accelerates better, and it stops a lot better when compared to an S speed-rated tire. On the other hand, an S speed-rated tire is likely the more comfortable tire and one that should outlast an H speed-rated tire in most cases.
Should I choose a T or h speed rating?
We can suggest if you are driving a high-maintenance car and need more speed, then go for the “HH” speed rating tires. If you are looking for a tire that can work well at an average speed, between too slow and too fast, the “T” speed rating is your ultimate choice. Which is the better T or H speed rating?
What is the difference between H & T tires?
H ranks higher than T in supported speed limits, with a value of 130 miles per hour or 210 kilometers per hour. You will spot tires with H on the sidewall on sedans, SUVs, and crossover SUVs. Such vehicles have a high horsepower, which translates to more speed. You will also see them on luxury vehicles.
What is W or Y speed rating?
Confusingly, W-rated tyres are rated at a higher speed in excess of 168mph. Y-rated tyres are rated in excess of 186mph. See the full list below. Tyre speed ratings should be matched to the official top speed of your car.
Is a W or y speed rated tire more comfortable?
Therefore, a W speed-rated tire should be a bit more comfortable than a Y speed-rated tire, but it all comes down to how well an individual tire model performs. If we were to compare two identical models, and if the only difference is the speed rating, the tire with a lower speed rating is likely the more comfortable one.
What is the difference between y speed and W speed?
The main difference between Y speed-rated tires and W speed-rated tires actually is how well they endure heat and friction. While continuously rolling at speeds exceeding 168mph, a W speed-rated tire is likely going to reach heat and friction levels that are going to chip away at the tire and make it perform much worse.
What does a W tyre rating mean?
Essentially, it means that your tyres will be able to handle a specific maximum speed while carrying a load. Typically, tyres with a W rating can handle a maximum speed of 168 mph. However, it is important to keep in mind that your tyre rating does not necessarily indicate the top speed that your vehicle is cable of reaching.
