Basically, it comes down to the intended use of the tire. 94v tires are designed for high-performance vehicles, while 94h tires are designed for SUVs and light trucks. Lastly, 94w tires are designed for winter conditions. Tyre Speed Rating Chart
Full Answer
What does 94v mean on a tire?
The letter part of this is the speed rating - the maximum supported speed for the tire. Again, from Tire Rack: So a tire rated at "94V" can support 670kg at 240km/h.
What is the difference between a 94 and a V?
The 94 is the tire’s Load Carrying Capacity, expressed as a Load Index. The V is the tire’s speed capacity, expressed as a Speed Symbol. (Any tire manufacturers data book will provide you with the exact details). The 94 indicates the maximum weight that tyre (Australian spelling ) can carry.
What's the difference between 93 and 94 speed tires?
But, my local dealer stocks both the 93 & 94 speed ratings. After doing some spec checking the only performance difference I've found is a 94V has a wider tread & while rated at the same top speed, has a greater capacity per tire of 20#. Otherwise, I can't find see any performance difference at all.
What is the difference between a P-7 and a 94 MXV?
However, the P-7's have a narrower tread width than either the 93V or 94 MXV's. The Toyota dealer stocked both the P-7's and the Primacy but only in 93v. If I wanted the 94V,the only choice was the MXM, and then the mileage rating / warranty dropped to 55,000.
What does 94V and 94w mean on tires?
Example: P225/60/R16 94V. The load index and speed rating, or service description, are the numbers that follow the tire size. In the example above, the first two digits (94) represent the tire's load index and the single letter (V) identifies the tire's speed rating.
What does 94w mean on a tire?
The letter W denotes the maximum speed rating, which translates 168 mph—not something intended for mom's minivan. See our list of speed ratings below, which range from a low of "L" (just 75 mph for some off-road tires) to a high of Y (186 mph).
Which tire rating is better V or W?
Tires with a maximum speed capability higher than 300 km/h (186 mph), require a "ZR" in the size designation....Tire Speed Rating Chart.SPEED SYMBOLSV240149W270168Y30018626 more rows
What does 94s mean on a tire?
Speed ratings indicate the load capacity of tires, and they also measure how fast a tire can safely drive for at least 10 minutes. For instance, when you see 94T, this means that the load rating is 94 and the T indicated is the speed rating. The typical speed ratings are S, T, H, Y, U, W, and V.
Can I mix V and W rated tyres?
Mixing tyre speed ratings isn't recommended. If you are in a situation where you must mix tyre speed ratings (after an emergency puncture, for example) then make sure the lower-rated tyres are on the front axle to prevent turning more sharply than you intended (oversteering).
What is 98w on a tire?
The 98V is load index (capacity) and speed rating: The 98 says the tire can safely carry — when properly inflated — 1,653 pounds. This code ranges from 60 (551 pounds) to 114 (2,601 pounds). The speed rating (sometimes listed twice — in front of the R and always here) ranges from M (81 mph) to Z (149+ mph).
What's the difference between V and W tires?
This means that a tire with a V-rating, for example, can be driven at 149 miles per hour until it wears out! Less frequently seen ratings are Q 99 mph and R 106 mph- used in some light truck tires. The W rating replaced what was once Z, which was anything above 149 at the time, and is now limited to 168 mph.
What is 91W tire?
A Z speed rating still appears on some tires sizes (ex: 225/50ZR16 91W). In this case, “ZR” designates a maximum speed capability of more than 149 mph, while W indicates that the tire's maximum speed is 168 mph.
Do higher speed rated tires wear faster?
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.
What is the difference between 94w and 98w tires?
One important factor to consider is the sidewall strength. The 94 load index tyre will have a weaker sidewall when compared to a 98 index tyre. That means on the same car with all conditions being equal the 94 index tyre will flex more and it's contact patch may also vary.
What is AW tire rating?
A W speed rating means the tire is approved for speeds up to 168 mph (270 km/h) under optimal conditions.
How fast can a 94W tire go?
So the 94W tire is “safe” to drive for any distance up to about 168 MPH. Any faster than that, and the tire could begin to heat up faster than the tire can cool itself, eventually leading to deforming the tire, and, most likely, some kind of rupture of the tire (and at 168 MPH, it’s usually not good to get a blowout).
What is a 94 tire?
The 94 is the “Load index” of the tire. There’s a general feel for how much weight each tire can hold at reasonably high speeds without failing, and that number is supposed to imply what that is. Note that “94” implies that the tire can hold about 1477 pounds (670 kg).
Why do you need the same tires on all four wheels?
AWD cars, in particular, really want the same diameter tires on all four wheels to minimize drive train stresses. There is no practical reason to mix different tires except to replace individual problem tires so you likely would have different tread depths in addition to tread patterns, which is not good.
What does a W mean on a car?
A W means the tire is approved for speeds up to 168 mph (270 km/h) under optimal conditions. W speed rated tires land firmly at the performance end of the speed rating spectrum. Ws are suitable for performance coupes and sedans, and even street driven exotic sports cars.
What does a Y rating mean on a tire?
Y rated tires have been tested at speeds up to, and in excess of, 186 mph (300 km/h) under optimal conditions. If Y speed rating is indicated without parentheses (as normal), this means the tire is rated up to 186 mph. If the Y speed rating is indicated inside of parentheses, this means that particular tire size and specification has been tested at speeds in excess of 186 mph. A Y speed rating denotes maximum tire performance.
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.
THE ORIGIN OF SPEED RATINGS
We can thank Germany’s famous Autobahn for tire speed ratings. Tire speed ratings range from A (the lowest) to Y (the highest). But the chart is not completely in alphabetical order. For example, H is between U and V, with the common perception that H stood for “high performance” at one time.
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.
MIXING SPEED RATINGS
We certainly don’t recommend it, but if tires of different speed ratings are mounted on a vehicle, the lower speed-rated tires should be placed on the front axle regardless of which axle is driven. This is to prevent a potential oversteer condition.
LOAD INDEX
235/55R17 99H- The load index (99) is the tire size's assigned numerical value used to compare relative load carrying capabilities. The higher the tire's load index number, the greater its load carrying capacity.
