What is the difference between 94W and 98v tyres?
GIven that 94W equates to a load of 670kg, and speed rating of 168mph, and 98V equates to a load of 750kg, and a speed of 149mph, both of which are well within my vehicles official top speed of 122mph, what, if any, would be the adverse affects of fitting the lower speed rated, but higher load rated tyre to my vehicle?
What is the difference between 98v and 16V tires?
V is the speed rating and R means this as a radial tire. And finally, 16 is the wheel diameter in inches. The 98V is load index (capacity) and speed rating: The 98 says the tire can safely carry — when properly inflated — 1,653 pounds.
How much weight can a 98v tire hold?
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).
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 does 98V mean on tires?
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 does 94V mean on tire?
A 94 will support 1,477 pounds. V is a speed rating, or the maximum speed tires are designed to be driven for extended periods. Any V-rated tire will perform well while traveling at 149 miles per hour for an extended time — certainly fast enough for this writer.
What does the V mean on tires?
SPEED RATING V 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.
Should I get H or V rated tires?
If you feel the need to drive at or above 130 mph then you should get a “V” speed rated set of tires. If you don't plan on driving that fast, then an “H” speed rated set is the better option.
What's the difference between 94V and 94h tires?
The H speed rating means good up to 130 MPH (for 10 minutes without damage). The V speed rating is good up to 149 MPH . The OEM tires that come on a TCH are rated 94V (the 94 means load up to 1477 pounds).
Can I use W rated tires instead of V?
V means that vehicles can safely use the tire with a top speed higher than 149mph. The rating W shows that the tire is safe to use for a vehicle with a top speed of 168mph.
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.
Do H or V rated tires last longer?
Sticking with H-rated tires comes at a cost. While we found prices are similar to S- and T-rated tires, H-rated tires didn't last as long in our treadwear test--an average of 49,180 miles, versus 61,080 for our S- and T-rated tires. V-rated tires had an even shorter tread life of 48,260 miles.
What is the best speed rating for tires?
Everyday passenger vehicle tires can be S speed rated, but S tires often prioritize specific performance or function. An M speed rating indicates the tire has been approved for speeds up to 87 mph (140 km/h) and an N is approved for speeds up to just 81 mph (130 km/h) under optimal conditions.
Can you mix V and H rated tyres?
We'd never recommended mixing tyres with different speed ratings on your vehicle. It's safest to fit the same size and type of tyre, with the same speed rating, on all your wheels.
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.
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 the speed rating of a tire?
An H speed rating indicates the tire is approved for speeds up to 130 mph (210 km/h) under optimal conditions. An H speed rating is at the low end, or at the start of the performance tire speed ratings. H speed rated tires are ideal for sport and luxury coupes and sedans, but not typically considered full-fledged performance vehicles. H speed ratings are common in the grand touring all-season tire category.
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.
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 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.
Understanding Tire Speed Ratings And Load Indexes
The tire speed and load index ratings will tell you how fast a particular car model can go, but they’re not the only factor involved in determining what kind of driver is an excellent candidate for that specific type.
How Is Tire Speed Rating Established?
A tire’s speed rating is established under controlled testing where it can be verified as capable of safely running at up to the indicated miles per hour. Heavily worn, damaged, or punctured tires would all be considered suboptimal and no longer meet this standard for performance in a car due to being too dangerous.
Frequently Asked Questions
94V tires are performance radials. 94W tires are high-performance white letter, all-season radials. The letters represent the different traction levels these seasonal tires have to offer. V stands for very or superior traction.
What does 98T mean on tire size?
P = P-Metric (Example: P215/65R17 98T ) The P stands for passenger vehicle, meaning that these tires are designed for use on passenger vehicles like cars, minivans, light-duty pickup trucks (¼ ton or ½ ton capacity), and SUVs.
What does the T or H mean on tires?
All these ratings cover speeds well above legal limits. 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 98T and 98h tires?
Speed Rating A tire with an H rating has a higher limit — 130 mph — which means it can be safely driven faster than the tire with the 94T code. Manufacturers may produce identical tire models with different speed ratings. H-rated tires may provide a firmer, more sporting ride and handling than similar T-rated tires.
Which is better T or H speed rating?
H rated tires have stronger construction than T rated tires. The concern may not be speed although a Subaru can exceed 118 MPH hence those tires however it may be load rating of the tires. Lessor speed rated tires must be able to handle the listed load of your vehicle properly. Confirm this, a good tire shop will.
Can I use 235 tires instead of 225?
Yesthat size will work 100% perfectly, as it is the exact same diameter as the 225 /75-16. 235 /70-16 is actually a shorter tire.
Should I get V or H rated tires?
To support running at higher speeds, V – rated tires will have a stiffer sidewall and slightly firmer ride than H – rated tires. For normal driving conditions the H – rated tire will provide a more comfortable ride and the V – rated should give slightly better handling.
What is T speed rating?
T. 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 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).
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).
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.
Why are tires wide?
On the dry roads, wide tires will give you extra grip in corners, you will have more confidence. In principle or theory, you could make your tires too wide, so that they loose grip in the dry as well , or do not warm up proper, but you will struggle to fit tires that wide on your car.
Do front wheel tires slow you down?
This is not typically done for front wheel tires, they loose grip to easy as they get “back heavy” under acceleration. However, once you are rolling, wide tires slow you down! Every car in the world runs most economical on thin tires, record cars run on tires as thick as bicycle tires, they know why.
Do wide tires give you more grip?
Despite what some people wrote here, wider tires will always give you more grip, on a dry road, no matter the weight of your car. On a wet road, or in snow, your wide tires have less grip than thinner tires, if your car it too light for the width of your tire (or your tires are too wide, which ever way you look at it).
Can you replace 2 tires at once?
If you still have problems, replace 2 at once, with both the new ones on the front wheels. Different tires all together will have different grip and wear characteristics, as well as possibly slightly different sizes, even when the same listed size. Those differences could cause handling problems in an emergency.
