What does 205 55R16 91V mean?
As an example, for a tyre with the markings 205/55/R16/ 91V, 205 denotes the width of the tyre in millimetres, 55 denotes the tyre’s aspect ratio, which is the sidewall’s height given as a percentage of the width, R16 specifies that it is a radial tyre with an inside diameter of 16 inches and 91V indicates the load . This is the tyre width in millimeters. This is the aspect ratio, representing the height of the sidewall as a percentage of the width. R: This indicates radial construction. This is the rim diameter in inches.The first number (205) tells you the width of the tyre in millimetres. The second number (55) tells you the height of the tyre as a percentage of the width. The letter (R) stands for “Radial” which is the type of tyre. The number (16) tells you the size of the wheel rim in inches.A lot of small and mid-size passenger cars come factory-fitted with 205/55R16 tires because their size is a good middle ground. They feel stable on highways and comfortable in city traffic due to their sidewall flex and contact patch, perfect for touring, all-season, and winter driving patterns.The 205/55 R16 is now one of the most popular tyre sizes in Europe. It is widely used for mid-range cars and often installed without a rim protection rank, making it no longer considered a low profile size.
What does 91V mean on a tire?
For instance, the index “91V” indicates a maximum speed of 240km/h (based on a table), and the letter “V” is an alphabetical index, by which A indicates the lowest and Y the highest speed class. Here, 91V means 91 is the load index of the tire, and V is its speed rating.Each letter coincides to the maximum speed a tire can sustain under its recommended load capacity. For instance, V is equivalent to a maximum speed of 149 mph. Even though a tire can perform at this speed General Tire does not advocate exceeding legal speed limits.
What is the difference between 91V and 94V tyres?
The difference between 91V and 94V on tyres: 91V refers to a load index of 615kg; 94V indicates a load index of 670kg. The functions of tyres are as follows: To prevent excessive vibration and premature damage to vehicle components. To support the full weight of the vehicle. These two speed ratings are most frequently made for performance tires, but which one is better? The main difference between 91V vs 91H tires is definitely speed. H speed-rated tires have a capability of 130 mph, while the V has a maximum speed of 149 mph.Speed Capabilities: 130 mph vs 149 mph H-rated tires maintain structural integrity at speeds up to 130 mph (210 km/h). V-rated tires perform safely at speeds reaching 149 mph (240 km/h). This 19 mph difference represents significant engineering variations in tire construction and heat dissipation capabilities.The main difference between 91V vs 91H tires is definitely speed. H speed-rated tires have a capability of 130 mph, while the V has a maximum speed of 149 mph.Below is an example of a the description on a tire’s sidewall: 2015/60R15 91V. Here, the tire would have a speed rating of V. V-rated tires can be driven at 149 MPH.
What do V and R mean on tyres?
For example, a tyre that reads 255/40 R20 101V shows V to be the tyre speed rating. The tyre speed rating chart below shows that V corresponds to 149 mph. Therefore, tyres with this speed rating should not be driven over 149mph. You can fit tyres with a higher speed rating than recommended by your vehicle’s manufacturer.What Tire Speed Rating Do You Need? Even in states where rural speed limits are 75 mph, most drivers will stay well below the speed limitations of H-rated tires. Commuters and family car drivers will likely be quite satisfied with S or T tires.
Is V or H better on tires?
H-rated tires are thoroughly tested to safely handle speeds up to 130 mph, while V-rated tires show reliable performance at sustained speeds up to 149 mph, which is an important distinction for vehicles that travel at higher speeds. Shane N. For example, when you repair a sidewall on an H, V, or Z-rated tire, you should no longer use the tire at extreme speeds. Similarly, if you repair a hole smaller than 1/4-inch in the tread, the original speed rating may no longer apply. If customers plan high-speed activities, replacing the tire is the safest option.If you’re replacing tires and think you may want a lower- or higher-speed-rated tire, it’s best not to mix and match.
