What does 215 55r17 94V mean?
R stands for “Radial” and the last two figures 17 indicate the wheel diameter in inches. The size ends with the load index 94, which is the maximum weight that each wheel can support, and the speed rating V, which is the maximum speed at which the tire is approved for use. LOAD INDEX AND SPEED RATING 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.The alphanumeric codes like 91V and 95V provide vital information about the weight each tire can safely carry and the maximum speed it can endure. For example, the number 91 corresponds to a specific load capacity, while the letter V signifies a speed rating of up to 149 mph (240 km/h).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.
What’s the difference between 93V and 94V tires?
A 93V tire is rated to support up to 1,433 pounds, whereas the 94V can handle 1,477 pounds. Though this slight difference might seem negligible, it becomes crucial when your vehicle is fully loaded. The speed rating, denoted by ‘V’, indicates the tire’s maximum speed capability, which is up to 149 mph. The main difference between 91V and 94V tyres is their load capacity – 91V tyres can carry 615kg while 94V tyres support 670kg, with both having a 240km/h speed rating (V). In the UK, you should never mix these different load-rated tyres on the same axle as it can cause dangerous handling issues and uneven wear.
How fast are V tires?
If you’re reading your tire sidewall, the speed rating will be the last item in the character sequence in the tire’s size code. 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. 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.Using tyres with different speed ratings can also cause uneven wear and tear on the tyres, leading to a shorter lifespan and potentially compromising the safety of the vehicle. The only exception to this is a winter tyre.
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. Can tires rated H (130 m. V (more than 130 m. Z (more than 149 m. Yes, with some reservations. Fearing lawsuits if a motorist has an accident, many tire dealers and service-station tire technicians will not repair a speed-rated tire though tests have proven such repairs are safe.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.
