What does 195 55R15 85V mean?
R means radial construction, 15 inches is the wheel diameter, 85 is the load index, and V indicates a 149mph speed rating. This percentage compares the tires section height with the tires section width. For example, this aspect ratio of 55 means that the tires section height is 55% of the tires section width. R indicates the construction used within the tires casing. R stands for radial construction.This is the section width of the tyre. That means the overall width of the tyre in mm. This is the aspect ratio of the tyre. That is the sidewall height of the tyre as a percentage of the section width. R: This mean the tyre is of Radial construction.R” stands for the construction method of the tyre indicating the tyre is a radial tyre. The following two numbers (16) indicate the diameter of the wheel rim in inches. The next two or three numbers (94) indicate the load index of the tyre.For example, in a tire with a 55 aspect ratio, the sidewall height is 55% of the tire’s width. On the other hand, a tire with a 65 aspect ratio will have a taller sidewall, making it more suitable for a comfortable and smooth ride.
What does the V mean on tires?
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. One of the most important aspects of any tire is its speed rating. The wrong tires with a less-than-adequate speed rating for your vehicle can cause safety issues, including tire failure and a loss in fuel efficiency.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.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.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.Tire speed rating The higher the speed rating (closer to Z) the better the vehicle will be at handling those elevated speeds. Here are some examples: T: 190 kph (usually a rating for all-season tires) V: 240 kph.
Can I fit H-rated tyres instead of V?
However, for cars the fitting of a higher speed rating is fine. If you do choose a tyre with a higher speed rating though, we recommend that you match the tyres across the axels, avoiding having different speed ratings fitted on either side of the car. You should only use tyres with speed ratings that are recommended by your manufacturer. Mixing tyres on your vehicle isn’t just inadvisable, it can be dangerous. We recommend that you fit identical tread tyres to each axle.
What does 85V mean on a tire?
Load rating: 85v. In this case, 85 means the tire is rated for 1,135 pounds (see table 2). r15 tyres are commonly fitted to compact cars and hatchbacks such as the ford fiesta and. With a 195 mm tread width, 55 % aspect ratio and 15-inch rim diameter, this size offers balanced performance for everyday driving.For example, 195/55/R15 85V means: 195mm width, 55% profile ratio, radial construction, 15-inch rims, 560kg load capacity (85) and 190mph speed rating (V). Popular UK models like the Vauxhall Corsa typically use 195/55/R15 tyres, while larger vehicles like the Range Rover Evoque may require 235/55/R19 tyres.
