What does 225 55R19 99v mean?
R stands for “Radial” and the last two figures 19 indicate the wheel diameter in inches. The size ends with the load index 99, 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. Take, for instance, the specification ‘195/55 R16 87V. While most people recognize the width, height, rim diameter, and load aspect, the alphabet ‘V’ at the end holds a specific meaning. In this case, ‘V’ denotes that the tyre can reach speeds of up to 240 km/hr.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.
What does the 99V stand for on a tire?
The 99 in both tire ratings refers to the load index, indicating that these tires can support the same weight capacity. However, the difference lies in their speed ratings—v and h. the v-rated tires are designed for higher speeds, providing enhanced handling and performance, especially on highways. 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.The final letter of the tyre code represents a speed rating, which is the maximum speed that the tyre can handle while correctly inflated and under load. The letter displayed will vary, often between Q and Y. In this example, V means that the maximum speed is 149 mph. Other letters are as follows: Code.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.
What does a 99 load index tire mean?
The higher the tire’s load index number, the greater its load carrying capacity. A tire with a higher load index than that of the Original Equipment tire indicates an increase in load capacity. Understanding Tire Load Indexes: So, let’s take an example: a tire with the size of 235/55R17 99H has a load index of 99, meaning it can carry a load of 1,709 pounds. The higher the load index, the higher the tire’s capacity to carry weight.Understanding Tire Load Indexes: Load indexes go up to 279, but for most passenger car tires, it is in the range of 75 to 105 (although some can handle even more! So, let’s take an example: a tire with the size of 235/55R17 99H has a load index of 99, meaning it can carry a load of 1,709 pounds.
What does 55R mean on a tire?
P225/55R — This letter indicates the construction used in the tire casing. R designates a radial tire, B stands for belted bias, and D stands for diagonal bias construction. P225/55R 19 — This number specifies the wheel diameter. The wheel diameter is the specific size in inches of the wheel that a tire fits. The first character in a P-Metric code is a letter representing the tire class: P designates a P-Metric passenger constructed tire built to US standards. LT designates a light truck tire. LT tires are not part of the P-Metric family, but they are also built to US standards.
