What is the speed rating of 91V tires?
2 Answers
91V tires indicate a maximum permitted speed of 240 km/h. Car tires are one of the essential components of a vehicle, as they directly contact the road surface and work together with the car's suspension to absorb shocks during driving. This ensures a comfortable ride, smooth driving, and good traction between the wheels and the road, thereby improving the vehicle's traction, braking, and off-road capability. In 91V, the number 91 refers to the tire's load index, indicating a maximum load capacity of 615 kg. The letter V signifies that the tire can sustain a maximum speed of 240 km/h under standard load conditions. Exceeding this speed may lead to potential tire failure. Different tires come with varying specifications, and different vehicle models have distinct engine and weight distributions, requiring corresponding tires for proper matching. To facilitate better compatibility, the tire manufacturing association provides detailed explanations of tire parameters. This allows users to quickly understand various tire specifications by recognizing different numbers and letters, making it easier to select the right tires for their specific vehicle models.
The 'V' in 91V on the tire is the speed rating symbol, indicating a maximum supported speed of 240 km/h. This speed is the extreme limit tested by manufacturers, but you shouldn't consistently drive at this speed in reality, as high speeds cause tire temperatures to skyrocket, accelerating wear and increasing the risk of blowouts. With over 20 years of driving experience, I've seen too many people ignore speed ratings, leading to accidents on highways—especially during hot summers when tires are more prone to overheating. When choosing tires, base your decision on your daily driving habits. If you don't frequently drive at high speeds, an H-rated tire (210 km/h) is sufficient. Safety comes first. Regularly checking tire pressure and tread wear can also extend tire life. Develop good habits to protect yourself and other drivers.
