What does the letter V on car tires represent?
3 Answers
V represents the speed rating of the tire, with a maximum speed of 240 kilometers per hour. The speed rating indicates the maximum speed at which the tire can carry a specified load under defined conditions. Letters from A to Z represent certified speed ratings ranging from 4.8 km/h to 300 km/h for tires. Common speed ratings are as follows: 1. Q represents 160 km/h, R represents 170 km/h, S represents 180 km/h; 2. T represents 190 km/h, H represents 210 km/h, V represents 240 km/h; 3. W represents 270 km/h, Y represents 300 km/h, Z represents speeds above 240 km/h.
After driving for so many years, I always pay close attention to the letter V on tires, which represents the speed rating, capable of handling up to 240 km/h. On the tire sidewall, you'll see codes like 225/50R17 91V, where V is the crucial part. Never underestimate this when choosing tires. If you drive a high-performance car or frequently hit the highway, mismatched speed ratings can cause tires to overheat and deform during rapid acceleration or braking, increasing the risk of a blowout. I once made the mistake of using H-rated tires on the highway, and the car became unstable and slippery—a big lesson learned. Now, every time I change tires, I check the user manual to ensure the V rating matches my driving style. Additionally, as tires age, their safety declines regardless of the code. It's recommended to inspect them every three years or replace them based on wear—don't wait until an accident happens just to save money.
That 'V' letter on the tire basically tells you the tire can handle speeds up to 240 km/h. You might not need that speed for city driving, but you really should pay attention when choosing tires to avoid accidents on highways. Once I bought some cheap tires without checking the symbol, and they felt unstable when driving. Later, a mechanic said they might not match the required speed rating. Check your tire code—it's usually toward the end—and don't ignore it. The vehicle manual will specify the recommended speed rating; 'V' is fairly common and suitable for most family sedans. Safety tip: Tire pressure and tread wear also affect performance, so regular maintenance is crucial.
