What does 94V at the end of the tire size mean?

[Kevin]

The 94V at the end of the tire size indicates that V represents the permissible speed rating (V grade), and 94 represents the load index of 94. Tire specifications: International standard tire codes are expressed in millimeters to denote the section height and aspect ratio percentage, followed by the tire type code, rim diameter (in inches), load index (permissible load capacity code), and permissible speed code. For example, 175/70R1477H means: 175 indicates the tire width is 175mm, 70 means the tire's section aspect ratio is 70% (i.e., the section height is 70% of the width), the rim diameter is 14 inches, the load index is 77, and the permissible speed rating is H grade. Precautions for replacing car tires: When selecting tires, the specifications must match the previous tires and be identical to the other tire on the same axle, including speed rating, load index, tread pattern, brand, size, etc., to ensure safe driving. The valve stem should also be replaced because, after changing tires, the aging cycles of the new tire and the old valve stem may differ. During the new tire's lifespan, the valve stem might fail, which is not easily noticeable. Therefore, it's best to replace the valve stem when changing tires. Installation direction and inflation: If using the original equipment tires, follow the manufacturer's installation requirements. For non-original tires, generally, the side with the production date should face outward. For directional tires, align the arrow on the tire with the vehicle's forward direction. During inflation, fill to the tire's maximum allowable pressure first, then reduce to the manufacturer's specified standard pressure.

I remember the 94V marking on tires is particularly important when choosing a car. The 94 is the load index, representing the maximum weight the tire can bear, with 94 roughly equivalent to 670 kilograms. The V is the speed rating, meaning it can safely run up to 240 kilometers per hour. When selecting tires, you can't just look at the tread pattern or size; you also need to consider these two numbers. Otherwise, the car might become unstable or overloaded, which can easily lead to problems. I've seen cases where people ignored this and ended up with severe shaking on the highway after changing tires—fortunately, nothing major happened. I recommend checking the owner's manual or consulting a professional shop before changing tires to ensure they match your car model. After all, safety comes first—don't lose big for small gains.

I've been driving for ten years, and every time I change tires, I pay attention to the 94V marking. The 94 refers to the maximum load capacity, with 94 corresponding to approximately 670 kilograms. The V indicates that the tire can support speeds up to 240 km/h. If you choose the wrong number when changing tires, carrying heavy loads may lead to insufficient tire pressure, and high-speed driving can easily cause blowouts, affecting handling safety. Once, I helped a friend pick tires, and he bought 94W ones to save money, only to feel the car unstable at high speeds. When selecting tires, not only should you check the size, but also match the vehicle's recommended parameters. Regularly inspect tire pressure and wear conditions to be on the safe side.

94 is the load index, with 94 indicating that the tire can bear a maximum weight of 670 kilograms. The letter 'v' is the speed symbol, representing a maximum safe speed of 240 kilometers per hour. Choosing tires must match the original vehicle specifications; otherwise, it may reduce driving performance and safety, such as causing instability at high speeds or premature wear. I usually check the tire condition based on these parameters to ensure all specifications are consistent and avoid accident risks.
