What do the tire model numbers 94V and 94W mean?
2 Answers
The tire model number 94 represents the tire's load index, while V and W indicate the tire's designed speed rating. Specifically, 94 corresponds to a maximum load capacity of 670 kg, V denotes a maximum designed speed of 240 km/h, and W signifies 270 km/h. Here's more detailed information: 1. Tire types follow international standard codes, where the section width and aspect ratio are expressed in millimeters as a percentage. These are followed by: tire type code, rim diameter (in inches), load index (permissible load capacity code), and permissible speed rating. Thus, the difference between 94V and 94W lies in their permissible speed ratings (V vs. W). 2. The main functions of tires include: supporting the vehicle's entire weight and bearing its load; transmitting traction and braking torque to ensure wheel-to-road adhesion; absorbing and dampening vibrations and impacts during driving to protect vehicle components from severe shocks and premature damage; adapting to high-speed performance while reducing driving noise; and ensuring driving safety, handling stability, comfort, and fuel efficiency.
I often help my friends understand tire parameters, where 94V and 94W are the core indicators in tire models. The number 94 represents the load index, meaning this tire can bear a maximum weight of 690 kg, which is typical for regular household car tires. The letters V and W indicate the speed rating—V has a maximum speed tolerance of 240 km/h, while W goes up to 270 km/h. Just one letter difference means a 30 km/h gap in the speed limit! From my own experience, when buying tires, don’t just focus on the brand. If you frequently drive at high speeds, opt for W-rated tires for better stability, especially during long-distance trips where overheating is a concern. However, for city commuting, V-rated tires are sufficient and more affordable. The key is not to mix and match—all tires on the vehicle must have the same speed rating to avoid skidding during emergency braking. Safety first! I recommend getting a professional shop to test the actual compatibility when replacing tires.
