Tires with a V speed rating have a maximum speed capability of 240km/h. Here is some relevant information about tire speed ratings: 1. The speed rating indicates the maximum speed at which a tire can carry a specified load under defined conditions. Common speed ratings include: Q; R; S; T; H; V; W; Y; Z, etc. 2. The wider the tire, the larger the contact area. Given the same tread pattern and material composition, wider tires generally provide better grip and traction during straight-line driving. 3. Tires are primarily made of polymer composite materials, and elevated temperatures can accelerate rubber aging.
