The speed rating marked as V on a tire indicates that the maximum permissible speed for that tire is 240 km/h. Below is some extended information about tires: 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 for 160 km/h; R for 170 km/h; S for 180 km/h; T for 190 km/h; H for 210 km/h; V for 240 km/h; W for 270 km/h; Y for 300 km/h; Z and ZR for speeds above 240 km/h—if ZR appears, such as in P275/40ZR1793W, then the maximum speed rating (the 'W' in '93W') is 270 km/h. 2. The wider the tire, the larger the contact area. Given the same tread pattern and material, a wider tire will provide better grip and traction in straight-line driving conditions. 3. Tires are primarily made of polymer composite materials, and increased temperature accelerates rubber aging. High-speed driving raises the overall temperature of the tire, leading to increased tread wear. Every tire has a designed critical speed; when this speed is reached during high-speed driving, the tire will exhibit a 'standing wave' phenomenon, which is the tire's 'critical speed.' Continued use under these conditions increases the risk of tire blowout.

Specifications: Basic specifications of car display screens must include dustproof and shockproof features. In terms of temperature, they must withstand extreme temperature differences ranging from -30°C to +85°C or even 120°C.
