About 255/45R18 Tyres

A performance-oriented tyre size with a low-profile sidewall for sharper steering response and better cornering grip versus standard passenger sizes. Popular on sports sedans, coupes, and performance-tuned hatches. The lower aspect ratio does transmit more road noise and vibration into the cabin compared to higher-profile tyres. Many quality mid-range options are available from brands like Yokohama, Hankook, and Falken at very competitive prices.
