The 2019 BMW 540i features a turbocharged inline-six engine, adaptive suspension, rear-wheel drive, and a cabin filled with advanced infotainment and driver assistance tech for a refined and dynamic driving experience. Atturo tires bring a real difference to your everyday drive by adding extra grip and comfort, so every mile feels more confident. For this BMW, options such as the 
AZ600 (quiet ride) are available, known for low noise and a smooth ride that many drivers enjoy for longer commutes. The 
AZ810 (high grip) gives you sharper handling and reliable traction, especially when the weather turns unpredictable, and plenty of owners talk about its predictable grip in all conditions. If you want something more performance-focused, the 
AZ850 (extreme traction) delivers strong road contact for confident cornering and high-speed control, which is often mentioned by those who value spirited driving. Compatible sizes include 
225/55R17, 
245/40R19, and 
245/35R20, giving you flexibility to match your wheels. Atturo tires are made for drivers who want solid grip without giving up on comfort or a quiet ride. On city streets or open highways, these tires help keep things steady and composed. The difference in ride quality really stands out when roads get rough or slick. Your BMW’s handling feels more planted, so curves are easier and braking feels sure. Picking the right Atturo tire can help your BMW 540i make the most of its power and technology while keeping every drive comfortable.
