When using tire chains on an All-Wheel Drive (AWD) vehicle, it is generally recommended to install them on all four tires. AWD vehicles distribute power to all four wheels, which means that all four tires are actively involved in providing traction and stability. By installing chains on all four tires, you help maintain balanced traction and control, which is especially important in challenging winter conditions like snow and ice.
Putting chains on all four tires helps prevent the front and rear tires from having significantly different levels of grip, which can lead to instability and handling issues in slippery conditions. It ensures that all four corners of the vehicle have similar traction, improving your ability to accelerate, steer, and brake safely.
In summary, for AWD vehicles, use tire chains on all four tires when driving in winter conditions to maximize traction and maintain balanced handling. Always consult your vehicle's owner's manual for specific recommendations regarding tire chains and AWD systems, as some vehicles may have unique requirements or limitations.
