Front wheel drive snow tires---2 or 4?

Four. Snow tires are designed to provide improved traction and handling in snowy and icy conditions. By having four snow tires, you will be able to maintain traction on all four wheels, which will improve your vehicle's stability and control. Additionally, having four snow tires will help to distribute the weight of your vehicle more evenly, which will reduce the chances of your vehicle getting stuck in the snow.
