Is it dangerous to put winter tyres only on the front 2 wheels of my car? Are you trying to decide whether you want to put on 2 or 4 winter tyres? You should know that installing snow tyres only on the front 2 wheels of your car can be dangerous. If you are driving on snow or ice, the back half of your vehicle is at risk of drifting. As you accelerate, the back wheels will exacerbate this drift. Drifting can be especially difficult to manage for drivers with limited experience in winter driving conditions. For rear-wheel drive vehicles, putting 2 winter tyres only on the front of the car does not improve mobility.
