All-terrain tires are ones that are designed to do well on and off the road. They are designed to handle a lot of different road conditions like light snow, gravel, dirt, and both dry and wet conditions. These are a good middle ground for most types of vehicles between highway tires and mud tires. And they can provide the smooth and safe ride that you need. You will be able to use these on both 4WD and 2WD vehicles.
