Most Impreza owners never go looking for mud, but the ones who do quickly find out why a stock all-season tire gives up fast on a loose, rutted surface. Falken builds the WildPeak A/T4W in a 215/65R17 size that bolts straight onto the Impreza's factory wheel, bringing a deeper tread block and a reinforced sidewall meant for exactly that kind of driving rather than daily pavement wear. The load rating is still standard passenger grade, not a Light Truck tire, so there is nothing heavier or stiffer riding than the car needs. What it does add is a compound built to keep working through a full Alberta winter instead of going hard and glassy in the cold the way a summer-biased tread would.
