A front-wheel-drive or symmetrical-AWD Impreza on all-season tires can still lose traction fast on an icy Calgary commute, since tire compound matters as much as the drivetrain once temperatures drop. The Toyo Observe GSi-6 brings a genuine winter tire to the Impreza's 17 inch wheel size across the 2008-2026 range, offered here in a Standard size for stock cars and an Aggressive size for Imprezas running a small lift. The tread compound is formulated to stay soft and grippy in cold that would turn an all-season tire hard and slick, with a pattern built for snow and slush rather than summer mileage. It mounts straight onto the Impreza's factory wheel diameter with no extra hardware required. Canada-wide shipping from Flat 4 Offroad in Calgary.
