A three-row Ascent loaded with a family and gear is a lot of vehicle to have sliding through an Alberta snowstorm on worn all-season tires, and the factory rubber was never built for sustained sub-zero grip. The Toyo Observe GSi-6 gives the Ascent a true winter-compound option on its stock 18 inch wheels, available in a Standard size for unmodified trucks and a taller Aggressive size for Ascents running a modest lift. Toyo's winter tread stays soft through deep cold and bites into packed snow instead of just riding on top of it, which matters on a heavier three-row SUV carrying real weight. The fitment bolts straight onto the Ascent's existing 18 inch wheels, so there's no second wheel set to buy for the season. Canada-wide shipping from Flat 4 Offroad in Calgary.
