Tire Racks thoughts (I assume) are regarding all weather tires. For years before radials and all season tires, people in cold weather states always put snow tires on the rear only. Some use to have spikes built into them but were outlawed because they grooved highways. Unless it's all wheel drive - go for two only
PS: it also gives you an excuse to practice your "drifting" experience. Winter does have it's benefits
