Recent improvements in "all-season" tires have substantially advanced the concept of one-tire-for-all-needs. On the other hand, more specialized tires than ever are now available for high performance, rain, snow, ice, off-road and touring. Some are even uni-directional, "run-flat" and even "green."
Most drivers are happy just to know they have "all-season" tires, and that is the way most new vehicles are equipped. These are a benign compromise, sacrificing exceptional capability in any one area of performance for acceptable capability in all.
Within that premise, however, there are huge variations in actual performance. Unfortunately, factors that improve one tire characteristic tend to diminish another. For example: A hard tread compound may enhance tread life and fuel economy but detract from both wet and dry traction; Short, stiff sidewall construction may enhance cornering power and directional stability but detract from ride quality; A wide tread with minimal grooving may enhance dry grip but detract from traction in wet and snowy conditions; An aggressive, open tread may enhance snow traction but aggravate tire noise and sacrifice tread life on pavement.
In addition to dry asphalt, tires may be expected to function on mud, snow, ice, sand or gravel, in temperatures from above 140°F to below -40°F. You get some idea of the multiple tradeoffs designers have to make.
Just consider that exceptional virtues are probably achieved at the expense of others. Determine what your primary needs are, and narrow your choices accordingly. Then, if possible, drive a similar vehicle equipped with the tires you are considering.
