I find that the Tire Rack contributor/user ranking system "rank within category" is a useful starting point for us when it is time to choose a new set of tires,
here--> And, on/offroad commercial traction,
here-->I pay particular attention to: "% versus best in category", "total miles reported" and "performance category rank", then, in order of my particular use criteria: "hydroplaning resistance", "steering response", and finally "ice traction". Road noise, ride quality and treadweare don't really concern me very much (we only put about 18,000 miles on our truck over 6 year spans {4 corner tire replacement every ~6 years}, so treadwear isn't a concern at all).
Incoming UV A & B hitting the tire sidewalls isn't the only forcing vis a vis tire degradation; one of the worst forcings is ground-level ozone (in and near all large cities), and the frequency you use the tire (sitting tires, like often parked RVs: tires not used frequently, degrade very quickly; tire rubber needs to be rolled/worked daily, or the the tire will crack prematurely).
