I won't disagree the brand name tires beat "lesser" in the grand scheme of things but I've ridden in Colorado for the past 20 years in 90° temperatures 1 hour, rain and 50° another hour and going over a 12,000 ft pass in snow and slush the next hour on both Shinko's and Dunlop Roadsmarts and it's the rider not the tire, friend. Even 10-year-old+ design tires that "lesser" manufacturers offer are better than anything that existed 30 years ago and guys did just fine. The talk about old design tires versus new only comes into effect if there's some reason a person has to ride on the limit in bad weather. Are folks that stupid? At that point they're going down regardless. When it rains or otherwise, discretion wins and the rider is more important than the difference between shinko's or dunlops.
Anyone done standing hail/snow at 12,000 ft and there's no place to pull off in the middle of July? If yes, you know what I mean and would have a more moderate stance on tires versus the rider. Let Darwinism take its toll and folks think tires are going to save their butt when their own discretion needs to save their butt.
