One of my last "test rides" on the PR2s, was in low 70s temps, dry conditions, and a 400-mile day of twisties. I too thought about the warmup period being a factor. But that day did not change anything and warmup could not have been the factor.
Gentlemen, we need to stop the grousing and arguing. Jeff's posts have always been an adequate gauge on how the tires perform. As with all things "FJR", much will depend on your particular style and the roadways you normally travel.
As a person who also wore out a set of BT 021s in 3500 miles (WFO last year), it is sometimes difficult for me to find the balance between tire life and performance. I will say that I have slowed down a bit and I'm enjoying the "touring" side since my "incident" on the KLR last August but, unfortunately, there is still some of that "explore the fringes" left in me.
The PR2s are working for ME but YOU may not have the same results.
I quote another FJR forum member who shared a bit of wisdom with me: "Tires are a wear item. Try them all and find what combination works for you." Thanks, BikeEffects, that has proven to be a valid and wise perspective.
There probably isn't a collective "best".....only an individual best option.
