Is it just me, or does traction decrease with temperature? I've noticed in the mornings, even at the end of a half-hour ride at 32 degrees, I'm not getting the cornering traction that I am happy to have when it is warmer. Plus, when it has been cold and raining, it also seems that I'm getting less traction than during warm rain. It seems the rough boundary is about 45 degrees. It it that the tires never really warm up, or something else?
