AVID ENVigor ZPS(High Performance All-Season)
Primacy Alpin PA3 ZP(Performance Winter / Snow)
My opinion on these two tires goes as follows.......
.
The Envigor is a quicker transitioning tire and is slightly better than the Alpin in wet traction performance.
The Alpin's edges had to wear a bit before I started liking the tire. This was because of the little wiggle, it would give me. I would come out of a curve or parking lot,in a hard lean and hitting the throttle, and it would momentarily loose traction - nothing too serious. The Alpin rides smoother and seems to wear longer for me than the Envigor.
I favor the EnVigor, yet also still ride the Alpin at times. I have both of them mounted up, along with a Stone 704. Love playing around with tires.
