My commute is 86 miles each way so 172 miles each day and around 60,000 miles a year.
Avid EnVigor is great on wet road. My other tires used to lose traction every time you start from a stop. this tires surprised me by not losing tractions. light snow even medium snow is fine .
the tire make my toyota sienna 09/10 van handle like a car
this tires is really live up to its name .high performance all season tires
My only complaint is the road noise which is higher than other tires i'm used to.
This is my second set of Avid EnVigor. i'm planning to try out a different set of tires. just for the sake of trying. i have change to a new set of tires every year any way
the treadlife is 60,000 miles max 55,000 to be safe. which for me is 1 year worth of driving. and i rotate the tires every 20,000miles.
if you need a High Performance All Season . get The Avid EnVigor.
remember that they have to put a softer compound to make the tire grip and stick to the road better thus the shorter tread life. and a bit noisier because of the aggressive tire pattern
