I put this set of Avons on not long after they first came out at 34,500 miles and have just over 51,000 miles on the bike now, so I've got about 17,000 miles on them. The tread wear indicators are just now touching the ground. The best I got out of a set of Metz's was 12,000 and that was with wires showing. The front and rear Avon also wore evenly. Unlike the Metz's where sometimes I would go through two rears per one front tire. Most of my riding consists of a 70 mile round trip to work, all highway.. an occaisional weekend jaunt when the kids' sports allow, and a longer distance trip every now and then.
I love the way the Avons handle. They handle great in the curves, I mean I'm not afraid to push it, WHEN I have curves to ride on anyways. However, I think they do tend to spin a little easy when sitting up right and taking off hard. They are a harder compound in the center to help reduce wear, but that also means they are easy to spin. However they are softer on the sides, and I've never felt them slipping in the curves, even at peg scraping speeds.
They aren't bad in the rain either.. I rode to Shreveport, LA from here in San Antonio in a torrential down pour the whole way last year and made it alive..No squirming or hydro-planing that I could detect. Turning at intersections in the rain the rear can be a little slippery, but that's the nature of having 140 something lb/ft of torque and it's something I expect and can live with. I've ridden down a wet red clay road in the rain, and the guy behind me said my rear tire was spinning even as I was idling along.. lol
Over all, I am very happy with the Avons.. they were a huge improvement over the 3 sets of Metzelers I've been through. One day, I might try the dark side, but now that will have to wait another 17,000 miles or so..
