Yes, I would be interested in hearing about the Revo 3 long-term experience as well!
I ran the original Revo for several years on my 4th gen 4R and loved them, but when they went to the Revo 2 I didn't get very good longevity, so I was looking for a different tire. The Revo 3 had just come out when I needed to replace, but not much was known on them at the time. So I switched to the Yoko Geolander GO15 AT and have had them on just over two years. The Geo is a very good and popular tire with great reviews on Tirerack.com. It is a really good street tire (very good in wet & dry) which has done just fine the times I've been offroad. It also carries the snow rating, which I like as I might get by without having to put chains on if encountering snow (many states will let you go without chaining up if the snow symbol is on the tire).
The Revo 3 is getting really good reviews on Tirerack. It is, however, one of the pricier AT tires out there. And it's still probably a little too new to get a feel whether they fixed the mileage issue many complained about with the Revo 2. It also doesn't carry the snowflake symbol - even though many reviewers said it does well in snow. But the price difference amounts to more than $150 between a set of four Revo 3s and a set of Geos. I'm waiting to see if the price of the Revos comes down and if people make it full distance on these tires. Then maybe I'll consider . . . but until then, the Geo is a fine tire that seems to suit all my needs - hopefully I'll get the full 60k miles out of them.
