My tire guy, on the rare occasion that I use him, says the Dunlop AE II are the best HD tire out there, and he mounts hundreds of them a year. I usually mount and balance my own tires but had to give up on those stiff bias-ply HD OEM Dunlops.
That said, I had a Shinko 777HD mounted on the rear wheel of my RGS due to a puncture, and I can tell absolutely no difference from OEM. And they are a whole lot less expensive than the AEs. I have been running Shinkos on my KLR for years, no problems, ever. Can't say that about some premium brands, especially Avon.
Tire wear has a lot to do with weight, temperature, air pressure, road surface and the riders right wrist.
