PR3 in front, 110-80zr18, Michelin Commander II in stock size in rear, please note the II after Commander. I had a stock size Avon Venom in back, had to replace prematurely do to some sort of carcass failure on my last trip. As an aside, I had sworn off Avon Tyres 30 years ago cuz they sucked then. Convinced from others on how "good" the Venom was, I tried one. No more. The Commander II on the back lets me accelerate out of a corner without getting squirelly, and rides a LOT smoother. They also have sliica in the thread to help with wet weather, but it will/did slip slightly when heavy on the throttle coming out of a corner on wet, very new blacktop. I was trying to locate a Shinko Journey 890 for fitment, but could not find one in stock in the Mpls/St Paul area. I found the Commander II and pulled the trigger. I was almost in the "if it's black, round, fits, and holds air" mode of shopping, as I was on a trip. The Commander II is a pleasant surprise, tho will probably fit the Shinko next. When the Shinko wears out, the bike should have over 200k miles on it. I think I'll get something different to ride at that point.
Not to inflame folks here, but Avon Tyres sucked thirty years ago, and they still suck, IMHO. Your opinion, and mileage, may vary. My experiences with Avon tyres has not been good, at all, ever.
