This morning I took a ride up to Metal Dragon for some new shoes for my bike. Over the past year I've been reading this and that on the board about the Michelin Commander IIs and thought I might add to the conversation a bit. Having done a quick search, I didn't see anything specific or vary recent about rider experiences with these tires. So here goes.
Even though it was only a 35 mile ride home and a bit around the neighborhood, I feel like yelling from the rooftops, "BUY THESE TIRES!!!!" Aside from the low speed handling improvement over new Dunlop 402s, these tires are simply amazing. One of the most noticeable improvements was with the uneven road conditions on hwy 80 between Hayward and San Jose. They're re-stripeing the road and adding lanes, so to remove the old paint, they remove about 1/4-1/2 inch of asphalt. This leaves a grove about 8-12 inches wide meandering all over the road, depending on where the old lanes went. On the ride up, I made every effort to avoid these groves, because it tended to toss the bike or grab, preventing an even transition for both front and back tires. After the new tires were installed, no effect at all! I couldn't even feel the groves. I'm simply amazed at the difference in handling at all speeds.
I have to admit, the front tire had over 20,000 miles on it by the time it was changed today, so it was done - kaput. It was cupped and had a ridge off to each side of center. I'm sure that is one big reason it was grabbing onto the roads imperfections so strongly. Even so, this tire has done this as long as I can recall while riding this bike. It never handled as well as they do now.
I believe Jim installed the 140 on the rear, but now that the bike is parked, I can't see to confirm. Tomorrow I'll have it up on the lift and will check it out then. If they did put the larger tire on, I don't believe any cutting was necessary. This will be confirmed as well.

Hope this helps someone with their decisions...
