I am on my second set of Michelin tires. The first set wore out at 10,000 miles (16000KM's) - The second set was installed at a cut rate at the dealership that I bought the bike from. I was angry that the tires wore out so quick, so the dealership cut the cost by half.
So far so good. I am careful with the tire pressure, as I believe the original tires were over inflated. These tires are kept at 30lbs psi. the others were kept at over 40psi!! by dealerships recomendation. I am going to a different dealership now.
The tires perform very well. I feel they compliment the Dyna perfectly. I ride in lots of wet, rainy weather quite often, and I trust these tires. There is a Railway crossing in the middle of a long curve with rubber matting covering the crossing ties. Very slippery when wet, a true road demon. No bike can go throught this without some kind of drama in the rain. I am able to ride through this with confidence (and careful riding cause I know it's there).
If the Michelins are a deal, go for it, but I find them just a softer form of Dunlop tires. I feel Dulops are just as good.
