In the fleet we use Michelin in the class Cs, but not in the As. The As had sidewall cracking in all michelins after 4 years, and these are tires that are being used in average 20K miles per year, goibg out at least every 2 weeks, so there is no "lack of use" damage. They are way overpriced and they are not better.
We have used Toyo or Yokohama. They have worked great. In my Alfa I have goodyears in the drive axle and doublecoins (I think) in the steer (they came with the coach). They are in great shape and drive great.
Don't get wrapped around the Michelin talk. Look at the tires the truck drivers use, you will see that there are not too many of them in that group.
