Peter,

You might check through the trip reports from the caravana group in South America.  I believe one of Larrys earlier posts on "things we have learned" talks about the Yokohama tires...(I am not certain it was Yokohama tires.. but pretty sure it was) not so good a report.  Those who chose these tires have had tire trouble while those useing the Michelins have had none..

Worth checking out..
