[DeTomaso] How tough are the 15" factory magnesiumwheels?-UPDATE-"I'm no Mad Dawg"

[astephens]

Kerry,
     I can appreciate how you feel about getting all the miles you can out 
of those tires.  But,  I was just talking to a guy at work yesterday that 
had three of his five,  good looking tires go bad.  One grew a giant bump on 
the tread as he was driving.  The spare blew up while not being used and 
another tire blew on the road after he sold the truck to a friend that he 
had warned about the good looking old tires.  It does seem to be a bit of a 
gamble driving on tires that old.
