Jeff, you ever driven on icy/snowy road with the tires like that?  I
only say
that because my 4kcsq had tires slightly different in diameter.  Drove
fine
until the first day of snow this winter... with the center diff locked
it
fish tailed like you would not believe.  Stopped in that night and got
two
tires that matched the front and no more fish tailing.  Doesn't take
much 
to screw up the traction.
