My '99 E-350 5.4L has pretty much ruined new front tires in 20,000
miles. They've worn their inside edges (though not to the point of
undriveablility) far more than the outside, and they've become so cupped
that it's like driving on a cobblestone road. The rear tires are like
new (all four put on at once). My '89 E-250 did the same thing, but this
van only has 43k miles on it! And, it has the same vibration problem
that the '89 did. Does this happen to anyone else? For the cupping, I
need to check the shocks, I guess, but if they went bad in 43k miles,
that would be pretty unusual. The thing tracks and handles fine, but
there must be something wrong with the alignment for the tires to wear
so unevenly. Any comments or suggestions appreciated.
PS- My '97 Grand Marq with 172k had its last set of tires, cheap ones
from Sam's Club, last 90k! I know tires won't last that long on trucks,
PSS- Gotta hand it to Ford, this van got 17.5 mpg to Colorado and back,
pretty good for a heavy vehicle.
