[2001 ZTS]

I had asked various Ford dealers whether I could put LX steel wheels on my ZTS, I thought there may be a brake clearance issue (this was in May 01 when I was a newb) but they were of no help.

So I asked the same question of Ford customer service and got back (abreviated):

"Ford does not recommend changing tire/wheel size on our vehicles for the following reasons:

-odo/speedo error
-drivetrain load (tranny/engine)
-suspension problems
-steering problems
-braking problems"

So from that I gathered if I had any of the above problems they would blame the snow tires/wheels and I would have a fight in the case of a warranty claim. I changed the wheel regardless.
