i dont think any amount of recalibration will do the trick here. if you had
studied the tire specs prior to purchase, you will see that the rolling circum-
ference differs vastly between front and rear. accordingly the front tire
will be rolling 755x per mile, whereas the rear is rolling 729x per mile.....a
difference of 188' per mile....3" per revolution. that's extremely bad.
are you sure of the tire specs you posted? if so, why did you select these
tire sizes?

your rears should be 275-35....or, your fronts 245-45.

because the differential in rolling rubber per mile has exceeded the tolerance
limits of the cruise control, it shuts down.


I just pulled the above off of the MB forum, do you think this could be the root of the cruise control problems
