Is it generally a good idea to disengage the overdrive (which is on by
default) in my 2004 Focus when doing city driving (lots of stopping/
starting, hills, etc.). It seems to make sense but then I wonder
whether it is good for the transmission to be regularly disengaging

I have the 1997 ford escort with the split port induction 2000
engine.  The A/C clutch engages and disengages while A/C is on in a 3
or 4 second cycle. It's been doing this for several years and makes
the car feel like it's surging.  I changed the CCRM last year thinking

ZTS stock size is 205-50-16
has anyone installed 205-55-16 ?
besides more selection in 55 series and better pricing
any difference in ride or tire wear?

I can flip up the back seat and release the seat backs from the trunk to get
them to flip down, but there is a cable that goes somewhere and makes it
seem like there is a lever in the car somewhere to let them down. Is it that
green plastic thing by the trunk release or is it ...
