you ever wondered why there is enough space in the wheel-well of your
car for a real spare tire but the manufacture has opted to short change
you and has substituted a temporary or what is known as a compact spare
haven’t been short-changed, there is a reason and obviously it’s not to
save space (these tires used to be called “space-savers”) as there is
ample room around your compact spare tire to accommodate a real full
size spare tire.And
it’s not to save money. If you were in the market to buy a new compact
“temporary” tire (I have yet to meet someone who has) on average you’d
be paying 20 to 30 per cent more due to the fact the tire manufacturer
will build and sell thousand more regular tires to one space saver.An
example, one of the more popular sizes of tires can be bought for $114. The compact spare
tire for the same vehicle costs $155.
it has to be weight, the less weight of a car, the better gas mileage
it will get. That’s good reasoning except a space-saver isn’t all that
far off the weight of a real rim and tire and isn't a big factor
unless the spare is eliminated completely. This is the new trend that
most automakers are following where 35 per cent (and climbing) of
vehicles sold today do NOT have a spare tire. The backlash from
consumers is now being challenged. Feeling the heat Honda has equipped
all variants of the redesigned 2015 Fit with a spare tire after
dropping the no-spare-tire feature on the previous model.The
most obvious reasons, saving space, better fuel economy, cheaper tires
none of these are why you now have a compact “temporary” spare, it has
to do with “shimmy.” “Shimmy” is the effect of tires not running in a
pattern to which they were designed to run and causes the steering
wheel to slightly vibrate back and forth.If
we go back in time, back to 1973 when automobile manufacturers swung
away from installing the old style bias/belted tires in favour of the
new radial ply tire. These new style tires were developed in the late
‘50s and into the ‘60s for jet airplanes that needed a superior handing
tire for takeoff and landings. Radial tires were much like alternators
and disc brakes, first for the airplane industry and now being fitted
the auto manufacturers were confronted with numerous customer
complaints of a shimmy in the steering wheel and always after the
vehicles tires had been rotated. The problem was simple, the owner or
servicing garage wasn’t following the new way of rotating the tires of
back to front and front to back and to NOT include the spare tire.But
that was contrary to the owner’s thinking, why not use the spare tire
rather than to let it sit there doing nothing. Rather than follow the
new way, the old way was used of Xing the tires for rotation. The spare
to right rear, right rear to left front, left front to left rear and
left rear to right front and everybody would be happy if it weren’t for
the fact that this shimmy would occur. The spare was then included in
tire rotation, regardless of what the owner’s manual said.Radial
tires when first installed and run in one direction and then changed
and now spun in the opposite different direction ie. left rear spinning
one way and now on the right front spinning the opposite way would
create a shimmy.The
warranty claims were piling up something had to be done, thus the
temporary or space-saver tire was created as a spare tire. The light
bulb now on, owners and servicing garages adopted the new front to
back, back to front that solved the shimmy problem once and for all.One
final item of why all the excess space when the compact spare is that
much smaller? When a car is designed, it’s not only for the North
American and European markets, it’s also for worldwide sales and
some countries, especially the third world ones, the vehicles wouldn’t
be bought if a regular spare tire was NOT sitting where it’s supposed
to be, shimmy or no shimmy. Thus the bigger spare tire wheel well we all have .
it was VW, then Mitsubishi, now FIAT and make no mistake about it, the
rest of the car industry is equally guilty of commonsense in the face
of the fanaticism that prevails among the econazis., they just haven't
been caught - yet!
What is going on and what should a poor car owner do?
bureaucrats in the EPA and in Brussels looked up at the ceiling and in
a moment of religious fervor, decided on the emissions levels that they
wanted for carbon burning vehicles, never mind if they were achievable
The engineers in the auto manufacturing groups knew
instantly that these demands of purity could not possibly be achieved
and many questioned the assumption that their petrol burning creations
were even responsible for the the climate change that many doubted even
existed, or had even been proven to a decent level of engineering
(There are so many well documented scandals
concerning the way that beholden so-called scientists have fudged the
figures on global temperature change that their credibility is in
So what did all these practical engineers do?
manipulated their engine management software to give the fanatics what
they think they wanted, at the same time giving the car owner a car
that was not only a lively, responsive thing to drive, but one that
produced spectacular increases in fuel economy.
They should all be awarded a medal for practical commonsense in the face of stupid bureaucratic meddling.
So what now?
It all depends on what you get offered.
you cannot re-licence your car until the software has been modified,
you're screwed and your car will never feel the same again. Both from a
driveability point of view or that of fuel economy.
The last thing you want to do is go anywhere a dealership that insists on changing your engine management soft ware.
If you get offered a cash payment with no strings attached, take it and be happy.
you get offered a buy back, it will be at the depreciated, used car
value, and not what you paid when the car was new. In this case it
comes down to a financial calculation rather than one which directly
concerns the vehicle.
The bottom line is:
NOT HAVE YOU CARS' ENGINE MANAGEMENT SOFTWARE MODIFIED UNLESS YOU HAVE
NO OTHER CHOICE, OR UNLESS, YOU'RE A FOAMING AT THE MOUTH ECONUT.
