Relocating spare tyre under car.

Bloody good point there Eric.

I have been thinking about doing something like a contenental mount and
cover for the spare so it can be mounted outside the boot, but fully
accessable.

Since it would also need to cope with the full size wheel in case of said
puncture it would also mean that you could actually carry a full sized spare
on these long trips.

I dont know if anyone else would be interested in something like this but if
there is interest i have access to the engineering shop and a mate who does
the fibreglass stuff for the cover.

Perhaps this could be extended to cover the entire width of the rear instead
of just being round and add some additional storage beside the tyre.

There's a bloke in the UK who bought a second hand boot lid from a scrapyard. He drilled it and attached the various hooks n bolts and stuff to be able to fix a spare wheel to the outside. He'd then swap the original lid for the drilled one and head off into the sunset with the spare wheel firmly attached outside, and a happy and content memsahib on the inside (of the car, not the boot). All he had to do when he'd finished his hols was refit the original boot lid.

This becomes a problem with many vehicles with space saver spares. By their
very space saving nature and that when travelling, the items you take always
expand to fill the available space, means there will be a problem fitting
the standard wheel wherever the space saver was.
As the wheel will be very wet and dirty, always carry a plastic rubbish bag
to put it in. At least then when the Memsahib is carrying that precious
wheel in their lap, they will be grateful for your forethought and concern
for their well being.

You could carry 2 cans of tyre 'Pando' plus a small 12v tyre pump...I
believe some BMW Z3s came thus equipped ex factory.
My last puncture was...ummm...can't really remember, but I do recall it
was of the 'slow' variety and I average 40,000k per year! My space saver
lives in the boot on a daily basis, and stays in the garage while on trips
and I have no need for exhaust compromises...

Cheers

Do we really need a spare at all? How many of us have had a flat tyre in our
cars compared to other failures? In 65000km (over 2.5 years) in my 1992, I
had no flats but did have the radiator top tank split necessitating a call
to the AA for a truck to get the car back to where it could be repaired. I
don't carry a spare radiator tank.
In 10000km in my NB I have had no punctures. I have had the relay
controlling the fuel pump fail (last week). At least this happened at home.
I don't carry a spare relay.
I have had 3 flats this year in my Isuzu Bighorn so a spare is definitely
necessary. However two of those were at the same time and I carry only 1
spare!
Last year I had 13 punctures, all off road so it is necessary in that
vehicle.
I have had only 2 punctures in the last 30 years in my other vehicles (as
far as I remember) and I do up to 80000km a year when all added together.
Is a spare really necessary in normal driving today? I don't think so. The
BMW idea is probably the most sensible way to go.

Well put Grant...exactly the point I was endevouring to make!

I agree Grant, that is the conclusion I came to as well, especially on a
trip.

I guess I have had more than my fair share of punctures in recent years,
mainly because, living in a developing subdivision, more nails were dropped
on the road by builders. All of my puntures have been close to home.

The tyre Pando solution seems to be the way to go, along with ensuring that
your tyres are in good nick to start with.

Anyone know what the AA position is on helping if you are not carrying a
spare? It would seem to me that if they will help then the membership would
be well worthwhile - certainly better than squashing the wife beneath a road
wheel, plastic-wrapped or not!

A SC does sound more appropriate - instant torque. Mine is turbo'd
and it's somewhat frustrating pottering around behind someone doing
under 50 km/h. It's all too easy to think 'bugger this' and be doing
some supra-legal speed in a few seconds, in theory of course.

BTW - a turbo does produce back pressure (less so with a
bigger,laggier turbine), which reduces volumetric efficiency/power. So
it's not a totally free ride. Also compression doesn't *need* to be
lowered, but you do need to manage boost and ignition fairly
carefully.

I'm actually commuting in a big ugly diesel wagon at the moment - it's
much more suitable for gnarled up traffic than my grumpy little MX5 !

Hi all,

Just recently my husband got me to pick up the repaired Microwave. Its quite
a small one so thought it would fit in the boot. It didn't and I had a
passenger who had a bag already on his lap. Solution was to put it behind my
seat. Fitted neatly too. Just as well I've got legs on the short side
though.

Hi Kevin,

Memshab always drives unless husband begs.

Dash light not fixed but have found the culprit wire under dash inside car.
A little tweek gets it going again.
