Optional spare wheel

It is only a stupid question AFTER you are told the answer!Smokey001 said:
I asked a Traffic Police Officer if it would be illegal to drive with a 14" spare wheel when the other wheels were 16". He said he thought it would be but was not sure. he said he would consult Fords and let me know. He never replied because after got the answer he felt stupid!
The wheel size refers to the size of the rim (alloy). Therefore a wheel can have 14", 15", 16" rims with the same size tyre which keeps the rolling size the same. All that changes is the height of the tyre wall. That is why you see some wheels with a very small tyre wall and others with a large tyre wall. Their rolling wheel size is the same.
If you change the rolling size you must adjust the electronics to take account of the different circumference of the tyre as it rolls along the road. Bigger tyre, less rotations for the same distance, hence speedo is wrong, distance traveled is wrong etc.
If you change the rim diameter and not the tyre diameter, everything stays normal.

Same goes for winter tyres on smaller steel wheels. As long as the overall rolling size is the same all will be ok.
I think 14" - 17" inch wheels + tyres are all the same rolling radius. It's only when you jump to 18" or above do things get out of sync.
Nice little thread here that allows you to work it out;http://www.mkivsupra.net/vbb/showthread.php?237553-Understanding-the-Rolling-Radius-and-the-tyre-Profile

I ordered a spare wheel on purchase and to date have not checked it although I do know it is there.
Today I had a service and on the report the mechanic had written 'space saver'. I thought 'spare wheel' meant spare wheel and had assumed that is what I had. I need to look now.
Does a spare wheel mean a space saver? Is that what everyone has?

As far as I am aware, there is no 'Full size' spare available for the B-Max. The only possibilities are the 'Space Saver' (Or Pretend) spare and the horrid toothpaste (aka 'buy a new tyre and possibly wheel every puncture')

Try breakers yard normal sized wheel from a Fiesta will do the trick remember you will also need a wheel Jack be carefully must get the correct one it has a slot which fits the jacking points. See your instruction manual. With a bit of luck about £50 or less for both. Make sure you see before you buy,almost new will be an ideal deal.
Often a Breaker will get a write off fiesta with a never used spare. Of course a brand new steel wheel for a fiesta can be had or what about a new spare alloy,I tried very hard for a second hand alloy no luck.but above GET A SPARE.

I got a 15 inch space saver with Pirelli tyre, both unused through breakeryard.com, the supplier being F P S ( Ford Peugeot Supplies ) in Essex. This fits perfectly in the space saver space, no need for docking parts. Ford tyre associates gave me a jack, wheel brace and steel nuts. Total cost including delivery and VAT £48..... Well pleased.

I should now have spare wheel sorted by Tuesday - been a bit of a slog but I can now claim to be an expert on tyre/wheel size combinations now.
From Ford, all BMAX have same spare wheel size The wheel is 15in and all the data is on Makems photos above. The tyre is 125/80R15.
Ford make this difficult to find but it is handbook under tyre pressures.
Note
on drivers door, there is a label but on mine (and 2 other showrooms) the label is incorrect
showing 125/60/R15 - there is no such tyre available.
The photos were great because the one showing how jack etc fit into slots saved me from trying all combinations.
You could also get a spare 15in steel wheel with standard tyre.
This is too deep for the spare wheel (Spacesaver) well but (according to mechanic) you can get a foam insert to raise the cover level of boot.
also, if you do a search on spare tyres for BMax
you get directed to fordpartsuk.com - this is not a ford official site.
it offers a 14in wheel with a 175/65R14 tyre
you pay your money and take your choice.
spacesaver tyres are scarce - little turnover

Sorry if last post seemed to be cut short.
I had to attend to something and when I got back I may have been timed out (or something)
I could not add to post but could submit it.
Tyres are scarce and I have located one for fitting on Tuesday.
Hopefully it will never see light of day again.
I have never needed to use a spacesaver before but the following seems logical to me.
If I get a puncture in back I will fit spacesaver
If I get puncture in front, I will take good wheel off back and replace with spacesaver and
replace deflated front with full size.
again hopefully this will not come to pass.

So far all the discussion has been focused on 15" / 16" wheels. I've now had my B Max Titanium for 2 months. It came fitted with the X Pack. This provides upgraded wheels of 17" with 205/45 R17 tyres. In the boot there's a bottle of gunk + compressor. I'm not happy with this arrangement as the first time there is a puncture you can say goodbye to the tyre as most reputable tyre repair companies won't put their name to a repair (not being able to see the extent of internal damage due to the gunk) Ford, in their wisdom do not provide a spare wheel option for this size of wheel (whoever thought up this combination should, in the words of Jeremy Clarkson, be taken from their bed early one frosty morning, be stud up outside their their front door for all to see and be shot - slowly until dead) The solution I'm thinking of is to obtain a scrapped 4 stud alloy of Ford pedigree and fit a suitably sized tyre with minimal legal tread depth to act as a spare. However this talk of "Global fixing devices" is worrying me a little. If I take the punctured tyre off and put the spare on (rim not necessarily of B max origin) and secure with existing nuts am I shooting myself in the foot?
Any thoughts would be much appreciated [:x]

Having owned a Mercedes Vaneo for 3 years and two punctures (Vaneo Brotherwood Wheel chair conversion) with as you say "can of gunk" and compressor, on both occasions I did not have to usegunk, only compressor to inflate tyre to get me to a tyre repair company.Therefore as in dad's army speak, "don't panic"
