Re tyres sizes
Standard 12 spoke tyre is 225/50/16
This is a 12 spoke fitted with a 205/45/16 which is on an XR4
3% reduction in circumference from the 225/50 which would give a slight increase in acceleration on the Scorpio and make the speedo read 3% higher (every little helps)

I think much smaller tyres look a little funny because of bigger cap between them and wheel arches. Needs lowered suspension to not look so odd
Just my opinion 
In Sierra 205/45R16 look very good

Regarding the VSS teeth. When I swapped VSS in mine, the tooth count was 21 on my 24V. I double-checked too, even marked the point where i started counting. My speedo has shown speeds a little more than the actual speed, but the internal speed as reported by the in-dash diagnostics was exactly the same as from a GPS. I strongly believe the pinion on mine is original.
Apparently as the number of teeth for 2.0 was also 21, 2.3 was 19, there must be something different, perhaps related to only the 24V used the A4LDE box. It would be interesting if this could be verified further. E.g. the 12V has a A4LD with the same diff ratio.
As is stated in the article text, the different VSS are fully interchangable. So are also the pinions, but only if accompanied with the corresponding retaining clip. So make sure you get a clip and pinion together if the styles are different.

I never got mine from Ford, after two months waiting. Meantime the old one was installed without problem.
FWIW there seems to be only two for petrol auto versions, 19 & 21 teeth:
19 teeth (2.3 only): 6313349
21 teeth (2.0, my 2.9 24V had this): 6313353
Still don't know what 12V and TD uses.
Clip: 1631791 (verify this is of the same style, no other offered)
There are two designs of pinion and clip. Old clip+old pinion are together functionally equivalent with the new clip+new pinion, and can be installed on either the old or the new style VSS.
You'd get it much quicker if you accept a used one, unless somebody promises a date Cost around 25 euros.

It appears so. Based on on diff ratios I would have expected 17 teeth, but my original (AFAIK) had 21 teeth, and there has been no counterexample posted either. Even FMD based on VIN suggested 21 teeth, but I was suspicious of this. My theory is the counterpiece in the gearbox the VSS takes readings from varies after all, but this may be A4LDE specific. We need somebody to check a 12V & TD to be sure the pinion will not have to be replaced to swap diffs.

19 for 2.3 and 21 for others, check the posts above. Remember, the 24V A4LDE might have a different wheel/pinion *in the gearbox* than the A4LD on the others. If you swap your diff to a 4.27 you put a 21 teeth pinion in, if you put a 3.64 I would leave the 19 teeth one in, and hope the error will not change.
BUT the Granada mk3 facelift with 3.64 or 3.62 diff used an 18 teeth pinion with A4LD. This would I be looking for. Finis 3512264 & ring 1635335. Strangely, ths does not show up for Scorpio II.

Humm. Could be worth checking which kind of pinion does my old and rus.. trusty Granada III have..
should more teeth increase speedo's value or vice versa?

Less teeth -> more revolutions per second -> higher speed is shown
Bet you have something like the metal VSS in your old one. Atleast you will be able to steal the pinion+clip from it.

Guys we're getting confused here....
All the Scorpios used the A4LDE box not just the 24v apart from the 12v and the diesel.

I removed metallic clip before taking photo. But that clip was just for holding the connector?

There's a screwhole right where a part has snapped off (check the picture of the sensor in the first posts).
I think you should be able to prise it out very easily (unless glued there).

The clip also holds the sensor in position,it SHOULD as the they say in the Haynes manual just fall out

correction:
PHEW, finally it detached.. d*mn it was tight 
I found there is 20-teeth pinion.
If I want speedo reading to _decrease_, should I put that pinion to newer scorp (2.3) ?

If your old one is a 19 teeth, yes. Sure you don't need you old scorp?
