Moreover, for those interested in VVS aviation of the GPW era, there is the inevitable expectation of the usual 'exception to every rule all the time' solution. Surely, the same production that gave rise to three differently armed LaGG-3 Series in a single week would have used a plethora of wheels, tyres, and such like depending upon the weather, the day of the week, or if the month had a letter "O" in the spelling....
Not so. Quite remarkably, the Soviet use of aviation wheels and
tyres during the GPW years was so consistent, one is tempted to employ the rarely
heard "s" word ('standard') in regards to these items. Most VVS fighters built
after 1940 utilised the same 650 x 200 mm tyre mounted on a similar wheel in
many programmes, with only minimal changes, and also used the same tailwheel
of 300 x 125 mm size. This kind of consistency was unusual, to say the least,
and it causes one to wonder very much (indeed, to assume, really) if these wheels
were not being delivered by a single sub-contractor somewhere? Be that as it
may (and answer to this question is unknown currently), this similarity in practice
gives us a real chance to investigate the appearance of VVS wheels of this period.
Mikoyan and Gurevich
The MiG manufacturing programme spanned roughly 13 months, during most of which time the entire project was in considerable disarray. This observation probably explains the large number of tailwheel units that can be seen on various MiG-3 fighters, and the diverse methods for housing these (or not) in the rear fuselage. However, for the main wheels the picture is rather different. These appear to have been the same wheel items in virtually all cases, and moreover show the same tonal appearance on the available photographs where a view of them is possible.
Anecdotally, the claim has always been that the MiG-3 wheels were painted with the trademark Soviet "green" colour (type and nomenclature unknown) which one may see even today on wheels, intake cones and such items [one lacquer described in the 1974 VVS camouflage regulations refers to this paint as 'KO-814 aerolak', but adds in the diagram, "or others..."]. The two surviving and un-rebuilt units we have for examination do seem to show a green paint on this in roughly this category.
In the photographic record this claim does not seem to be in
dispute. When visible, the wheels on MiGs do seem to have a tonal appearance
that would correspond to this hue. We also have available two colour photographs
which show these items, and despite the very dubious colour registration on
such film, they would seem to support a green interpretation, as well.

Therefore, assuming that that the colour in use was indeed this kind of ubiquitous green hue, the resulting wheel and 650 x 200 mm tyre would look like this.
The MiG-3 featured a great number of different tailwheels types,
and as yet there is not really any good information available on many of these
(look for later editions of this article). However, one unit which does appear
regularly and for which useful photographs exist is this wheel. The tyre size
is unknown, and in fact this might be a solid hard rubber item, just judging
by its appearance.

The Lavochkin OKB
Wheel use and painting in the various Lavochkin products seems
to have been split into two phases, with the early period showing older and
less standard behaviour, and the later pattern demonstrating considerable uniformity.
Up to the end of 1942-- that is to say, the main portion of the LaGG programme
and the early days of the La-5-- the appearance of these wheels are varied.
They all seem to be the same unit mounting the usual tyre (as seen on the MiG
and elsewhere), but the tonal properties of these on the available photos are
mixed. Some units show a darker colour which might be in agreement with the
'Soviet green' idea, while others feature a lighter shade similar to, or lighter
than, the undersurface colouration.

The photo to left shows a 1942 vintage LaGG at Tblisi, and the wheels have the same appearance as many MiG wheels. The central image shows lighter tone. The picture rightmost shows the lighter tone, but also a cover which is observable on some early Lavochkin fighter wheels. The unit appears to be the same as elsewhere, but with a circular cover over the central hub area.
Based on these observations, we might speculate that the LaGG could feature wheels painted with the green colour, or in other cases not painted at all (bare steel), or with the undersurface colour in use (AII Blue or AMT-7).
On the later Lavochkin fighters such as the La-5FN and La-7, the wheel appearance is uniformly light in tone. The impression one gets here is for an unpainted wheel, or one finished with the undersurface lacquer.
We do have available several surviving La-7 wheels of which one
can be fairly certain regarding their authenticity. Of these 7-8, six of them
look to have been delivered originally in an unpainted condition (the steel
surface demonstrates corrosion and oxidation under the current layers of various
non-aviation lacquer). One (and arguably two) unit shows what is thought to
be AMT-7 Blue sitting directly on top of the steel surfaces, i.e. showing no
priming. This lack of primer usage is fascinating if one takes into account
the very great... erm.... shall we say, "enthusiasm" of the Soviet factories
for using ALG-1 Primer on such items. Is this evidence that the wheel units
were supplied by a sub-contractor? Be that as it may, here are some related
photos.

The photo to the left is from an La-5F in 1943; next from an La-5FN in 1944; lastly an La-7 from the same year.
Taking these observations into consideration, here are the likely appearances of the various Lavochkin programmes' wheels.
In the matter of Lavochkin tail wheels, happily there seems to
be a standard (good heavens!). A wheel identical to that on the Monino La-7
exhibit can be seen in various photographs of both LaGGs and La-5/-7s. It looks
to mount the typical 300 x 125 mm tyre, as used on most VVS fighter tailwheel
units. The appearance seems to be uniformly light in tone, suggesting either
unpainted surfaces or the undersurface lacquer.

New Findings
As a final word, let us be certain that exceptions to these general
observations are going to be found. We are only just embarking upon a detailed
examination of these units, and this material cannot possibly be regarded as
definitive. As new information and photographs become available, new and updated
portions of this article will appear.
