not a Pandora's box just another technical detail to be worked out.
I looked at all the photos I have on the Yak-3 and they all show the Yak-1 tires.(on Yak-3 rims)
it seems that True Details has made an error there, very rare for them to make a mistake.
the True Details wheels/tires (48-054) are the later type wheels used on the Yak-9.
the wheels(rims,hubs) are the same it is that the tires are a smaller diameter.
page 64 of Aircraft Monograph 14 by Robert Bock (AJ Press) shows the Yak-7 type tires.
these drawings are from Modelist Konstructor magazine, they did the Yak-7 first (if I recall correctly)
then did the Yak-9 later without correcting some of the details.
have you tried to use copy/paste at Babelfish.altavista.com ?
it gave me a much better translation than online-translator.com (it is usually the other way around)
