Just a quick warning not to count on tires in Novosobrisk.
When I came through in August headed west I had to buy used tires to get further down the road. NBS had a very poor selection of tires and no Euro dualsport rubber, ie.Metzler, Continential and so on(I know they are produced elsewhere).
All I can say is tires are a bitch in Russia and Mongolia.
I shipped two by train from Vlad to Chita but you need someone to pick them up(sometimes the Russian biker community can help so try them).
I hate to carry tires but in Russia it seems like it is the only alternative to Russian tires.
You can run them but the profiles are very flat and the rubber is long wearing but slippery.
Maybe others can comment on their experiences....
