Not Russian - that's Ukrainian. Ukraine is broke, bankrupt and destitute (apart from the billions the US throw at it every year, and just re-equipped militarily) - tyres are the least of their problem
The Antonov Design Bureau is still located in Ukraine, and going broke fast too. Antonov Airlines - the aircraft you see here and also the one that flew into Newcastle/Williamtown is owned and operated by Antonov Design Bureau.
Because of Antonov's situation, having certification and safety inspections renewed is a major problem for operators of the 124.
