Russia in general is not a problem for motorcycle tyres as there are many bikers - therefore many bike shops and facilities. Mongolia and Uzbekistan were specifically mentioned at the start of this thread, and there are very few bikers in those places, therfore a shortage of support functions for bikers.

If you are carrying your own tyres, any car tyre changing place will be able to swap them over, in any country.

true that, could try a car shop, thanx ..although once in Thailand the car shop did not want to do it..depending on bike I guess ,but they probably just didnt know or unsure etc

"Agent Orange" in Almaty have tire stock and trained tire service
Мотоциклы КТМ в Казахстане, Алматы

^ Good place and good people, some English spoken.

You could also try FreeRider.kz or speak to Marat at Silkoffroad -motorcycle tours and rent in Central Asia

Almaty is certainly the best place to be looking in central Asia. The BMW dealer is still utterly useless though unless you want a 4x4 with tinted windows.

The both statement are true ) BMW mottorad was opened officially only few months ago. And the service not great there (rumors). Freerider have tires in stock (may be KTM as well) when other repair centers only working by preorder.

We are company based in Ulaanbaatar and just opened a branch in Western Mongolia BayanUlgi just 100km from Tashanta/Russia can supply you with various size new tires on both locations pls drop us an e-mail and can send you a quote.
