Toyota builds cars and has no rims

Hello, after 20,000 km Toyota-joy now the first blow with the rubber hammer in the middle of my so enthusiastic face so far. Nowhere there are 195 /65R15 rims for my Avensis. That means, yes, there is, but with 2 weeks delivery time. Now that almost more Toyotas drive around than some German cars: Do they have the A… on? So a stupid rim press does not cost the world, since you can tilt at every dealer times a pile of 100 pieces on the back of the yard as bulk goods, It doesn’t want to buy every 205 winter tire for half a fortune, which usually do even worse in the test than 195. Is there any remedy? Can one possibly replace the thing where the rims are screwed on against one with Opel rim mount or something?
