Either tighten the valves or if you really want solid rubber tyres, I would look at Amazon or AliExpress, which is where I bought the inner tubes and tyres because you can't get anything in Switzerland. AliExpress also delivers to Switzerland without any problems, it just takes a while.

No, that's not possible, I have asked everywhere in Switzerland (of course not üüübbbeeeerrrralll ) about the possible places. Nothing to be done or then again complete moon prices because you have to order it elaborately. So Amazon two pieces for just under 20 euros. Good if you have a delivery address in Germany and are often there. I have one more tip, maybe ask dealers who sell prams, it could be the same size. It's important to have an angled valve, otherwise it won't work. Have fun with the scooter.

They are not solid tyres.... Inflate the tyres well. The Trotti rides super and pleasantly. The braking effect is not the same as with solid rubber tyres. You need a bit more effort to drive fast than with standard wheels.

As far as I know, you can get solid rubber wheels from Hudora. However, I would not recommend them: Pneumatic tyres are more comfortable and not as noisy.
