You didn't tell us what vehicle these would be going on. That's important because if the wheels are different widths, the tires might not fit and TUV might not approve such a change.

I did a quick check with the resources I have and they don't list a 205/50R15 as OE on anything, and a 185/55R15 is only the GM Spark and Fiat 500e, but my source is for US vehicles only.

And it appears that going from a 205/50R15 to an 185/55R15 is going DOWN in load carrying capacity - again, that might run afoul of TUV.

I assume you want to make this change so you can rotate tires, but if the wheels aren't that same, that would be ill advised and maybe even impossible.

So 2 questions:

What vehicle are we talking about? Does the vehicle have different wheels front to rear?

What process does TUV use for such a change?

(OK, that was 3 questions!)
