Unless you figure out the best way to handle the tire change, just to make use of your knowledge, then I wouldn't put too much more effort into it. Since PD has been made aware of the issue, once and for all, it is up to them to fix it.
The problem is that every time I get to this point of directly having to describe a problem to them, its as if they have no clue that it is even happening. That is why I keep on sending in bug reports, even though they don't respond about them, therefore I have no idea what effect the reports have other than seeing the fixes show up - eventually. It is pretty disheartening, sometimes. However, a change is coming to help make this sort of communication with them a lot better for all of us, if it works out as I hope it should.
In the meantime, the better a problem is described, the easier it is for me to point it out to them.
