Youngster,

I am asking him to substaniate his claim of "High Quality" solid tyres.

So far I have not been convinced products made in China are of "High Quality". I do a bit of wood working and I will never again buy a simple wood screw made in China - commonly available in the "Big Box" home improvement stores in the US. They break off too often with just a bit of tightening. I pay a little more for US made screws - they work & don't break = High Quality in my book.
