Brine,

I recognize China's manufacturing capabilities adn yes I have never been to China for business purposes but visited Japan 6 times fro a total of 36 days. On one trip we went to Shanghai for shopping visit one night & one day.

Since you promote your tires are "High Quality", what makes them "High Quality" and won't break like the low cost (the price to me was not so much lower than the US made higher quality screw) - low quality wood screws I experienced.

Everyone claims high quality - OK prove it not by trial and error method - quantify it - more this (carbon black, higher durometer, thicker tread, etc than leading estabilished brands)
