For me, no difference in quality between my 2 sets of Hankook tyres, Prime2 from Korea and Noble2 from Indonesia, both equally good in terms of manufacturing quality.

iPhones are made in China.
Sony RX100 was made in Japan, then later in China, still the same quality.

Michelin PS3, made in Thailand, and made for SEA conditions, weather etc.
Parallel imported German made PS3, tends to chip or deteriorate faster.

Then again, these are all generalizations, and other brands/tyres may buck this trend.

Country of origin to me is less important than overall brand quality and whether they are produced and approved for the locale it is sold in.
