I wouldn't have thought so, we make roads just the same way they do. We use the same formula to mix and lay the asphalt, so why would they change them?
It's been said forever there are slight differences in tyre properties from country to country, whether it's true or not I don't know.
One thing I see as a great advantage for us is Australia uses all weather tyres where many countries in the northern hemisphere fit seasonal tyres because of the extreme cold/snow and have to swap them at the end of winter and summer which I think is a pain in the neck.
I've also read that tyre reviews from one country doesn't necessarily applied to another but I look at it this way, if it's a high end performance tyre and there are some differences then those differences probably don't have much of a real world impact.
I'm more concerned about the reviews themselves as in Australia it is known that the tyre companies wine and dine and give free track days to the reviewers and in my books that means a compromised review.
Sometimes the only impartial review you can find is from an overseas source and that is at least as good if not better then some of the bias you read in Aussie magazine reviews.
Still no matter where the reviews comes from it's better to note which tyres constantly make the "best of' lists regardless of their order on the list and gravitate towards them.
A tyre like the PS4 S will make those lists time and again which says to me it's a good tyre but it's not the only one.
