Two months ago, my n/s rear tyre went flat. Half run in, there was after examination at the tyre shop a noticeable bulge in the tyre wall and so was scrapped.

So feeling unlucky I had it replaced. Today with barely a few thousand miles on that tyre, I have another flat on the same tyre.

Is there something I should be aware of or am I just unlucky?

My vRS is running the standard 16-inchers, 45 profile on sportcontis

Just unlucky dude.
