Conti Sport Contact 2's.
Front right wore down to 2.3mm tread at 30,000km. It was even wear across the tread.
Front left still had 6.5mm tread of the 8mm tread depth on a new tyre. For the first time ever I replaced only the one tyre not a pair.
Rear tyres still have average 5mm tread remaining.
I can't complain, but I don't know why one tyre wore more than the others.
PS. Contis are "Engineered in Germany" but have manufacturing plants in a number of countries.
