OK. Just to clarify the Millenium - Cooper thing a bit.
Cooper, the second largest American owned tyre company (after Goodyear) bought Avon's tyre business in the late 1990's (ish
).
As far as I can determine, the "Millenium" tyre is made in a German factory but you'd have to look at the sidewall of one to confirm that. And yes, Millenium is a sub brand of the Cooper-Avon conglomerate.
FYI, the other two large "American" tyre companies , Firestone and Goodrich are now owned by Bridgestone and Michelin respectively.
