Bridgestone S02s, Pirelli PZero Rosso and Pzero Assymetrico, Continential Sport Contact 2s and some Yokohamas are certified for Porshe 911, according to the Porsche Magazine I was reading the other day. So just because something is OEM ona Porsche, or any car, for that matter, doesn't make it automatically the best. Alot of top performance cars are tuned to a particular tyre, so it can sometimes pay to keep to the same type. Eg, Honda S2000 runs on special S02s, Focus RS runs on special Michelin Pilot Sports.
Chris, Bridgestone is Japanese and owns Firestone, which is a strong brand in the US and produce a lot of tyres there. Their top tyres are made in Japan, the lower ones are made all over, with some local. Firestone has/had a strong relationship with Ford, until the rollover court cases. Ford basically created the Firestone empire.
Michelin is French, and own Roadstone and BF Goodrich. Roadstone is their cheap brand, and BF Goodrich is being marketed towards enthusiasts, drag racing, etc, and is a strong brand in the US. All of their top tyres tend be made in France and the US, with a lot of their lower and middle range tyres made in Thailand. They're currently the #1 tyre company, measured in sales.
Yokohama is Japanese and own Nankang, a very cheap brand. Advan is their "Potenza" competitor, it's a branding to represent their performance tyres. I don't know where their lower tyres are made, but their top tyres, are made in Japan.
Dunlop are Japanese and own Sumitomo (I'm pretty sure, have had my doubts of late, but there is a Sumitomo Dunlop website, which shows a close relationship). Their top tyres are made in Japan and Europe. Their lower tyres are made locally.
Goodyear are American and are the 2nd largest company. They produce tyres in Europe, US and Australia. Their top tyre, the Eagle F1 GS-D3 is made in Europe.
re: Bob Jane All Rounders,I would imagine they are outsourced to Dunlop or Goodyear locally to their own specs.
