There are different types of SP9000 tyres available. There is a version for the Lexus IS200. This is the reply I received from Dunlop about the differences and how to tell the difference.
[quote]The biggest differences in the 215 40 r 17 Dunlop SP9000 for the Lexus are internal. The tyres construction is tuned to compliment the way the car handles.
The Lexus tyre is made in Japan while the standard SP9000 is made in Germany. Both tyres have stickers on the tread when new. They are removed when fitted. The sticker will say if the tyre is for the Lexus should it be the correct one. Should the sticker have been dislodged then look for made in Japan on the tyre.[/quote]
I will add this info into the knowledgebase.
