I have a set of 235/45zr17 Dunlop SP9000 underneath my 1990 300SL-24 and have driven them approx. 7000km last year (lots of #*ck#@! bad weather in Holland).
The tires are good but do not last as long as the 17" Pneumant's I normally have on my C250D.
The Dunlops are doing very well at high speed (250km/h) and do not make that horrible noise most tires make whilst braking after these kind of speeds.
The tires' contact with the road is good and the tires do not squeal in (ocassionally)high speed turns/bends.
The biggest disadvantage (besides the rapid wear of the tires) is that the tires get square after the car isn't used for several days (lets say 14 days). After the car is parked for a 2 weeks, the tires have a flat side and I find this highly irritating. The tire will round up again after a 100km, but this is something the car should not do.

We had 16" Dunlop SP9000 on a SLK230 as well and they only lasted 16000km!
Normally I have Pneumant 215/45ZR17" tires underneath my C250D and these tires last for 50-60000km (third set of tires already!), even though the car is lowered a lot.

Mickey, what do you mean with European Delivery...did you pick up your car at the factory, or...

greetingz,
