- there is NO Pirelli Wintersport recommended for the Cayenne
- Speedindex from 240 would be fine but 210 is the fact
- same with the size 255 not for winter, 235 is recommended
- there 2 (two) Grandtreks for winter: M2 & M3 (this only cuz you want it correctly - read your quoted post above)
- you can say what u want - Dunlop Grandtrek is the correct name.
Ok if you want confusion on the top you can also say its a offroad tire from Dunlop but its fact thats also the correct wintertire or the Cayenne. So, who is confusing here?
You can say glass is half full or half empty, right?
Again: you don't have a Dunlop Grandtrek on your Cayenne but a Dunlop Grandtrek WT M2 or M3.
This is the same if I'd say that I have a Pirelli PZero on my car...WHICH one? PZero Jiallo, Rosso, Direzionale, Nero, Corsa, Asimmetrico? All are completely different tires.
So let me see: there is a Dunlop Grandtrek SP9000, Grandtrek PT9000, Grandtrek PT1, Grandtrek ST8000, Grandtrek ST1, Grandtrek AT2, Grandtrek MT2, Grandtrek TG31. Not to speak about specialty Grandtrek off-road tires (I'd need the whole night to post the list). None of these tires is a winter tire. So do you really have a Grandtrek? It is like telling people you own a Porsche 911 but are the 911 C2 and GT3 the same thing? C'mon.
Dunlop changed the name of the Wintersport M2 & M3 for SUVs because ALL of their SUV tires are now named Grandtrek, the profile is the same on the Grantrek M2/M3 and Wintersport M2/M3.
You are right with one thing: the (official) information I have states Pirelli Wintersport W240 but in reality it seems that it is the Pirelli Scorpion Snow & Ice because I called Pirelli today and they confirmed there is no Wintersport W240 in the 255/55-18 size. And yes, the Scorpion Snow & Ice is a winter tire but only good to a speed of 210 kph. But I guess this isn't my fault if the documentation isn't precise.
I would love to give it up but I try again (maybe you'll understand): the information on Porsche's Tequipment site is not current information, the information I posted is the latest one. I'm sorry to disappoint you but the 255s I mentioned are winter tires and they are approved for the Cayenne. Officially.
Bad luck your dealer wasn't aware of it.
Or do you think I invented the official Porsche part numbers by myself?
And now I stop before I really get a heart attack.
