265/65 R18 BF Goodrich All Terrain on 09 GTS
Does anyone know if the 265/65 R18 BF Goodrich All Terrain T/A KO tires will fit on a stock 2009 GTS? The overall diamter is 31.7" I did several searches and did not get a definitive answer.

You might have to get your dealer to tweak the electronics with PIWIS to be sure that everything is in synch with the larger tire diameter; but they should work.

Has anyone fitted these 265/65 R18s to a stock 2003-2007 Cayenne S? There seem to be several threads stating these tyres were used on the Transsyberia rally cars but nobody seems to say yes I've done it.

what i'm interested to know is if the computer will figure it out and compensate for speed readings. Definitely let us know how you fare... because I will definitely go that route myself. On my ML I have gone with larger diameter than stock and feel the like the truck got way more useful with the fatter tires.

Hello everyone! This will be my first post to the forum. My wife and I just bought our first Porsche, a 2005 Cayenne Turbo, about a month ago. After perusing the various forms I took the leap and bought a full set of 18 inch stock wheels and installed 265/65R18 Kumho Road Venture AT51 all terrains. After one challenging but damage free excursion up a little used, overgrown, rocky forest road here in the western Cascades and a few street miles I can report no rubbing/clearance issues with the tires.
On a side note, this trip confirmed my long-held desire to get a Cayenne. It's a thrill to drive on the pavement and a very competent off-road vehicle as well.
Eagle Creek Rd., Mount Baker-Snoqualmie National Forest, north of Skykomish, Washington.
Highway 2 is 3000 feet below down in the bottom of the valley.

Sorry missed this thread, to be clear I run 265/65/18s BF goodrich A/Ts on my 2009 GTS. No issues.
Note when Air suspension is fully down (failed) they will rub, but in all other scenarios they are fine.
Tons of pics here. www.facebook.com/CayenneGTSoffroad
There is a post when I put the wheels on, must dig it out.
They are great on trails, average on sand in my limited opinion.
PS - love the pics above. Cayenne getting used properly - Like it!!! :-)

I run this size on my CTT and mine doesn't rub even on load level, but the speedo does read really low. Basically if I indicate whatever the posted speed limit is, I'm going fast enough that I stay with traffic.
I don't bother to try and learn how to recalibrate the speedo since I have another set of 20" tires that are accurate for speed, but does anyone know how to do it? With durametric maybe, if we are lucky?
I know how to calibrate the GPS for new tires on my 996 but I don't think it affects the speedo?

I checked with my local independent Porsche shop and unfortunately there is no way to recalibrate the speedometer on my Porsche Cayenne to match the oversized tires. I just adjusted the tire setting to "All Season" and "255/55R18". From my calculation the speedometer is reading about 2 mph slow at 30 mph, 5 mph slow at 65 mph 6 mph slow at 80 mph.

Porsche Cayenne S 2011 hybrid
Hello everyone. This thread has been very informative as a reference before adquiring a new set of BFG tires.
I have a Cayenne S hybrid 2011 and would like to get the 265/65/R18 setup, but I've yet to find someone with the same car, try out the BFG setup.
Is there a difference between the 09 turbo model and the 2011 S model, regarding spacing between the wheels and fenders?
We presented the tire against the space, and by the looks it might make contact with the fender.
