19's or 20's max. On the fence. My x5 4.8is has 20's from factory and it rides a little rough. It has air suspension also.

Most likely titanium 19's.

I will say try 20s as they will fill the wheel arches better than 19s. I have 21s and yes ride is slightly rough. I put car in comfort mode on lower setting though...

BTW... Love those 4.8is'!!!

If I go 20's, I'm thinking matte black GTS wheels. I'm lazy looking for pictures but I think I agree, the 19's may be too small still.

I don't want to lose winter capability with the 20" wheels when we go up the mountain.

The 19 and 20's both have the same outside circumference ... but the 19's have more rubber and provide a much nicer ride. I have the factory spacers on my 19's in the rear and it makes a world of difference on the look.

I am running 20's on my Touareg with Nitto Terra Grappler. They are great in the Cleveland winters.

nice ride, congrats

The fact still remains that the Achilles heel of the Cayenne's acceleration response time lies with the electronic transmission software. I've had mine repeatedly tweeked by the dealer and although there was definitely an improvement over the factory preset, it still lags a bit off the line and when using the Tip.

The 928's Mercedes-Benz 4-speed auto shifts like a dream with zero lag and immediate response. There's no electronics in there that have to communicate with the drive-by-wire throttle, PSM, ABS and all that other hardware/software junk.

My $0.02.

For me the Turbo needs a coaxing, the GTS is always snappy off the line.

I have a 2004CT, and the lag was significantly improved when:
1) Dealer installed new firmware (done around 2005)
2) Ignition coils were replaced (done around 2009)
