I just picked up an '06 Cayenne Turbo. It came with 22" wheels on 285/35 R22 wheels. I love the look and plan on keeping them, but obviously this setup won't do well off the pavement. I'm probably the very small percentage of Cayenne owners that will be taking their Pepper off-roading and using it to it's true potential. I'm running into problems with finding the right off road wheel and tire combination with some good all-terrain treads. I'm currently looking at the Nitto Terra Grapplers with some aggressive tread. Which setup will fit without rubbing issues?

Stock setup: 275/45 R19 overall diameter: 28.74 inches
Current street: 285/35 R22 overall diameter: 29.85 inches

proposed off-road setup
setup 1: 265/50 R20 overall diameter: 30.43 inches (my preferred choice)
setup 2: 255/60 R18 overall diameter: 30.04 inches

Is anyone running any one of these wheel/tire combos?

Thanks for all your help...although I predict I won't get much responses since it appears the Cayenne isn't really geared toward an off-road crowd like the Range Rovers. Even if there isn't much off-road support for the Pepper I'd still pick it any day over the RR.

 

You should take a look at the set up on the competition TranSyberria models. I think they ran an 18" wheel but I don't remember. Do a search and it'll come up.

 

I dont remember exactly where I read it but Cayenne were not designed for off roading nor serious snow driving. Thats why you would never see a Cayenne ad doing either.

 

not true, they are pretty good off road if you put them on the right tyres + wheels.

 

Of course but its not a "recommended" use

 

Please tell me you're kidding? The Cayenne has all the goodies to go off-roading. It's just that the people that buy them don't utilize it's capabilities to its potential. Come on... the Cayenne has variable traction control that constantly monitors wheelspin and redistributes torque to the appropriate wheels, it has center locking differentials, air suspension with variable ride height to improve break over, approach, and departure angles, etc.

Here's a video on it's capabilities. Please do your research before you make any false statements. Thank you for your input.

 

these things were tested in extreme conditions and were put through some abuse before production. the transyberia models were very reliable and fast. saw it when they actually showed it on t.v. check out their specs, I know they're somewhere on the website, also past excellence mag. this car is very capable of going off road. You ever see BMW racing their X5?

 

I am not saying the vehicle is not capable. As a matter of fact properly equipped I think it can take on a RR any day. However, Porsche will tell you the vehicle was designed for performance not offroading.

 

255-55-18 is the original size for 18" and it is a somewhat common size so you should be able to find few all terrain tires for it. I know General makes one, it is cheap and good.

275-45-19 is what I have on mine, it is an odd ball size. I am not aware of any AT tires for this size. And I would assume it will be even harder to find AT tires for 20" & up that will fit the cayenne. Anyways, for offroading use, 18" is the smallest wheel that will clear the caliper. (17" for the V6 and 19" for the Turbo S)

Also, if you scroll thru the PCM, there is a list of tires you can select. Talk about easy speedometer calibration!

 

Where exactly do they say that?

You sure you aren't thinking of the x5?

 

 

The main reason the Cayenne weighs as much as it does is because of all of the off-road ability engineered into the chassis and suspension.

 

Thanks for this info. I will definitely consider this setup.

 

he has to be thinking of the x5.

 

yeah the cayenne is primarily known for it's excellent off-road capabilities. in 2006, for the first time a cayenne won the Transsyberia Rally, a race from Moscow to Mongolia across some of the roughest terrain on earth. the rally is open to all 4x4 vehicles that are street legal including going up against several range rovers. the following year in 07, the top spots from first to third place were all driving cayenne s'. then the following year in 08, cayennes clinched positions 1-6.
because of cayenne's success in the rally, porsche made the cayenne s transsyberia edition.

i think in the next one.. something like 80% of the teams in the race are going to be driving the cayenne s transsyberia
