where are the Porsche cayenne expo builds?

What did you do for a spare?

I tell you . . . there's always someone around to squash your brilliance. :sombrero:

I do have the factory blow up spare, which will give me a tire, but I haven't yet done the test of seeing what the computers think of the diameter mismatch, though limping somewhere at low speed will likely work. This, along with a AAA membership and a cell phone, is Plan A, obviously best used in civilized areas.

Plan B is that I have a tire repair kit and onboard air. I know how to plug/patch a repairable tire and will have air to blow it up.

Plan C, to be implemented if I'm going somewhere where a sidewall tear or similar would be a serious problem, involves deploying the mesh Rhino Rack I own onto the factory roof bars and strapping on a spare on a suitable rim.

It's very early days on this setup, and maybe more serious ambitions will develop, but the Cayenne was chosen because of its superior long-distance pavement abilities, with the ability to go off-pavement being a secondary benefit. So unlike some, I'm unlikely to take full advantage of the truck's off-road skills. I have a genuine off-road truck for serious stuff, so I was working to get the Cayenne to be workable for BLM/Forest Service-type roads without a big hit to the pavement goodness.

Also, plans B and C would be backed up by my Delorme InReach, which goes a long way toward keeping them from finding my bleached bones in the desert should I have tire problems. Realistically, I probably won't be using this truck anywhere I couldn't get timely help, and I don't expect to turn stupid about where I go, but a satellite communicator is an easy way to have backup and enhanced piece of mind.

have you looked at the beginning of this thread and see my solution?

Or search my mep1811 and see what I have done .

Nothing replaces have a full sized spare when outside of AAA, cell range.

I would not want to take any chances with the diameter regardless of the speed or distance. I am surprised YOU would even consider this as an option at all. Just toss a full size spare on it's roof or some hitch mount. I carry a full size in the cargo space of my BMW 5 wagon! So, you can do it too!!! Your "A" option sounds like a nightmare day to me. How exactly is AAA going to play out even if you are within 200 miles of a town with a tire shop or dealer? I'll tell you how, likely a long *** wait for the haul, then a worthless hotel night. All for what, to not just be self sufficient?! I say this with exclamation because I've been there once for a tire issue and once is enough with how it disrupts a trip.

In my BMW which has a similar amount of total cargo volume but a lower interior floor to roof height, my full size fits perfectly upright against the left side of the cargo wall behind the backseat but I usually have the seats flat for better loading space. I use two heavy duty ratchet straps that tie into the frame mounted cargo and seat lock loops. The strap makes two loops around each tire section with one high and one low. Having the inner wheel cavity facing the cargo area and the two straps running across it at different heights also allows use of the space inside for a small pack or other items.

For camping trips, in front of that tire on the flat folded 2nd row seat sits my 37L ARB fridge I love road trips in this car only missing what you have in your "soft-off-roading" capabilities and towing. This is an E61 6 spd with rear air springs for "load leveling" so I can really load it up while retaining handling but not like you can with the PASM and PDCC combo! I bet that's really awesome although I would have gone for the tdi or GTS for smaller brakes. I had a VW V10 tdi with 265/65x18 BFG and that was really sweet.....wish I'd kept it.

Hey Mike. I don't visit the P-Car threads very often. Back in my P-Car racing days, way back, when it was actually better to upfit an old car with modern goodies like engines and brakes, we all had the problem of fitting the huge turbo brakes on the cars (as you know the secret to going fast is to be able to stop fast). The brakes required large rotors, and the large rotors required larger wheels. But you know that as you sit with your 19's. Just curious, to finally get to my question, did you consider a smaller brake/rotor set up with smaller rotors which would allow for a more offroad beneficial wheel and tire set up? I would think that you could get the same overall size so as to not confuse any of the computers (ABS, traction control etc). Assuming of course that you are not going to be pushing the car on pavement enough to take advantage, or need, the huge stopping power that is available with the stock setup. Just wondering....thx.

You're right. I'm an idiot. Don't know a damn thing about what I'm doing. :sombrero:

I'd previously avoided posting on this thread as I'm not engaging in any serious Cayenne off-roading, but given all of the difficulty I had finding information as to what wheel and tire sizes would fit on a Gen II CTT, I thought it'd be good to get my findings recorded on the interweb. And now, my work done, I depart and leave you to your adventures.

It's not that I'll need Turbo-level stock braking, but it's not worth messing with it . . . the off-pavement use doesn't warrant any special efforts, and keeping the pavement performance is a higher priority. Given the cost of fixing damage if I screwed up, the "trails" I'll be undertaking will be well within the capabilities of the 19s. Not really worth doing anything to make this a serious off-roader.

Wise. I expect that my 'simple' idea would cost several thousands and may not even work. I'm good at stuff like that.

Nice clean set up Mike!

Thanks . I know a little about Overlanding. This is my usual Overlanding set up.

I hope you didn't misunderstand me. I was complimenting you on having a knowledge base that would supersede any plans for using a doughnut spare tire, anywhere, anytime.

Seems to me with several good 20" tires available these days, and room to fit something in the 31.5-32" range, you could just go with a solid tire and full size spare to just about anywhere you like. It's pretty cool really how Porsche made such an awesome handling "car" also so "capable".

I just noticed you opted for the 6 spd! SWEET!

I drove one the first year your generation was out and found it to be a lot of fun. Plenty of "go" possibly made fun enough by choosing the gears, not sure, but it was nice nevertheless. I have thought it would be pretty cool, and very rare, to build/order a 6 spd decked out with PDCC, and everything, the 18 way seats, heated windscreen, etc. but it had better be a keeper because nobody else would ever pay what it's worth

Do tell about your wheels and tires though. You appear to have 18" AT's on the ground but a non-matching wheel and street tire on the spare mount.

Not that you asked anyone for opinions or suggestions but.... your choice to put the fuel that far out the rear cannot help with handling. I'm usually not a fan of heavy things on the roof but in this case I'd rather have it on the roof and forward rather than way back there and it's up pretty high too considering it's not on the roof. Same for the tire. That hitch is not helping with the departure angle. You surely have thought of this though.

Also, I know the Rotopax are cool and all, I have two for water, but they can leak. Nothing works as well as a true welded jerry can and frankly speaking, they're easier to use for cars. To me Rotopax are more ideally suited to adventure bikes.

Places like Expedition Exchange carry the best jerry cans. Some other place is again now but I forget where/who.

Anyway, I envy you Cayenne trail runners Probably when my bmw wagon is gone it'll be replaced with something like what you guys have rolling.

The company that made my spare tire carrier originally only made it to carry a high lift jack. I asked them to make a Roto pax carrier as trying to mount a Scepter can would simply would not work and keep things tucked in.
Tire and wheel choice was based on cost. The tire was the same as my OEM tire and I'm not going to get rid of a new tire so everything looks the same.
I've been doing this for a very long time and have a slight idea what I am doing. )check my above picture) I'm not doing any technical stuff and the slight overhang has never been an issue.
I have a steel suspension and a spacer lift from Germany in the shelf. That should give me a 1 1/2 lift.

The six spd is great and it was extremely difficult to find a dealer to order me the car I have. I believe I have the last one imported to the US.
