Actually, in this situation he did not reinforce that hitch but cautioned that he would normally have done that. I believe he stressed that he used a WD system with torsion bars that had lots of travel to minimize the forces acting on the vehicle frame. This specific situation was not the ideal set up. More interesting reading here which addresses some of the conversation above...

I think CanAm does quite a bit more than just reinforce hitches when they set up a customer vehicle.
If they had reinforced this one, wouldn't the justification be that the stock hitch was rated for xx, and they wanted to strengthen it to handle yy to ensure their was sufficient tongue weight? This considers that the setup would be based on remaining within the published axle weight ratings. It isn't a vehicle reinforcement, it is a hitch receiver reinforcement.

What about those Continental tires?
Hey, have we argued about those tires yet on those fancy sports SUV's pulling an AS trailer? Are they rated for towing or does it even make a difference if you tow with speed rated tires? Seems to me, that discussion is important also? Not to stir the pot!

It's a slow morning so I'll bite:
Continental Extreme Contact 275/45 ZR20 110W XL. The 110 is the tow rating and the W is the speed rating. Using this handy chart from Tire Rack Link you can see that a load index of 110 corresponds to a load capacity of 2337 pounds double for the second tire and you have a tire load capacity of 4674 pounds on the rear axle which is well above 3693 pound rear axle max load capacity for a Cayenne. Speed rated tires are fine as long your tires have the proper load rating for your towing requirements.

Most of the performance tires that come with Touaregs & Porsches are a soft compound that work great speeding through the corners but wear fast and tend to pick up things like nails and screws.

Mike - I never said that anyone should exceed the rated limits for any TV just because they had WD, nor on the CAy/Treg/Q7 trio.
I said that the hitches do in fact state a WD rating, which means that you can in fact use a WD hitch within the stated limits.
"by Mojo:
Towing weight on Touaregs has been 7700 lbs since 2004, regardless of whether it's a V6, V8, or V10, gas or diesel, even though GVW are different. Hitch design and weights are different in Europe, which is suggested at 8% of tow weight, which is 616 lbs. In US, suggested hitch weight is 10%, or 770 lbs on Touareg. I called VW NA and they sent me a hitch weight sticker that said 770lbs.
But believe and do what you want. After 8 years towing with a V8 and a V10, I never lost a hitch using just the ball and/or a hensley."
Also as MoJo said about the Tregs with which he's towed, the Euro & USA hitch stickers are different, because the German TUV (like DOT) has their standards which the EU recognizes, & the USA has the SAE standard which DOT recognizes.
All Cayennes except the Hybrids have also always been rated at 7716 lbs, & 770 lbs HW - & you can contact your local Porsche dealer for the USA DOT sticker, as Mojo did with VW.
If your Cay was factory fitted with the hitch, then it would often have the Euro sticker, while those who had the P-dealer add it or buy it from Porsche parts, then they'd likely have the US-DOT version.
As for tire & wheel sizes, most prefer the 18-19" rims size for comfort, grip & those who off-road, while the Ricky Racers of the world seem to prefer the 21-22" wheels with very low profile tires & the resulting harder ride, your 20"ers are in the middle of that.
I'd be interested in hearing what you think of 20" vs. your other 19" ones after awhile running them!
Cheers!
Tom

The Porsche N-spec tires for the Cayennes & Macans are rated for towing (unless stated otherwise in the specs, e.g.: for track oriented tires), per the "official" Porsche Engineers at one of our SoCal PCA PCNA/Porsche AG Tech sessions.

Kevin,
Just about a week ago, I too did post that article, as well as the Porsche Cayenne TDI one & a few others relevant to this discussion of P/A/V, BMW & MBZ SUVs, WD, Sway control etc. at post #447, as well as early in this now long topic.
http://www.airforums.com/forums/f463...ml#post1929736
If you want to read up on the others....
Cheers!
Tom

Tom, that was Ohiobrits who switched from 19 to the 20 inch wheels. I doubt he'll notice much difference in ride quality except the fact that he's not on winter tires anymore. My Turbo S came from the factory with P275/40R20's and the air suspension is sport tuned. I'll be honest, its stiff and just a little bumpy. Not 911 bumpy but nowhere near as smooth as my Avalon. A little more sidewall would be nice driving around town.

I like the wheels! Same story with the factory Continentals on my ML350. Blow out on I80 middle of the night 50 miles from Iowa City. Less than 20k new Michelins the next morning. Big difference in overall feel and ride.

I can't edit this link into my post above this late, so here is the link to the page for the Porsche Tire Approvals, just click on Summer or Winter for the pdf file, then look for your Cayenne, Macan or other model (there is a similar list in Porsche's Classic section for the older model, like my `73 914-2.0 "914S" - in addition to what is on here).
http://www.porsche.com/usa/accessori.../tyreapproval/
For VW Tiguan/Touareg, Audi Q5/Q7 owners - there are separate "Spec" for Audi (not sure about VW), but the Cayenne list will give you a good idea of which will work on yours, although you could probably buy the "plain ole non-N Spec" version of the same tires.
BMW & MBZ have their spec tires too I think.
I'm surprised at all of the Conti failures on here from Cayenne owners, since they used to be top notch tires!
Although, I know many of our Cayenne owners out here have said that they wear fast on the Cayenne, due to the softer compound - so checking the "AB" wear code & "000" tire compound softness rating will help foretell how well they'll wear - the lower 000 number, the faster they'll wear.
I'm assuming that MsTara's Macan S tires were N-Spec, since they were on since new, as I understand it - so it's the soft compound = fast wear issue.
Out of curiousity - were the Conti's which failed, as in blow out, the N-Spec Porsche version, or the "plain vanilla" version?
.... or other applicable car makers' Spec for the MBZ, etc. failures?
If the plain version failed, then that makes me think that it's worth the extra cost for them.
Cheers!
Tom

MsTara gets a prize, less than 1000 miles and my first puncture. Tire was a total loss due to the location of the hole. The TPMS alerted me to slow down which I'd did very quickly - it was leaking fast. Had to find a 275/45 ZR20 with sufficient load capacity - on a Sunday. All worked out OK and got back on the road in a few hours but not how I wanted to spend my morning.
Then some idiot hit the back of the AS - minor damage only - but that's another story.

IMO worth to have tire insurance with such wide tires. I get mine from America's Tire ($40 or $45 per tire), even though I did not buy tires from them (275/20 front, 325/20 rear).

I am so sorry, not something I wanted to be right on. All 3 of my continental had zero repairability due to the internal damage, they all were torn up inside.
Please note that the Porsche has N rated tires and they have had to be special ordered for me each time. Discount tire and their insurance is amazing, but I had to tell them I wanted the N rated tires as not everyone is trained on the Porsce's needs.
Good luck and be safe out there.

Back in the good old days you would bring the flat tire to a gas station and he would plug it for $2. Today, they tell you you a new tire for $250.

Nowadays they put run flats tires on cars and try to convince people that this is safer and changing the tire is rocket science. Some are buying this, some don't.

I have plugged lots of tires (worked in a gas station) but an internal patch is a better fix.
The reason for not repairing a tire is that either the puncture is too close to the sidewall, or there is structural damage from running under inflated. That damage isn't always visible so tire repair shops err on the side of caution.
I had a flat in a RFT on a Z4. Drove slowly to a gas station and inflated it. Drove to my tire shop near home. It was down to 20 psi. They asked how far and how fast it had been driven, at what pressure, and advised it was fine to fix. If I had driven straight there at usual speeds, they would have declined to fix it. Many owners think RFT means usual operation, and destroy the tire after the puncture. Also, some tire manufacturers are more conservative than others, they all have slightly different guidelines.

The puncture was within an inch of the edge of the tread on the curved area so the guy indicated it could not be repaired. Have a Mazzini fitted right now. If you have bad reviews I don't want to hear them. It will be coming off when I get home.
I bought the original Continentals from Tire Rack so have free Tire Hazard warranty. I'll call them up when I get back to see if I get a free replacement.
Made it to Gulf Shores today without further incident. Picture from the beach part way there today.
