U guys are great!

Thanks so much for the feedback! My understanding is that the 2014 Cayenne towing weight is still in the 7700 lb range. The TW, however, is only 600 lb.
With that said, is a 25' international, with a MUCH larger TW, still a possibility?
I had read somewhere that it was the same vehicle...Porsche, of whatever reason, downgraded the numbers to 600lb. So will insurance companies, being that they will find any way not to pay a claim, demure on paying a claim of you tow outside the "recommended " range? Regardless of the tweaks someone like CanAm can do?

Go to that other linked Cayeene/Touareg/Q7 topic, since some folks on there have already talked about how they lowered the tongue or hitch wt. on their AS to fit that limit.

There's really no need to carry 30 or 40 lb. Propane tanks for example - since it lasts forever anyway (or 2 - 30# LP tanks were still 1/3 full since the PO filled them in 2007, when I pulled them to paint silver & filled while dismounted). Aluminum tanks are also lighter than steel, etc.

You can also relocate batteries & some other things to reduce HW on an AS, plus some models & their sub-configurations are less GTVW & HW than others.

You need to go up a few posts & hit that link I already gave you.

PS - for your own safety & proper handling/towing, you'll wnat to work it out within the specs - regardless of what insurance companies will do!

And the CanAm tweaks on strengthen the hitch & help transfer the wt. forward, but not increase the HW or TW capacity (although one wonders why Porsche adjusted it lower on the Series 3 Cayennes - CYA?).

Good Reading!
Tom

Popcycle...I'm likely repeating others above, but we are towing a 27' EB with a 2011 Touareg TDI with a WD hitch set up by CanAm. No issues whatsoever though we haven't been to any mountains yet only hills with 7% grades. Very comfortable towing and we take our time, not ever above 60mph and getting about 15mpg. I've towed a fifth wheel and hitch with a dually 3500 diesel and this felt better, or at least as good.

Question Question on Towing with Low Profile Tires?

What are the collective's thoughts on towing with a Euro SUV with Low Profile tires & upsized wheels - is it safe, too much stress on tiny sidewalls, etc.?

We looked at a nice 08 Cayenne S last weekend with upsized aftermarket 22" x 9.5" alloy mulit-piece wheels with 285/35R22 tires (max. Porsche wheel for Cayenne is 21"), but I'm concerned about how well those low profile UHP tires will stand up to the stresses of towing - aside from them riding harsher, wearing out much faster & the fact that the aftermarket wheels (which make I cannot i.d.) may not be up to Porsche spec nor the towing task.

All I can say is - IMHO- it's pretty lame what some guys will do for an extra inch! ;-)

Your sage input would be appreciated.

Cheers!
Tom

mhony - what kind of life are you getting out of your tires miles/years?

I don't know what the profile is on your truck's tires are, but they may be taller than those 35 profile tires on 22" wheels which I saw.

The ones on this Cayenne at 285/35 may be much shorter than those on your Toyota Truck, from what I've seen on Tundra's locally.

On the 2008-12 era Porsche Cayennes that we're looking at, they had a choice of 4 wheel sizes - & all are cast or forged one piece aluminum construction:

18" x 8J wheels with 255/55R18

19" x 9J wheels with 275/45R19

20" x 9J wheels with 275/40R20

21" x 10J wheels with 295/35R21

>

Whereas - the aftermarket alloy wheels which I saw are an undetermined maker 2-piece allen bolted rim/center at 22" x 9.5" - with 285/35 R22 112V XL UHP tires.

Best!
Tom

As the truck is a 2007 with 51,000 miles, I have replaced the tires once- not due to tread wear but dry rot-
I got new tires at 35,000 miles (7 years) in the spring of 2014 because the original tires were cracked on the sidewalls. There was still plenty of tread left.

New tires (2 years old, 16,000 miles) still look good.

You are correct about the tires being taller. The aspect ratio is 275/55 for all Tundras with factory 20" wheels and tires.
I wonder if a shorter tire is better? More stable? Less sidewall flex?
I couldn't imagine that it would matter much if the tires were 35, 40, or 45 series.
Ask CanAm!

When I bought the Toaureg it had the 19" rims with low profile tires. I swapped the 19" rims for 18" Audi rims mostly due to more options / better price for tires. Since the VW only has an inflatable spare, having good access to a replacement tire was also a factor. Aside from that, I hate the ride of the low profile tires.

I imagine 17's or 18's would ride better.
I also think they would be better for towing.
That being said, I did not know all that at the time I bought the truck with factory 20's.
Maybe next time...

m.hony -

That useful life sounds pretty good. I too had to replace all 4 tires on both our 85 BMW 325e & 88 VW Westfalia last year due to age cracking not wear (both were 75% or more tread), but we only put 2-3000 miles per year on each, so it's the age that gets them for us.

Also your 55 profile taller sidewalls would ride better, while the UHP lower profile 35-40 profile tires will be more susceptible to road hazard damage (both rear tires on the CayS I looked at had sidewall splits, but with decent tread) - in addition to being rougher riding due to less sidewall flex to cushion the ride, but they will generally handle better in everyday driving (i.e.: not towing).

However, the 22's with 285/35R22 tires has a 2-4% error over the 18", 19", 20" & 21" factory options I listed above - so both speedo & odometer will be off, & there will be that much "phantom miles" on the car due to the upsized wheels.

.

Truckin -

I did see that, on Tire Rack at least, there are far more choices in either 18" or 20" sizes, & 18" & 19" have more cost effective options than the bigger tires - but I'd probably try to keep with the OE or OEM similar tires with Porsche's N-spec tires if I can, so those are a bit more.

If we move forward with the CayS with the 285/35R22 on 22's, then I would look around for a set of factory size OE Porsche wheels & tires to trade/buy & swap out.

I'd also always planned on getting a 5th matching wheel/tire as a spare to take when towing & long trips not-towing, in whichever factory wheel/tire size was on the Cayenne, based on other folks suggestions on here & RennList Cayenne Forums - along the lines of your recco above.

Thanx to you both for the input so far!
Tom

I'm the orig owner of a 2006 Cayenne S with air suspension, am just retired and my wife and I want an AS. She likes the Flying Cloud 23D but it has a tongue weight of 720 lbs. My factory tow package TW is limited to 616 lbs per the sticker as well as the owner's manual (others have stated the limit is 770). So how is it that others have TT's with higher TW's and are doing just fine? I don't plan to do the CanAm mod or add a WD hitch as that ups the TW (albeit with better sway control).

Also, others have said that Cayennes with air suspension won't benefit from from WD since the system will automatically level the vehicle. Comments?

Dave

DS, you need to do some additional research. 1) Towing without wdh is a very big decision. Many do, but understand all of the pros and cons before you make the final decision. 2) The air suspension does not address returning the weight to the steering wheels. It just raises the pivot point. It may not be necessary to transfer weight, but you need to investigate and determine the validity of your configuration. 3) Choosing the AS model to match your current vehicle may not be your wise move. Changing later is expensive if you get it wrong. Decide what you want. Decide what you need to tow it. Then reconsider the package and your budget. 4) Payload is a significant consideration in addition to reviewing tongue weight. The balancing of those two loads is somewhat variable and may help you achieve your goal. But the starting point is understanding what gear you will carry and how you will load both the trailer and tow vehicle. 5) The capacity listings for German vehicles have a lot of questions raised. Experience seems to be very good for those owners that choose these vehicles. However, they do often consider hitch reinforcement for heavy tongue weights. The published tongue weights for ASs are under stated in most specs as when loaded for camping it will be 2-300#s more. It's worth looking at the threads that address actual tongue weights.

Two final comments. The dump valves on the 23s are close to the ground and not protected. They can be damaged when the rig transitions driveways. The 23s are fitted with 10 in brakes, 14 in wheels, and 5 on 4.5 BC hubs. It's problematic to upgrade these components, but there are solutions and you should understand your options.

Good Luck with your investigation. Pat
