Brent 89-GT

I know a few guys running the Nittos in a 18" wheel size on the Mercedes G500's. I have even been off road with one wearing those tires. He had driven from Tennesse to Utah on them, off-roaded in Moab for a few days and drove home. I know he had tried a BFG AT prior to the Nitto's and liked the Nitto's better. Does the Nitto come in an XL load rating? I had my dealer tell me that they had seen some tires that were not XL torn up running on a the heavy Cayenne. I can't confirm if that is actually true but, the Cayenne is a heavy truck.

One thing to seriously consider is a spare. 85% of off-road mishaps are tire related. The compact spare wouldn't be much comfort to me, and fix-a-flat doesn't seal sidewall tears. If I you are going to be more than a couple miles from civilization and extra full size wheel/tire either on the ugly factory mount or in the cargo area would be a good idea.

Oops, I use Pirelli AT's in 235/60-18...

Load rating is important on the Cayenne. Nitto's have a load index of 109 on a scale of 71-110. 109 translates to 2271 lbs/tire at 50 lbs inflation.

BTW I agree the wimpy spare tire poses a risk for serious off-roading. To avoid this throw a full-size spare in the back. Of course then you'd have about as much cargo space as an H2. Be sure to pack a small lunch.

I am wondering if anyone had the chance to offroad with the advanced offroad tech pack?

I'm curious about that too.

Anyone?

I have it in my car but haven't had the chance to go off road yet! Stay tuned!

GM Austin

How long have you had it? Any problems?

My car is an 05 (Sept) and I haven't used it yet so I can't comment ..it doesn't interfere in any way with normal activities.
