Our 2006 Titanium edition Cayenne S came with 275 45 20" all the way around, can't find any reference in the owner's manual or on the driver's side door that tells me what the tire pressure should be. Owner's manual only reference 19" which asks for 38 for the front and 49 for the rear. I thought the rear is a little excessive.

TIA

I think the rears should be 42. Its 49 when the rear of the car is loaded, ie, towing. I put 48-49 when I tow my boat.

My '06 (non-Tit) has the TP sticker on the drivers door, I wonder why yours doesn't? I agree the 49 is high, on mine it says 38/42 moderate load and 38/49 max load but I have 18" wheels. I'll check if there's any info for 20's on mine.

Is there a TSB for Cayenne tire pressure? Might be worth a search. I'm sure you have access to the RennTech.org TSB info.

Update: Yes, there is a TSB on RennTech.org. It's titled "Approved Tires, Wheels and Spacers" dated April 9, 2007. It says the "partial load" pressure (summer tires) is 38/43 and max. load is 39/50.

38 43 is what I decided to put in last night. For some reason the previous owner pumped the fronts to 43...

Thanks
