Might also check the valve stems - just got my car back from the 10k service, and I always check everything afterwards. Only thing holding air in the rear driver's side tire was the valve stem cap screwed on tight. When removed, constantly leaked; tightened the valve core (the spring-loaded thingy inside the valve stem), leak stopped. I checked the rest of them and all were loose, as they were on my spouse's Q - never checked from the factory (if you replace or tighten the core, just snug it up - it's easy to strip the threads - and if you replace it wear safety glasses, because it will depart the valve stem vigorously when you completely unscrew it). I check them all routinely now - a valve core wrench is cheap insurance.

Anyone gone from the 285 to a 275 tire? Looks like the possibilities open up as far as manufacturers etc

4400 lbs of car will do that.
And then some. 4900+ lbs to be precise. 4400 is the curb weight of my SQ5.

Indeed, looked to quickly. 4400 lbs is the towing capacity. Depending on the trim the Q7 is 4700-5000 lbs. It's quite a tank and will chew up tires for breakfast.

7700 lb is the towing capacity of the V6. 4400 for the 4.

I picked the number up from the model homepage on audiusa.com. Didn't read carefully enough and thought it was the curb weight. To get all the right numbers you have to drill into the specs for all the trims. Point is, it's a heavy machine that will eat tires and any issues with suspension etc. are just that much more compounded by all that weight.

20" pirelli scorpions.
I also have Pirelli's RF 20's and started to hear a rhythmic sound at 13k. The line service managers in two locations drove the car with me stated its the Tire not my car. One location brought me into the back and should me the alignment on my car was perfect - Post force balancing. and... i rotated the tires every 5 k

Anyone knows if Conti or Michelin are coming out with a RF for this size / dimension ? Rather not have Non-RF's as i drive on open roads Early or Late at time's
I had heard Good Years are not much better
Thoughts ?

yeah, I found the oem valve caps are lacking, bought some TPMS valve caps off Amazon.
