Q7 Tire Pressure
Checked the tire pressure label in my Q7 for the first time today. Front - 44 PSI; Rear - 49 PSI.
Wow, is that high! I've owned over 30 vehicles, and can't remember any of them having such a high recommended cold PSI. Even my full size GM SUVs were just 35 PSI.

Yes, it's nuts.....
Yes, it's nuts, isn't it? Talk about a rough ride..... My 07 Q has air suspension, and after trying recommended pressures once only, I've always run around 36 psi (275/45/20 all season Continentals). This gives a good balance of comfort, handling, and tread life.

I have personally found that 42 psi maximizes tire life and wear but also provides a good ride.

I noted the manual says all 4 tires can be set to 35 PSI for "comfort", provided my typical load is me plus 2 passengers. They should be set to the higher pressure if I have a full load.
In either case, I must update the MMI to reflect the current pressure I'm using.

Thanks. I didn't think to research the manual, as I'm used to relying on the door sticker.

Some peole don't like me to post here any more as I am not an Audi Q7 driver/owner any more (MB E350 now) due to severe issue with the dealer and AoA but I'll post anyway.
As my Q7 turned out to be the worst rattle box I ever owned as a vehicle to drive I also tried to lower tire pressure. The car came with factory installed Continentals. I tried to lower tire pressure and it helped a little bit but it also caused severe tire wear at edges. I drove with 35 psi for a couple of thousands of miles but after seeing what it did to the tires I raised it up to 40 psi. This did not stop edge wear on tires, slowed it down some though.
To make your tires to wear evenly they need to be inflated to the pressurer Audi actuaaly knows to be the right pressure. It does not matter what some BRAIN WASHED Audi lowers want you to believe. A car should be able to drive confortably with tire pressures that provide even tire wear across the thread. On Q7 this is a far fetch including the air suspension ones.
