Tire pressure on 275/30/21 on RS7 with Pirelli

[hverkoff]

What are folks running their tire pressure on the Pirelli's 21?

I'm now keeping mine as recommended on the door jamb so mid 40s cold, without walking outside I think its 45. I had a sensor go off for low pressure so swung by the dealer last week and asked what they thought after seeing all of mine were in the mid 30s cold. They said that Audi directed them at delivery PDI to lower the pressure to around 36 cold to be more comfortable for folks...that's where mine was... if I wanted 'sporty' to put it at the higher pressure...I had them put what's recommended on the jamb. Since your roads are pure hell having lived there in Chicago and was just there on business and nearly killed a wheel on my rental the lower pressure may be better but personally I bought my RS7 to feel like an RS car so stiff it is....but my roads are smooth.

Running mine at 45 all around. I played with some different pressures and felt like the higher pressure felt best in terms of steering without much difference in ride quality. On a side note, I I've got about 3500 miles now on them and feel like the road noise is about twice as load as when new. Anyone else notice this?

Running mine at the pressures in the manual. Car was delivered with 45 cold all around, which I believe is the max load pressure on the door jamb. I lowered them to the manual numbers to improve ride

I think 45 psi cold is too high and is, as mentioned for full load, so I run 39 psi on my 295x30x21 PSS tires.

I run 41 or 42 all around

[TheChef]

I run 41

Actually the 2015 manual states with 2 people in the car the pressure should be 41 front and 38 rear. With full load it is 45 all around

45 front and 42 back usually. Rides fine.
