I feel there is over half tread remaining. What should I expect on average as far as useable days with these tires in total. Car is otherwsie stock, nothing to help camber, etc.

These tires run for what feels like forever. In fact I have several sets of RS3's that are less than half used. Let me know if you need some spares since I have three sets of tires that I can't use stored in my basement.

Just ran a 2:23 on these tires at the Glen yesterday in Sport Mode. They have 11 Days on them. Was running 38 PSI hot. Still have decent tread left too.

I just put the RS4s on. Looking for cold PSI recommendations. Currently running 36F and 38R but they seem to increase rapidly after only short drives.

Check your tires hot too. I try to keep them around 41-42 on the track as they come up to temp quickly.

Start at 30 cold. Should come up to about 37-38 hot which should allow you to use the entire contact patch of the tire.

Just curious how did you come up with that ? 37-38 psi equals full contact patch ?

Wearing to the tip of the triangles on the side walls at those pressures.
