Default air pressure for RS3

almost 1,000 miles with RS3.
mine are square 245/40/17.
cambers are a touche less than 2 degr all around.

so far i was with 38-39 pressure for the canyon rides and ~41 for the auto-x.

now i see that shoulder wear is nowhere near the triangles.

shall i reduce the tire pressure?

Your best bet is to keep lowing pressure until you see the sidewall indicators touching the should wear line.

thx again for the input.

i'm wondering why you use lower pressure for the auto-x and higher for the road course?
at auto-x the runs are short so the tire doesn;t heat as much and pressure don't get to the desired level...
what's the logic that works here?

Yeah definitely need more. Was previously at -2.8f/3.1 rear and the fronts were getting more outside wear than in. Rears were kind of close to even. Could have had just a little more.
