PSI for Pilot Super Sports, 18"

So what's the proper PSI? I did do a google search by the way, but got a 1000 different answers. Is it really 31 for front and back? Seems low.

Mine came stock with 18s and the door sticker states PSI as F32/R32. I would take a pic but currently traveling for work. I think the manual said 31 all around. At least that is for the under 100mph category. I run 32.

Thank you very much, sir. I really appreciate it. I did manage to check out the manual and saw that it says 31.

For the street I was running 2.2 bar (32 psi) cold - thats what the sticker reads.
At the track I was targetting ca. 2.4 bar (35 psi) hot all around.

On my 18s they had notably worse ride quality, steering input, and tramlined to a much greater degree at 31-32 PSI than at 34-35 PSI. The difference was too notable and too consistent to be placebo effect. I could drive down certain daily-driven roads in a straight line and feel the tires act a bit squirrelly and then check and the PSIs would be 31 (i.e. loss due to cold weather).

Bear in mind I drove 20k miles on my stock PSS, so some of my comments are derived from how they acted AFTER 5-10k miles were put on them in the first place.

Thanks. I will give that a try.

I've futzed around a little bit with tire pressures on my 513Ms, and I've decided that 32 psi cold all around (door sticker recommendation) is just about right.
