depends on your desires.
road conditions here are sometimes not the best, so i inflate a bit more.
In addition the sidewall composition plays a part, so depending on how
much deflection (which should be less on the 18's) balanced with a
reduction in footprint (too much pressure will reduce your contact patch
signifigantly) you shoud pick a place.
fwiw, i up'd about 2psi from stock and run 4psi lower in the rear as
compared to the front, assuming 1-2 occupants. I up the rear a bit when i
do a run to the airport to pick up family/friends/luggage.
IIRC, the washington roads weren't too bad, but not the best either. That
combined with any potential alaskan run you might want to do - i'd suggest
a few PSI over stock to keep the rims round :)
btw, is it possible to drive the S4 all the way to the artic circle on
paved roads? maybe i'll try it.
