Proper Inflation Nitto 555's tollroad 80 MPH commutes
 

What would you say would be the proper tire inflation for someone who drives 60 miles round trip each day to work on Nitto 555's.
Half on a tollrad the other half back roads, with only 1 bottle neck the entire way.
Backroads S turns and tight curves, Tollroad typical straights and high speed cloverleaf turns.
Houston weather:
30 miles @ 80mph average in rain or dry, half the year hot weather, other year cold to moderate, NO SNOW.
30 miles @ 45mph average in rain or dry, half the year hot weather, other year cold to moderate, NO SNOW.
Thanks!

I usually run 32 all the way around, and my driving is pretty mixed.
