are they manufacturer specs for tire pressure the same for both auto and 5speeds? I know that the auto tranny weighs alot more up front so do they compensate it with higher tire pressures? I been playing with pressures lately on my 16x7.5 225/50/16 and most of the suggestions I read on the search feel too low so right now I have it set to 37/33.

 

I always set mine 35/33 cold. When it has rolled for 2 miles or more, I always set up 36/34.

Pretty stiff for 235/45/17, but that's what I prefer. For comfort, I would set it at 34/32 cold.

Oh, mine is auto BTW.

 

I have mine at 33/32. Rides fine. I like it.
