What tire pressure should my tires have??
I just got a tire guage, and when I checked my tires, they were at 31.5 psi. The max pressure for my Michelin Pilots states 44 psi. Should I increase the pressure to that level? I don't want them under inflated. Thanks.

31.5 psi is a bit under-inflated, yes. Try 36 psi, then go up or down according to your preference.
Some people here recommend 38-39 but I really think that's too high and unneccesary.

It depends on wheel/tire size. With 225/45/17 you might want 39 or 40, while with 225/40/18 42 or..
44 is more appropriate. The smaller the internal volume of the tire, the more pressure. That's why that donut spare needs to be inflated to 60 psi. 225/45/17 tires state a max pressure of about 44 or 45, while my 225/40/18s have a max pressure of 51 psi. I would never recommend inflating to the max psi, by the way, necause there is a variace due to temperature.

Thanks...so should I be at 36 or so? My tire size is 16...standard sport tires
I assume that pic. is from the notice in the door. That maybe why the dealer inflated to the levels they are now. Should I increase?
