tire pressure warnings

My wife has told me that for the last 3 mornings (the overnight temperature has finally dipped down into the high 30's) she has gotten a low tire pressure alarm right after starting the vehicle. After driving a few miles (and tires warming up) the alarm goes away. Under normal operation the tires display around 35 psi

Sooooo.....should I add a pound of pressure (incrementally each morning until the alarm stops) to try and eliminate the low tire pressure at cold temps but hopefully still remain in normal pressure range once the tire warms up?

any ideas?

It happens every time I get a nail in my tire. But it's only low on one tire. If yours are all the same pressure just pump them up a little. I try to keep mine at 35 lbs cold.

35 PSI after the tires have warmed up is perfect. I would not adjust them at all. 35lbs cold is too much air and will negatively affect the life of the tire.

Hi
Read the label on the door and in the handbook this states COLD pressure recommendation at 35 psi and that is what they should be when COLD, if they are lower then recommended threshold the warning light will come on. So yes put some air in.
Regards,
Merlin

I should have noted in my comment above that the size of wheels you have makes a difference here.

Tire pressure

Stock Jeep Patriot 2010 Wheels are 17 " the tires Continental 215- 60 -17.

Referring to Continental web page for my specific tire they say 40 psi for driving around town
35 psi cold for out on the highway.

at 40 psi i do not notice any lack of vehicle comfort
Under inflation will cause the edges of the tire to wear pre maturely during slow speeds..

Don't forget the spare PSI.
I keep mine at 42 Psi because it is difficult to recover from the tire / wheel well

I keep my tires at 35 lb cold and I get rough riding with more than that. I think 40 or 42 lbs is the Maximum and not the recommended tire pressure.
