I am in Chicago and the temperature has dropped to low single digits.

My RC F tire inflation has dropped to 26 -27 lbs. due to the extreme cold, after it has been outside for a while. I am wondering if any of you have experienced this and what you are doing about it?

After driving for a while the tires heat up and the pressure goes up, returning to normal range.

 

I'm from Chicago too. I just filled the tires up with air until it gets to 36 PSI.
I only did this because my pressure didn't go up after driving. I'd think you're fine just leaving it alone lol.

 

I'm way down in the South, but IF they go back up After you drive it then what's your Issue?

 

I guess I am worried about not having as much control during the time that the tires are warming up. I drove last night on 29 lbs. for while, however and the car handled OK on the interstate. And I think the tires might be more vulnerable to punctures when the inflation is low.

 

I think factory psi is 36-38 so I would at 5psi due to extreme temps, so bump all tire pressures to 42psi

 

Factory in mine says 36, i usually run around 34 just to get a lil' better ride. I'd be a lil' worried to put 42 in my tires Especially if they usually go back to normal pressure after you drive it for a bit. Having over inflated tires in the cold/winter up north i'd think that wouldn't be a Good thing But, like i said i'm in the South so i'm not the Best person to give you advice.

 

Keep it at 36psi from a cold start. A little higher psi protects the wheels from bending but the tires will take the hit from potholes

 

Always inflate tires when cold. And yes, they should be at 36. You lose 1 psi for every 10ºF, so once you inflate your tires to 36 in the cold, they should only lose the typical 1 psi per month (normal seep). And once it starts warming up, you might have to actually remove some air. I check mine often (especially on bikes), but once a month should be enough.

 

This is approximately 10 pounds too low and not desirable. Check them when they are cold and bring them up. When the weather warms in the spring, adjust as required.

 

Thanks for the advice everyone, you guys are the best!

 

Driving on Summer Tires in the extreme cold is a Very Bad Idea:
