Temperature drop, tire pressure check!

[radroach]

Just a reminder everyone, daylight savings time changeover and also it's cold, your tires have probably dropped 5 psi if you haven't checked over the last couple weeks, so get out the tire inflator and put some air in if you need it!

Should I change the battery in my car also ...... ??

i think its a reminder to swap on those winter tires

@humfrz maybe, my car starts slower than usual when cold, slower than it usually did 3 years ago and still on stock oem Panasonic battery. I've had to do a couple jump starts last year after running my emergency lights.

But for tires, I recommend keeping an eye on your tire presssure temps during autumn. Our southern sunny 90*F weather here is going to start dropping to the 50* soon. I had 5psi drop out of each tire and couldn't figure out what had happened to my handling, @CSG_mike said my struts were worn, but really we just had cold mornings and my tires were low.

YEAH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I damn freasked myself out. Forgot that the weather really impacts these wheels!

Two weeks in a row damn TP light on! I added just 2psi, three days later again low TP! Then finally over filled by 3, and since then, been good!

Its cold? Where? It was almost 80 today in North Ga.
But I'll keep it in mind!

.

I was just going along with fall, lower temps, daylight savings, change smoke detector batteries .........

Truly. I live in south Florida and it doesn't matter how warm it can still be, a temperature drop is a temperature drop. Just a few days ago my tires dipped to 20psi from 30psi

We can get temperature swings of 30 degrees overnight here and I have NEVER had any tires drop more than a pound or two. A 30% drop in pressure from a few degrees is not likely. There had to be something else at play.

"The rule of thumb is for every 10° Fahrenheit change in air temperature, tire pressures will change about 2% (up with higher temperatures and down with lower). This means that light-duty, standard-pressure tires (typically inflated to 30-50 psi) used in applications on cars, vans and light trucks will change by about 1 psi; where heavy-duty, high-pressure tires (typically inflated to 80-100 psi) used in applications on recreational vehicles, busses and trucks will change by about 2 psi." http://www.tirerack.com/winter/tech/....jsp?techid=73

Did you really have a 100 degree temperature change?

I'm sure there were other factors. Humidity, time of day, temperature when the tires were filled, whether or not you've been driving, the placement of the stars. So far they haven't changed in pressure anymore, but the temperature has been steady, so it can't be a leak

You have bad sensors if they are going off with 2psi loss. I believe they are programmed to go off if the tire is under 17 psi.

I had the opposite happen. It warmed up 10 degrees and my tires blew up from over inflation. Sucks!
