CHECK YOUR TIRE PRESSURE!

You wanna know why the Northeast came in at the lowest for underinflated tires ? The crazy temps we have to deal with ! 4 seasons. 100 degrees to -10 degrees. That TPMS dash light gets some workout up here. Every single OC, TPMS lght or not, the tires are NEVER at their correct cold P.S.I. No matter what the season. If I do an OC in the summer, the pressure is up a few pounds, each wheel....In the winter, their down 15 pounds. In the fall or spring, maybe catch a break. It's never just an OC !!!!! The ball and chain is funny...." You still doin that stupid oil change ? " I just say...GO AWAY..... Get back upstairs from the garage and tell her " You want 15 min oil changes ?? Go to the Quickie Lube !!! " :)

That’s why I check my tire pressures about every two weeks. The temperature range here in Southern Ontario is quite different from month to month as well.
 
This is going to bug me until I check them. Door sticker says 35psi all around. Car is kept in a garage which is not climate controlled. In this part of Texas, that means it's either hot or hotter than heck.

I recently had a snow tire blow , up on the loft in my shed. It does get hot up there and the pressure must have rose significantly. There could have also been some sort of defect too. Better there than on my truck.
 
Man ! You dodged a bullet on that one ! I had a tire blow @ 70 mph. Thankfully, rear tire. But, what a mess it made of the wheel well and surrounding paint. Scary. My fault though. It was 2 yrs beyond it's lifespan, ( I dump all tires at 5-6 years ). I'll never make that mistake again. It was dry rotted :(
 
I just did it yesterday morning. With the cooler temps, I had to add four pounds to each tire.

I check it weekly, at least.

The most dangerous thing to people like us is a digital gauge that reads to the tenth of a PSI.
You'll be chasing your tail trying to get it perfect. Add a bit of air, it's 0.2 psi over, take out a bit, it's 0.1 psi under, add a bit, now it's 0.3 psi over....

Hehe, that was me today checking the Civic’s pressures 😝 Yesterday I added a few PSI of nitrogen at Costco since it is getting colder out, and today I double checked the tires with my digital gauge. Two tires were at 36.3, one was 36.2 and one was 36.1. I was so tempted to set them all to 36.1 but I left them alone 🤣

There is always something to be learned if one is open to learning and pays attention to things. Every time I think I know too much about cars, I end up getting put in my place. Either by a stupid mistake when not paying proper attention or by someone else looking to teach.

A while back , I checked the wife's tire pressures at 0530am one cool morning before she left to drive her usual 16 mi round trip to work. I always like to put about 33/34psi in them. We all know they call for 32psi but a little bit more is ok.
So, since she is always managing to catch nails , screws and all kinds of debris I check them often. That particular day I decided to check again once she got home, I freaked at first when I saw they all have near 38psi in them. Let some out and could not get over it. Finally went to the wise old techno man - the internet and did some reading.
According to the internet and my actual experience I was the reason. It appears that they recommend NOT checking and adding to them in cool weather. What happened is that morning it was exceptionally cooler for us in this area. According to the auto / tire web site they actually spell out what can happen if one adds press when it is cooler than usual. The heat of the day combined with the wife's drive home at high speeds in really very hot temps caused them to increase in pressure by a few pounds. I never would have believe it can do that unless I had seen it for myself. Still 35-38 psi is not really dangerous but is not recommended. So that evening I decided to let some out and set back to the 32 psi that the manufacturers mostly recommend for non towing or hauling.
 
The HondaLink app will show tire pressure may be down in one tire, but later show a different tire is "low", usually by a pound. Checking with a digital pressure gauge, it may or may not be down. Also, I use a Milwaukee 18v inflator, which is pretty accurate at setting the correct tire pressure. It always verifies its initial inflation, and will either pump a little more or let out some air had it slightly overshot. It's pretty close to the stand-alone, digital gauge. The car is kept in the garage, so it's not due to the sun hitting one and not the others.

When my wife was recently on her trip to Wisconsin and Canada, I watched the tire pressures from home using HondaLink. The ambient air temperature stayed fairly warm, so the tires never lost enough to call her and tell ask her to get them checked, or use the gauge in the glove box.
 
On the two I drive - the dash readings are amazingly close …
I have her Tahoe formatted to stay on open display+OnStar …

Ah ...Mmmmm.... I don't know how to tell you this, but if you have a 3 to 5 psi pressure buildup, that's to be expected for a passenger car tire. Besides, 38 psi is nowhere near the burst pressure of a tire. Burst pressure for a passenger car tire is well over 100 psi, so I don't understand the freakout.

I am lowering pressure on track to 26psi as on track it goes well over 45, and sometimes during hot, summer days, people leave early. That leaves track just for myself or 1-2 other crazy people who like hot asphalt at 103f ambient temperature while heat is at full blast to keep coolant as cool as possible.
So, doing track for 1 1/2hrs bumps pressure well over 50psi. That is time when you can take a dollar bill and glue it on the tire.

32 is under inflated. All tyres in all our vehicles are 36-40 cold.
 
38 pounds in late November should equal about 35 cold in January. I fixate on switching between my air pressure dash reading (which is accurate) and my MPG averages (which are sort of accurate compared to Fuelio computations which I have for my last three cars).
 
I check each Saturday morning and don't fluctuate to some imaginary ambient tempearature requirement. The placard says 33/36 or 32/34 so they get 33/36 or 32/34 all twelve months of the year.
