WHEN - to check air pressure??

[R***A**N**G**E***R]

Ok I know that if it is summer time and it's 80 degrees out side and I just drove 20 miles my tires are going to be HOT and air EXPANDS when hot so I know that if I take a reading of my pressure during the above scenario I am absolutely going to get a DIFFERENT reading then parking my truck in the shade and not driving it for a couple hours SOOOO lets park the truck in the shade and not drive for two hours THEN take my pressure and at that moment ajust to my specs which is 35 psi.

So now I drive down the road in the heat and take my pressure and now it is reading like 40 something,lol, so to make a long story short should I take my tire pressure during winter while it's like 45 55 degrees out or when it's like 20 degrees out?

The other day I checked the pressure with my DIGITAL gauge and it was about 50 degrees out and my tires were not in the sun and I had not driven for about 2 hours and I put EXACTLY 35psi in each tire.

Today ( at this moment ) it is about 15 degrees and I just checked the pressure in all four tires and they are reading like 30- 31 psi SOOOOOO if the temp out side is going to be below freezing for several weeks shouldn't I got pump up the tires back to 35 psi knowing they kinda sorta technically ALREADY have 35 psi in them assuming it was just a bit warmer out side

Are you following me? do I ride around for a month in cold weather at 30 psi and be under inflated knowing that if it just warmed up my tires would be back at 35 anyways.

When it's cold out, it doesn't hurt to add more air - as long as you don't forget to take it back out. You're thinking too hard about it.

adjust air pressure before driving. if its 30 psi at 30 degrees F. before you drive then you need to add air

if its 40psi before you drive at 70 degrees F. you need to remove air

the outside air temperature does change the tire pressure but you just have to keep adjusting it before you drive no matter what temperature it is outside

i usually do it when the tires are cold, when theres a drastic change in outside temp(like when it starts getting cold all of a sudden, or hot all of a sudden), i try to check em every time i fill up, about once a week

i check mine every morning. i just walk up and kick'em, if they got air they're good.



naw, i check mine once a month, 32 psi rear 35 fronts. i do check them every morning though. just outta habit lol

You are suppose to check tire air pressure when its the coldest outside. I find its easier to calculate and adjust them according to what ever the temp is when I do fill them.

Summer:
50*F = 32PSI
60*F = 33PSI
70*F = 34PSI
80*F = 35PSI
90*F = 36PSI
100*F = 37PSI

Winter:
20*F = 32 PSI
30*F = 33PSI
40*F = 34PSI
50*F = 35PSI
60*F = 36PSI

I change the pressure when the temperatures start to get below 50*F for winter or above 50*F for summer. As is now, I'm running with the winter pressure adjustment.

Well on my ranger it will tell me when to add air if the tires need it. But in my b2 I check every other week or so

Every fillup I check the air pressure. Keep a close look at on any unusal wear pattern on your tires as well. It's just a rule of thumb. At the same time..... check the oil, water (overflow bottle) wiper filler and look at the battery for any corrosion on the battery terminals. Check your parking area for any oil leaks that might have started. Your truck will last longer and take care of you the more you take care of it.
