Update on differential tire pressure thread.

As stated on the other thread, I checked the air pressure on both sides of the rig this morning, and confusion has been re-introduced. The rig had sat in 30 degree temperatures overnight so I know that both sides were the same temperature. All four tires registered 98 psi!! Evidently, the entry-side tires were indeed low since I had added 10 psi to that side. I cannot believe that there is any kind of a leak where both tires would leak the exact same amount of air out each tire. I will check the pressures again in a couple of weeks just to make sure however. Definitely odd??

Bingo,
The two tires that were low may have been warmer when you put air in them before. Just a guess of course.

I had my tire pressure monitor throw an alarm one day right after parking in a truck stop. Both tires on driver's side were indicating a leak. My TPM will throw an alarm if it senses pressure reduction rate too high as well as the absolute pressure too low and it was telling me that both tires were leaking (but still over 100 lbs). Turns out I parked (one side) in a big puddle.

By the time we finished lunch everything was back to normal and off we went. It's surprising how much pressure can change from little things. I can easily get 10 lbs difference driving down the road because of the sun.

Tire pressure changes with additional heat and cold. I have a chart that basically says for every five degrees change (from a base of 65 degrees) that the air pressure changes by approx 1 1/2 pds per every five degrees of temp change. My tires say 80 lbs so at 65 deg my air pressure would be 80. At 32 deg I would air to 74 lbs. At 90 degrees I would air to 95 lbs. Go to this site for the chart: http://www.irv2.com/forums/f84/unive...art-71922.html

Pug,
Good info! I had never seen this and it makes sense.
Admins, I recommend this chart be made available as a sticky.

All that change in temp info is fine, but the bottom line is you fill the tire to the correct pressure for where you are now and what the temp is now. Tomorrow you get up and do the same thing...if the temp (or altitude) have changed and requires a TP change then do it.

Different weights on side to side? heavier on entry? More weight, more pressure... heck I don't know, didn't sleep at that motel last night..
