Tire pressure readings using a TPMS

[Skipg]

When using a TPMS how much increase in tire pressure is expected after driving for awhile. Also should the increase in pressure be the same for all tires.Cold pressure reading for all tires is equal. Thanks

The next question will be how much should I DECREASE the cold pressure to make up for the increased pressure when on the road.
The answer is 0 psi.

PSI VS. Temp

You may find these interesting reads.

I make sure that the pressure is where it should be when I start out each day. If the alarm does not sound due to temperature being to high, too fast of a change in pressure, or low pressure I don't mess with it. Sometimes too much information will make one a little paranoid.

Lots of options, heat, sun, cold, weight and more. There is no set number.

Yup, same here. One day last month I looked at the Pressure Pro and 6 of the 8 fiver (2 axle dually) tires were exactly the same! First thought was something must be wrong, they usually vary a couple of pounds.

They do increase different amounts depending on several factors.
Sunny side of RV
Road roughness
Inside or outside dual
Crown of the road.

The variances bothered me some on the first couple outings.
Then I got used to it and jsut remember now that it's main purpose is to alert me if something is going wrong.

Same with me. 10-15 lbs.
