Indeflate pressure off balance

[graff!t!]

Thoughts, please, on an Indeflate I bought a few months back...

The Indeflate won't seemingly equalize pressure when airing up or down (between two tires).

I repeatably inflate/deflate with a +/- 5 PSI difference on each side and when left to sit on a flat surface pressure doesn't seem to equalize either.

I've disassembled the hoses as far as I can and found no obstructions. Bad Gauge, bad reviews, or something I'm not thinking of?

There may be a difference if one side is in the sun and the other in the shade.

Makes sense but I've tested this a number of times in a garage... flat and in the shade.

OK, weird... Sanity check: If you swap hoses does the same tire always read high or does it follow the hose? Might help narrow it down.

I don't recall if I tried that, I'll double-check...

How are you measuring the pressure? Same accurate tire guage or vehicle TPS?

InDeflate Guage, but also comparing to the TPMS and an analog gauge. TPMS and analog are always the same.

The indeflate is pretty basic; essentially a t-fitting with a hose running to two tires.

The only way the two tires wouldn't reach equilibrium is if there is a restriction (or leak) to one of the two that allows a differential pressure to form in one tire and there is insufficient time for equalization to occur.

One of the hoses then or a chuck to the valve stem? Would that make sense? The tire itself isn't leaking, I can confirm that.

LOL, somewhere there is an award for this answer, if I find it its yours, short succinct and right on!

Here is my approach. Noonday sun, fil each tire individually and aim for +/- .5 psi. Drive a few days and then check psi and adjust to + or - equally if needed.
