Wonder how that works if you get an aftermarket setup that's bigger than normal. Does use the difference between left and right? Can these systems be recalibrated by the user? It's not out of reality for an aftermarket wheel/tire setup to be +1/2" different in diameter.

It looks for deltas, IIRC.  Which is great unless all 4 tires are low (lot of people don't top up pressures when cold weather hits and run on 4 tires that are like 10 psi low).

Yea, how do these newer systems deal with just normal tire pressure decrease from temp? Or are they just assuming they are nitrogen filled?

The indirect systems have worked flawlessly on my current car and my previous car. They caught slow leaks quickly so that I was always able to catch them before they got too bad.

I understand they have limitations but for the benefit of being able to simply and easily swap wheels and tires I am more than happy to make the trade.

What difference would nitrogen make?

And yea the temp drop is a biggie. Speaking of which we just got a cold snap....

Nitrogen gains and loses pressure with temperature just the same as air.
Maybe we need to start off small. I mean, they don't let you fuck the glumpers at Glumpees without a level 4 FuckPass, do they?

However when it gets cold an warms up, nitrogen tires come back up to pressure.  You can set them a few pounds high in the summer and never worry about them for years

no, you can never ignore tires for years.

The pressure comes back up too.  The only thing straight nitrogen does is it has a slightly lower loss rate. If you check your tires every six months or so (which should be done regardless IMO), it makes no difference whatsoever.

I haven't adjusted tire pressure on my JGC in 4 years.  Nitrogen filled tires don't need the top off.  Loss rates are dramatically less.

2.2 PSI/year versus 3.5

Its not dramatic, its marginal. All you're doing is replacing 82% nitrogen with 95%

I've never had for 4 years tires go to 37psi in the summer and 33psi in the winter... and cycle like that for years.

Don't really give a damn about what the internet says.

Well, when it comes down to whether or not to believe my own experience, laws of physics, and Consumer Reports methodical testing, versus your anectdotal observations (which are always detached and objective)- its not a hard choice.

Fuck that, I'm gonna go get nitrogen in my tires and throw my air pump in the garbage. #r0torway

It is especially important to keep tabs on your tire pressure with low-profile tires.

Utilizing my on-board g meter and a few joy rides with passengers, I think I've come to the conclusion that 0.5 - 0.6gs is the threshold of a brown stain moment for most people

That seems low. I'd have guessed .75 at least.

Do the seats clean up easily at least?

I suggest you do, that way when it breaks down you can blame it on the aftermarket tune, not the Alfaness of your Alfa.
