Tire Pressure Monitors in 2011 Equinox

I don't know that the pressure sensors in the tires are any more or less accurate than the average tire gauge an owner has.

Just my opinion, I'd go with the reading that's the lowest.

A couple of extra pounds won't hurt and my help with tire life, fuel mileage and handling.

These are highly regarded gauges.

My sensors read the same way. However, they haven't always been inaccurate. I have 11,000 miles and I've noticed it become inaccurate after the last few thousand miles. There was no tire rotation or anything done in this time, so I know it's not that.

I actually have that first tire gauge on that site above.

My TPM always shows a few pounds less than my hand held Accu Gage

This is why I was wondering if when you "reset" the tire pressure sensors, like when you rotate the tires, if it kind of recalibrates the sensors, or if there is even a way TO recalibrate them. Seems pointless if they consistently read inaccurately.

I don't care if they are super accurate I think the main purpose is to let you know if one tire is much lower then the rest of them and which one it is.

I agree 100%. However - if mine have only become inaccurate in the last few thousand miles, my concern is if they progressively get MORE inaccurate. Know what I mean? It would be annoying to have properly inflated tires and hear that chime go off every time I start the car, telling me my tire is under inflated.

I run my tires at 40 lbs. normally. I long trip coming up and I'm bumping them to 43-45 lbs.

Wow - doesn't sound safe to me, but what do I know ?

Sounds to me that it would put alot of excessive wear especially to the center tread...not counting unsafe.
Over-inflation not good.

Don't know about he 'un-safe' part, but I have a couple of acquaintances that run at the MAX pressure on the side of their tires.
That's more than what I run.

No problems in several years. Two cars and a 4X4 Dodge Ram.

I have rarely seen tires worn out in the center of the thread.

I usually run mine at 38-40 With no issues, and a good "dependable" gauge will make the difference when airing them up, just for the sake of discussion does anyone know if they are filled with Nitrogen from the factory or just "air'......inquiring minds wish to know.... ;D

I doubt if they are using 100% Nitrogen, because if they did, they certainly would be saying it in their advertisements, right ?
