The Genesis doesn't display the actual pressure, so I had to manually check the tire's actual pressure with a gauge. Thankfully, it was only a little low compared to the other tires, and I didn't see any screws or punctures during a visual inspection. So maybe the cold morning temperature dropped the tire's pressure enough to trip the TPMS. I filled the tire back to spec at a nearby gas station and have been keeping an eye on it. So far, no more warnings. Brent Romans, Senior Automotive Editor @ 22,645 miles
The more TPMS warnings in get in various cars, the more I'm thankful that this feature is now standard in every new car. I got a low-pressure warning in our Hyundai Genesis a few mornings ago for the left-rear tire. My wife had taken the Genesis shopping the day before; did she drive over some road debris?

Here in Oregon, Dad's Toyota Tacoma threw a TPMS warning while he was in town. He drove straight to his buddy's tire store. One tire was about 7 psi low and they found a nail in it. Problem solved with no roadside flat tire drama.

I've had similar experiences with TMPS. Everytime it warned me, there ended up being a nail or some sort of issue that was easily solved before getting stranded or needing to change a tire. I love it. Sure some people say "you should check your tire pressure regularly" but that doesn't mean you won't pick up a nail two minutes AFTER you checked the pressure. TMPS is about warning a driver in realtime and allowing them to fix it before things get serious.

Here's a question how does TPMS handle diffent sized tires like large truck tires or even mudders?

"Hyundai Genesis: TPMS Makes Me Thankful" "The Genesis doesn't display the actual pressure, so I had to manually check the tire's actual pressure with a gauge. "
Wow, The Genesis does not display tire pressure?!? (How much was this car again?) This is akin to the idiot lights of yore, and how they were maddeningly frustrating as they did not help you figure out what your true problem is. This creates extra steps that don't exactly help a driver out. My G8 GT shows tire pressure and lets me know if its a big problem or a little problem right away.
If TPMS did not show the actual pressure I would be anything but thankful!

I wonder how much weight the TPMS adds to the vehicle and how much of that is unsprung in the tire.

Shame on Hyundai, and several other auto manufacturers who don't display the actual pressure. The engineers should be smacked across the head for this. The computer knows the actual pressure of each tire, so why not display it??
Kudos to GM for this: most of their vehicles display the actual tire pressure at each wheel.

Why? Don't you carry a little portable compressor in your trunk? They are usually $15-$25 at any parts store and work off your 12V battery.
And P.S. I agree with flyusmc's comment -- my Honda minivan can do it, so can a luxury car.
