Whoa Gizmodo just turned the link I pasted into that ad. Holy shit. So that’s where the Kinja engineering resources go.
Anyway, I was at a track this last weekend with it 32 degrees out and I’ve been there when it’s 116 too. I don’t obsessively check my tire pressure. I’m actually a bit lazy about it as race brake pads blacken everything and I guess I’m delicate or some shit.
Anyway real time four wheel info seems like it might be really handy. I just have doubts about the product. Anyone have any real world experience with these things? How janky is this stuff in real life?

No experience with that product but I do know that a lot of people use those laser thermometers to dial in tire pressures. After a lap, they’ll measure the temp of the center of the tread, measure tread temp close to sidewall.
If it’s hotter in the center, too much pressure. Hotter closer to the sidewall, pressure too low. Ideally you want the temp the same across the entire surface.
Gotta be quick with the steel, earn your keep.

If you’re serious about tire management, skip pressures and go to a temperature probe.
For street tires at an HPDE, check your pressures before and after your session and adjust accordingly.
If your tires aren’t feeling weird or wearing oddly, don’t get too obsessive about pressures or temperatures.

I have used TPMS systems for several years now on Tarmac Rally Cars, I have found that having something monitoring pressures to be an ideal tool to have in the car. On a few occasions my driver (I’m the Navigator/co-driver) has called out asking if the tyres are ok, in one case we had a bit of understear going through a corner and he thought we might have a tyre going down. A quick glance up, checked the pressures and then let him know the good or the bad. Most of these systems allow you to set a minimum pressure warning, so if you get a slow leak a very loud audible warning can be heard, even with a helmet on. Most of these systems will also measure temps, so you can note down both pressures and temps before and after your run and then make a more educated assessment of what may need to be adjusted.

There’s no need for real-time tire pressure monitors. Drive your in-lap as you do any other lap and have a helper check and record them in the pit lane before you go back to your paddock spot.

That’s actually what I do and exactly why I do it. I guess I didn’t address the actual problem I’ve had this last weekend. It ran from 30-57 degrees and back over two days. And I’m not a lazy man but the pressure difference from ambient temperature to hot requires a bit of math, guessing, and luck. Or I can look at my dash.
Once you know the PSI to keep them in flat contact you need to keep that PSI and my climate has been changing too fast to keep up with it that reactively.

I have a known very slight leak in the passenger front that I’ve worried would rapidly worsen, which it hasn’t, but it gives me one more thing to think about when I’ve already got enough.
