Tire Pressure Monitor

Just curious if digital tire pressure monitor systems like in motor vehicles has been/could be adapted for a bicycle tire? Something that would maybe beep if say, tire pressure falls below a certain psi would be great. Or even better, a way of sending a number to a garmin or similiar readout. Having a way of detecting slow leaks/low pressure while riding would be nice IMO.

Thoughts?

Wow thanks, that's exactly what I was envisioning. Very cool that he hacked the edge 800 to display pressure numbers via ANT+! $180 is a bit steep, but I would probably back it had I not just dropped a ton of $$$ on a new Garmin.

There's also this hub that includes a pump to get the tire up to a preset pressure while you ride:

In general the only reason cars need monitoring systems is that car drivers are, in general, completely clueless and not in touch with their vehicles. Cyclists are very much in touch with their vehicles and it takes almost no effort to know that your pressure is getting low - in fact you almost have to try to ignore it. It sounds to me like someone's just looking for a gadget.

My current SUV has pressure monitors so I don't check tire pressure anymore. With my bikes, I air them up with a floor pump every ride or at least every other ride. I crashed in a descent a year ago because I had gotten a slow leak in my front tire 60 miles into a century. The tire deflated just enough to cause the front to wash around going around a sharp turn. A tire monitor might have prevented that. If they were simple, lightweight, and reasonably priced, I'd probably run them.

I have seen valve caps rated for a certain PSI(35 or 60, iirc) that would give a quick visual indication(green/yellow/red depending on the pressure in a tire). Can't remember where though, and not really up to searching for them at the moment.

OP, this is all you need to do.

This is exactly what made me think about having a tire pressure monitor. I was recently looking for a new helmet and the reviews on alot of them went something like "This helmet probably saved my life, I had taken a sharp turn not knowing i had developed a small leak and..."

I give my tires a squeeze test before every ride and top off with air every other ride or so. These are slick tires on a MTB and I find myself constantly gazing down while riding, trying to visually inspect the tires if the bike feels sluggish at all. What I'm saying is it's a bit difficult to realize pressures are low while riding until they're really really low.

The Monitor is under your Hat. and your legs , the effort goes Up when the tire PSI goes down..

pay attention..

On tour with a Load I could tell I needed to top the tires Up, just pedalling

I think Battle field Hummers had a way to inflate the tires , while moving
so the pressure can come down for soft ground..

Those have been on the market for quite a while. There are some catches. They're designed for tires that take a large volume of air (automotive tires) and actually require that the tires are toped off more frequently because they do leak a bit of air. Also automobiles generally run lower pressures and still its recommended to check them every week or every day if driving on the highway. A high pressure low volume bicycle tire? You might not finish the ride!
