Been looking at these at the local Discount Auto Parts, they come from the manufacturer set at a certain pressure (32lbs and 36lbs). You screw them onto your tires valve stem and, if the pressure drops below the setting a little red ring becomes visible. There is a green ring that is visible if pressure is above the setting. Well, been looking at them for a couple of weeks but couldn't get around the "cheesy" factor. Finally bought me a set of the "36", I run 36 in the front and 40 in the rear. Installed them and, lo and behold, my rear tire was low (31). Fired up the compressor, filled the tire. I know, it sounds cheesy but they really don't look bad. I suspect most people won't even notice them as they are mostly hidden by the brake rotors. Anyway, I know they ain't chrome and ain't from Harley but they do seem to make it ez to check the tire pressure.

 

ive had them fail and slow leak .

 

thanks big..gonna keep an eye on them

 

got nothing but bad reports on these things, took them off.

 

I wouldn't use them. They'll probably start to leak.

 

A couple of years ago I put them on the wife's car because she could never tell if a tire was low or not.
They ended up cracking and leaking. Tire dude told me it happens with them all the time.

 

had some on my RV trailer. Same thing, they developed a slow leak after a short time. I think you did right by taking them off the bike, a slow leak is a lot more of a safety issue on a bike than anything else.

 

I had them on an old bike. I thought they were so cool until I did a dyno run and the darn thing came apart and the tire went flat. Sure glad I wasn't on the street. By the way I also took the front one off to.

 

Looks like great input to me, I thought about putting them on my cages - not now, thanks.

 

Been using the 38 psi "green band" types for 18 months. No leaks, no problems, and accurate. I find that it's far easier to do a quick 15 second visual check, than un-cap and use an air guage. Therefore I do the quick check almost every time I throw a leg over the bike. I think that's far safer!
