Anyone have any experience with this?

supposted to be a valve cap that auto checks your tire pressure and give warning if it drops 2-3 psi

 

IMO if you gotta look at each tire you might as well use a guage and know the pressure. If you want something more advanced look at Smart-tire monitoring (tirerack) or something similar.

 

well this will allow you are a glance to see if the tire pressure dropped 3psi


taking out a guage takes time

that monitor thing cost too much $$

 

^ if you're lazy and don't mind when your tires vary by 5-10 psi, go for it! but those things are notoriously inaccurate and if you can't tell your tires are low by 5 psi... maybe you should buy a buick?

 

This is better in the wheel/TIRE forum.

 

this thing detects a 2-3 psi loss. i have a car w 19 rims and 30-35 aspect ratio. 2-3 psi is a big difference on a tire like that.

 

So it says. You will be surprised by how good those things work. They will tell you every three days that your tires are low because that is how accurate they are, oh wait, or is it because they leak air themselves

 

hahah well for some tires i notice a 5 deg temp change can equal to 1psi change

 

I uh... had a friend that put them on his Jetta. It seemed to work ok for a few months until it rained and water got stuck under the plastic. Then it stopped working.

It's a POS.

 

oh well... scratch that idea then.. thx for saving me 20 bucks
