So im sure many have seen the new commercial im thinking it was the new Nissan anyway when your tire psi gets low you will get a warning light on your dashboard. then when you decide to fill up with air , you will not need a tire pressure gauge, cause when you reach 32 psi your horn will honk. thats just cool. im gonna wait til a off brand comes out where your able to install this gadget on any car. i will put this on my concorde. im thinking all four tire need to be taken off and some type of sensor needs to be added to the rim inside the tire , and then maybe some type of remote relays? cant find the original commerial , but found this to give you guys a idea about this new thing that peaked my intrest. curious about cost , i dont see it costing much more than $150?

 

This system is been available for years , my Chrysler 300 2004 and town and country come with it, this shows on the top panel display, but not in my Pt cruiser GT so i purchase this set and install it almost 2 years ago still working
