Valve stem mounted device like a TPMS sensor, but that keeps your tires full of air

[richar18]

Hey everyone, I would like your opinions - I am a grad student working on an engineering project that looks like it could show a ton of promise as an auto-inflating tire device. It would be small (about 1" x .6" x 1.5", or a little smaller than most TPMS sensors), and could fit on the end of a valve stem like a TPMS sensor. The cost would be under $100 total for all 4 tires, likely including installation at a commercial tire shop. It would pump enough air at typical speeds to keep your tires from going flat if you ran over a nail. It uses no batteries, and only pumps at over about 25 mph.

I am curious as to how well recieved you guys think a product like this would be, and how you feel this would stack up against TPMS's. Would you be interested in this type of technology? It seems like a good idea, but I would like to start getting other people's opinions. Thanks!

I agree, it certainly does sound like a great idea especially at that price.
