Hello Tony5 and All, Neat but too big ... It is not so much the price that causes me to hesitate buying .... but rather size and weight.
I do not know how to make it .... yet .... but channeling on the pocket size tire pressure gauges that have a graduated part that extends to indicate pressure ...
Price $2.27
Perhaps this design with the little graduated part that is visible located in a streamlined clear valve extender weighing only a couple of grams.
It could be colored green in the acceptable pressure area to make it quick reading ... and so you would not have to stop to read the tire pressure ..... for on the fly pressure data ..... the little pressure data stick could cover a small hole when in the acceptable pressure range ..... when out of acceptable range the little uncovered hole would whistle .... giving you an audible warning of low tire pressure.
Simple, cheap, effective.
Another solution would be a very light graphene cartridge filled with Nitrogen located inside a self sealing tubeless tire with a pressure sensing valve that released the Nitrogen any time the pressure in the tire fell below a certain level. You do not really need to know the pressure .... you just want the pressure to automatically remain optimum.
Or better yet .... a tire with good Crr elastic properties that did not require inflation and would not flat ..... and throw away pumps, tire gauges, self sealing fluids, patching kits, etc.
Any thoughts?
Cheers, Neal
