It

type of tire. I'd buy one (if it didn't cost an arm and a leg).

What do you think?

I think it would be difficult to calibrate and have a cost considerably
higher than a $2.95 Slime pencil type tire gauge. I picked the Slime
brand
because a review in a motorcycle magazine, where people tend to be less
casual about tire pressures, found it as good as any and better than
most,
including the upscale digital models.






The industry is one step ahead of that.

A friend of mine bought a /used/ car and it has built-in tire pressure
sensors. She got a warning when one of the tires was low.

Since the car was used, that means the technology must have been around
for a while now.

It's a federal requirement goin back a number of years. I'm not at all
impressed with whats offered OEM but after market sensons can be reliable
but you get what you pay for.
