What's the lowest tire pressure you can go with 215/45R17 tires!

Depends how much more gas you want your car to guzzle.
Check on the sidewalls for pressure rating.

Don't listen to these armchair experts, especially the one who thinks steel belts are found in the sidewalls of car tyres(they're not).
The pressures are set according to the size of the tyre and the volume of air required to carry the weight on that corner, ie: a fwd car needs more pressure in the front these and a fully loaded s/w needs more pressure all round,especially at the rear.
Use the recommended settings, if you can't find them the rule of thumb is 30psi all round.

My car with factory 215/55R17s recommends 200kpa (~29psi) all round.
I've found I get uneven wear leaving them that low though, 32-34 seems to work much better

yes as above - TYRE pressures in mid 30s is good

Tyre it is. I saw a sticker saying Drury Tires on a car the other day. I thought to myself, does it!

Are you filling with the tyres hot or cold! If hot (like most people) your 32-34 is probably the factory recommended 29 anyway. Even things like whether you did your testing in summer/winter hot day or cold day can have an affect as can where the car comes from (The manual can be written with a hot/cold climate in mind). Sorry if I am telling you how to suck eggs.

I've stopped now, but it was interesting to see that most people carried on and didn't even notice :)

my rule of thumb is 4psi COLD from the max pressure

Cold, the servo is only just down the road.
On a related note the gauges at service stations are all over the place. best to bring your own.

14.8 psi. they will look flat but that is about it.

I'm presuming that's absolute, not gauge.

anywhere between 15 and 40

if you run any less than 34 psi in a tyre of that size it will wear faster if not destroy itself from inside out.
