Two simple questions that came up when mounting tires at home

Hi Clare,
Thanks for the advice that the high-pressure valve "may" leak.
To be clear, certainly I fully _understood_ that if it was a high pressure
tire (like a truck tire), that higher-pressure tire with thicker rims would
_require_ the high-pressure valve, which handles both higher pressure and
thicker rims.
.... but ... (see next section) ...
The "high pressure" valve is likely to leak in a standardthickness
rim
Since both would fit, the question was what the practical difference would
be in a passenger rim with passenger-tire pressures, which clearly the
lower-pressure valve and the higher pressure valve would "fit" ... (where
you answered that question by saying it "might leak" if the high pressure
"truck" valve was used in a low-pressure passenger tire situation simply
because the rim thickness is thinner than the max.
The mere fact the rim thickness is thinner than the max, in and of itself,
doesn't negate either tire valves, where I defer to your experience since
I've used both in the past on passenger car steel & alloy rims and haven't
had a leak at the valve yet.
Did you even LOOK at what you posted???????? READ IT AGAIN and you
won't need to ask STUPID questions!
Clare,
Of course I read and _completely_ understood what the package said.
o The package gave a MAXIMUM rim thickness & a MAXIMUM pressure.
o The package said nothing about a MINIMUM thickness & MINIMUM pressure.
That's why I asked the question, since clearly all the valves sold in that
O'Rielly's had maximums well above what this car rim & tire specify.
Buy the CORRECT parts.
They _all_ appear to be the "correct" parts, in terms of meeting the spec
printed on the package, which is _only_ a maximum spec.
The minimum pressure & rim thickness spec isn't printed on the package.
The tire valve I _wanted_ didn't exist in the store, which was:
o 1-1/2" long brass valve of 0.453" diameter & at least 60psi cold pressure
fitting a rim of no more than 0.156" (3.96mm) thickness...
Which is what I _usually_ buy.
I had to do these tires with what the store had on hand, which is why I
bought both types, but where I put in the brass ones because I happen to
like long bolt-in brass valves over rubber valves - for no real reason
though - they just "seem" stronger.
Do you find, in your experience, that, all else being equal, that the brass
bolt-in valves hold up any better or worse than do the rubber press-fit
valves?
