The Ford warranty covers the tires. The amount covered depends on the
mileage. I am past the 12,000 mile mark (100% covered till then), but in
theory Ford will cover 60% of the cost of the tires, if the problem is the
tires (at least till I hit 24,000). And the tires may have a manufacturer's
warranty as well. But, I suppose I'll need a little more history before I
try to get Ford to do anything. I'll monitor the tires for a couple of weeks
and if they still seem to be losing pressure at an unusal rate, I'll visit
the dealer. I can't imagine this will be an easy sell, but you never know.

It's /very/ unlikely to be the tires that are leaking unless there's a
puncture. And it's even less likely to be a puncture if all four wheels are
exhibiting pressure-loss at the same time. Unless there's some kind of
obscure manufacturing-defect, of course.

Your most likely culprits are the wheels (porous alloy; poor sealing at
rims), or the valve stems (core; at hole where stem goes into wheel).

This is why you get the warranty that came with the car...

If the tires had this problem from new, I'd agree porous wheels could be the
problem, but I doubt four wheels developed similar poroisty after 10,000
miles of use. I just don't picture anything I've done with or to the car
could increase the porousity of aluminum wheels (Ford OEM).

The valve stems are a possibility. Ford uses TPM sensors that incorporate
replaceable rubber valve stems. The same sort of valve stems were used on
two other Fords I've owned and never gave a problem. It is certainly
possible that the stems are at fault, but it just seems unlikely that all
four would fail at about the same time and lead to similar leage rates. I
suppose the stress of the trip to Florida could have affect the stems but I
think it is more likely to be the tires.

I am focusing on the tires becasue I wonder if the stress of the trip to
Florida (hot temperatures, bumpy / lousy I-95 road surface, continuous
driving for 9 hours in each direction, etc.) might have damaged the inner
structure of all the tires (and since I've never had Kumho tires before, I
am suspious of them). I've checked in the Fiesta forum and no one else has
reported a similar problem. Googling leaky Kumho tires get no relevant hits,
etc. I think going back to the dealer is the samrt move, but I want to
monitor the tire pressure for a few days to confirm they are leaking at an
unusal rate. I can't imagine what the dealer will want to do to confirm
slowly leaking tires or wheels or valve stems....... But whatever, if the
problem presists, I'll get the dealer involved.

yup - But I would think that porous alloy or sealing would possibly
give you different rates of leakage, even if it were a problem on all 4
rims. You might lose air, but I would think it would not be even across
all 4. A problem with the valve stems during manufacturing might me a
little more feasible. From something as simple as a batch of stems
where the assembly process (either automated or manual) did not
torque/tighten the metal plunger into the stem correctly (which is
something the poster could easily check if he has a valve stem tool) to
a manufacturing defect in the rubber itself (which is what was wrong
with the batch that BJ's got in my previous posting) where it was
gradually dry rotting on the inside of the rim, allowing the rate of air
loss to gradually increase over time.)

But I agree - Just take it in...That's why he has the
warranty...Shouldn't even have to think twice on a car this new.

Who knows, they may have had the problem on numerous other vehicles
and know EXACTLY what the problem is, and fall all over themselves
fixing it for you. Then again, you MAY be living in the "real world"
- where even if they HAD seen dozens of them, they'd deny it.

I had 4 valve stems (without TPM) fail within weeks of each other -
they just cracked and let go - all at about 15 months, give or
take.I've owned dozens of vehicles - and serviced hundreds more, with
"exactly the same valve stems" without ever having one fail (well, the
odd one on customer vehicles over the years - but none on mine) - yet
with the cheap chinese crap currently on the market i DID have ALL 4
fail in a short period of time (first one on a trip to the east coast,
second just after I got home, third in my driveway a week later - and
the forth the same day when I checked it to see if it was shot too -
just wiggled it a wee bit and the air started leaking.

Take the tires and rims off and throw them in the shallow end of the
swimming pool - and watch for a tiny stream of bubbles. Pourous
casings were a not uncommon problem not too many years ago on several
brands and models of tires - the solution was to install a Michelin
Airstop radial tube. (gee, I wonder why THEY were marketed??)

I replaced some Michelins with good level Kumho's, and was
very pleased with them. I did not at all find them to be of
low quality.

Get your soap bubbles out and see if you can find where it is
coming from.

The valves may be the answer.

I have also had tires leak VERY slowly at the bead....so slowly
that the tire companies couldnt find the leak with soap. But,
as the pressure drops, the sealing force decreases greatly and
then the leaks become obvious. In a few cases, I have had to
dismount the tire, sand down the bead area, and paint it. In
a few cases, I have found moisture inside the wheel, and some
corrosion where the wheel disc is welded to the rim.


These may be hard to find, but not impossible.

Consider the other half of my "porous wheels"comment: Poor assembly-line
technique that results in rim leaks.

Unless there's a design or assembly fault.

Can't see that being an issue unless the tires were defective. Modern
tires are extremely tough, and are highly tolerant of very significant
abuse. Tires are old technology: All the bugs were worked out ages ago.

Kumho and Hankook are excellent-quality tires. The Koreans have tires
down pat.

What did Ford change for 2011? new designs? new suppliers? new plant?
new equipment? new process?

VERY good idea. Keep as accurate records as you can. Remember, engineers
will be studying your records, so you must be as precise, as organized,
and as detailed as possible.

If you can go into the dealer with substantial and credible evidence,
you will be able to help them to help you solve your problem.

And, if this is a brand-new problem, your research may even be able to
help cause a TSB to be issued. You'll be famous!

You may even discover...Devil's advocate speaking here...that your
original thesis is incorrect, and that the tires are not actually losing
any air at all...
You never really know, until you have extensive and accurate records to
work from.

It involves water. But wonder not: This is their problem, not yours. If
Ford is the conscientious automaker they wish buyers to think they are,
their engineering staff will have developed numerous techniques to find
defects.

Some automakers are wonderfully anal about detecting and correcting
faults. You'd hope Ford is one of those.

You paid for that warranty as part of the purchase price of your car.
Time to start collecting on what you paid.

theoretically, but manufacturing integrity is just as susceptible to
"economies" as it ever was. thinning/omitting the air liner saves
money, regardless of "old" or "new" technology.

frod is right behind bmw in terms of their relentless pursuit of
production and design objectives and quality control. however, the
targets they so carefully and rigorously meet are not those you would
suppose.

life limitation is, and has for many years, been the hold grail - their
largest r&d spend by a considerable margin. it's cheap and easy to make
reliable stuff. it's cheap and easy to make unreliable stuff. it's
very hard to make cheap stuff that's reliable only for its design
period, then reliably and predictably fail. in terms of engineering
challenge, this is probably the only thing about the industry that's got
any real intellectual horsepower behind it. getting stuff to work?
that's century old news.

Riiiight. If they can find them in the service manager's round file.
What I'd do is just tell the service manager I'm tired of shoving
quarters in the local tire pump every couple weeks.
If he's smart he'll tell his crew to tank the tires. and fix any
leaks.
If he's real smart he'll tell them to fix any found leaks, and also
break them down, clean the rims and put on sealer, and replace the
stems, cleaning and sealing there too.
Then CE will be a happy camper and maybe buy another Ford.
I had this done last year for 2 slow leakers on my Lumina, but they
were about 4 years old. And it cost me $44 at Just Tires.
Went a full year without air loss before I got new tires.
Worth it not having my wife nag me every other day to check her tires,
and use my lousy brad nailer tank to pump them up when needed.
Alloy rims, but I've had the same issue with steel rims.
Just "regular "stems. First thing I'd suspect with new tires is the
new-fangled stems. But that might be all wrong.
I'd fully expect the dealer to set this right on CE's car.
