On my F150, I would have to go with a longer center bolt. I'm not sure if
the nut assembly would interfere but I don't think so.

Not enough snow/ice here to bother to change the automobiles out and the
4x4 PUs all have all-weather on them, anyway. When it does snow here,
it almost always blows so much that car can't do anything with the
drifting anyway because such low ground clearance so the tires really
make no difference.

Bought the wife a Buick Lucerne w/ the AWD and 20" rims so she'd have
something w/ more traction/clearance on the muddy roads when it does
(rarely last several years of drought) rain enough that the roads are
muddy...it's been useful a couple of times since had it for the purpose.
It's also actually a decent field-errand car for meals during harvest
time and the like as she's so short that getting in/out of and driving
the 4-wheelers is a lot of work and she doesn't like them. The Enclave
handles the sandy fields very well and has enough clearance to not high
center unduly or be a terrible fire hazard w/ the catalytic converter
dragging stubble...

Of course this is something that you cant just learn. But in my older

I'd be willing to put that to a controlled test/demonstration...

With truck tires I could usually pick up a tire that was 10 to 20 pounds low
by thumping. They were 110 psi tires and you were thumping two side by side
so you had an immediate comparison unless both were low.

Down 40 pounds or so almost anyone would pick up the duller sound. As for
exactly 110 psi, I definitely wasn't that good.

The temperatures here tend to hover around 32 for much of the winter. Add in
an inch or two of fresh snow, sometimes every night, and you have a perfect
environment to turn roadways into ice rinks. All weather treads don't do
much, nor is 4WD all that useful when all four are sliding.

The city is very religious about snow removal; God put it there and God will
remove it when He feels like it. The main arteries wear down to pavement
eventually, but the side streets just turns to ice, with nice frozen berms.

Wife's car has these sensors. One went bad and showed tire to be under
inflated when it was inflated to the proper pressure. Dealer charged $100
for a new sensor and $100 to put it in. I would have been tempted to put a
piece of masking tape over the red warning light. I have the same model
car but older without the sensors and I've never been worried about it.

I rented a Toyota that had a screen that showed the pressure of each tire.
Warning light came on but did not say which tire and I had to check them
all with my gauge. Being a rental car, they varied by about 10 psi.

Our masters in DC have mandated this. Can't wait for the mandated backup
camera - more expensive **** to go bad

You were ripped. OEM replacementas rub ~ $50 all over the internet. Many
tire dealerships will do the replacement for free.

Probably close to 10 yr if not longer; not sure whether it's yet in the

Yes, it is mandatory and has been for several years. The other "nice"

Buying a *good* tire pressure gauge with a good chuck on it makes checking pressure less frustrating. Good chuck especially, I want one that will go on and off with minimal pressure loss. My local speed shop just had a sale on "last year's model" Longacre dial/hose type gauges for $20 so I bought a new one and gave my old one to a kid who didn't have one at all.

Which reminds me, I better actually check that the new one works before the returns window runs out

Better yet, I used a Cornwell digital inflator last time I was at my friend's shop with a locking chuck, damn that is a sweet tool. Apparently there's a new Cornwell rep in the area who's aggressively trying to catch all the shops his predecessor missed... sure that one isn't $20 though.

It has but I would not rely on it unless you have an actual pressure readout in real PSI. a "Low Tire" warning just means that the tire has 75% of the door sticker pressure, I'd prefer to know before that point.

Lucky you! The TPMS on my car were calibrated to
-5psi below the maximum pressure on my TIRES(41psi).


My door sticker says 30psi all four, so even if I keep
them at 32psi, my tires are still 'underinflated' according
to some guv'mint gadget installed in them! So I
just drive around and ignore the light.

Mine have a calibrate button (in the car) that you press when the

I'd venture that's true in all systems that aren't actual
pressure...certainly was in all the vehicles I've had before the switch
to actual tire pressures (which I've found to be quite accurate and
reliable on all my GM vehicles).

The setting procedure was quite varied between different models and
years and manufacturers and some were extremely convoluted, but that's
the way they all worked.

That depends on the car and the setup. Some notify when down as
little as 2.5 PSI for sure - possibly some less.

Pat:

It's what the dealer told me. Like I said, I 'monitor' my own tires. Besides, how much gas does a tpms save when it allows tires to get 25% below recommended pressure?

If something's important, such as keeping up your tire pressure during fall to winter, you make the time for it, and get a decent gauge.

A good gauge can be had for a buck or two. I've been using a dial

mostly plastic, but it reads the same pressure as my stick gauges.

You can do better than the 25% but it takes work. Pump the tires up
to a value that is higher than your desired pressure and then press
the recalibrate button. Then reduce the pressure to your desired
pressure. In your case, you said that a setting of 41 causes the
warning at 32 - roughly 25% low. Just recalibrate the system at 38 or
39 in order to get a warning at 30.

You make a good point that these systems are not required. I have
always had a good gauge and used it regularly but as I get older I
like that if I get lazy and don't check for a while, it still warns
me.

Pat:

On the Kias at least the tpms needs to be dealer reset. And since I've had a dashlight since 2012, I suspect one of the units might be damaged or maladjusted. If I inflate my tires to at least 35psi, the light goes out. So it may not be a battery in one of the modules.

Motorcycle Consumer News, an ad free magazine, did a test of tire gauges a

type did as well as any.

I actually adjust my pressure down to 1/10th PSI. Yeah, it

Hi,
