Tire pressure monitors (TPM) should be installed for safety reasons.

Porsche Tire Pressure Monitor (TPM)
Many Porsches of the last decade or so have been equipped with tire pressure monitors (TPM). TPM used to be treated as an option, but recently it has gradually become standard equipment, and now all vehicles are equipped with it.
If you get a flat tire, you get a warning like this.
Watch for "deviation" when inflating.
The system displays the air pressure in real time while driving and alerts the driver if the air pressure drops below a certain level. In addition, theThe good thing about Porsche's TPM is that it tells you how much more air pressure to add or take out, depending on the tire temperature at the time.It is.
Sometimes there are Porsche owners with TPM who look at the indicated air pressure and give instructions at gas stations, etc., such as, "Put it up to 2.8," but this is not correct.The correct instruction is to display the difference and say, "Add 0.2 more.Otherwise, the air pressure would not be accurate enough to take tire temperature into account.
I have written a detailed article on this area in the past, so please refer to it.
Air-cooled Porsche also has an external air pressure monitor.
While some 997 and later Porsches are equipped with tire pressure monitors (TPMs)Naturally, earlier air-cooled Porsches, etc. are not attached.However, having grown accustomed to constantly monitoring the air pressure in my recent Porsche, I am inevitably uncomfortable with not being able to monitor the air pressure, so I have installed an external air pressure monitor.
The retrofitted ones are installed in place of the valve caps, and I did not notice any wheel imbalance with them on either the 964 or the NISMO. Button batteries will last about 2 years.
I have a cheap Chinese tire pressure monitor that I bought from Amazon, but it is accurate to within a few degrees of accuracy compared to the correct tire pressure gauge, not to mention the temperature of the tire, and it is powered by a solar panel so no wiring is required. The system is powered by a solar panel, so there is no need for wiring.

Air-cooled Porsche gets a flat tire. What about the tire pressure monitor then?
The other day, I was driving down the highway in my air-cooled Porsche when suddenly a loud alarm sounded.
Only the left rear is at 1.9.
I checked the air pressure monitor in a panic and found that the left rear air pressure had dropped to 1.9, which is normal for a stock 16-inch 964 and is around 3.0 under normal conditions, and the difference between the right rear tire and the left rear tire is large. In this case, it is obvious that the car has a flat tire.
I drove slowly and managed to get to my destination, so after getting some work done, I took a closer look at the car in the parking lot and sure enough, there was a small nail stuck in it. The air pressure was still about 1.9, so I slowly made a pit stop at a nearby gas station.
I asked for a flat tire repair on the spot and it was taken care of, but if I hadIt is very frightening to think that I could have been driving on the highway without realizing it and bursting.Especially since it is rear-driven, and if it had been out of control, it would have been a free ride.
When I think about it, I am very glad that I had the air pressure monitor installed. Nowadays, air pressure monitors with good performance can be obtained at fairly low prices, so we recommend that those who place importance on safety install them.

It has been a while.
I had no idea that commercially available air pressure measuring devices were so advanced. I would love to try one out.
I always use a small compressor to make my own adjustments, but I'm having trouble keeping up with the rest of the information as I get older.
As you say, air pressure is the most direct and important indicator for us. I have always felt that the air pressure should also be indicated in test drive reports, which often talk about the feeling of suspension.
Porsche dealers often increase the pressure to near the upper limit of the standard at the time of delivery, but the TPM saves me and I adjust it on my own.
For some reason I've been very sensitive to air pressure since I was a student and always go
This brings back memories of adjusting the same machine on the stand of
Even now, when I start driving, I start by checking the air pressure, and if the left and right numbers are different, it reminds me of the feeling I get when the coffee I brewed in the morning is a little too thin. I am not usually a nervous person, and I have a very easy-going personality, so this is a strange thing, but if I had to say, I guess it is because I have always loved tires and wheels.
By the way, I am going to try the 992GT3, Touring Package and am wondering if I should go with the PCCB.
I look forward to seeing you and your wife's further success in the future.

That's right!!! I do remember the experience of getting in the car coming back from the dealership and thinking, "Hey, that's a pan.
Air pressure really affects the way a car drives...

Oh yes!!! That's amazing!!!
I'll ask my husband about the touring package PCCB ^^^.
(In some cases, I would be happy to write an article about it)
Thank you for your continued support.
Hello, M ina.
Is this a problem in F1? As has become a problem in F1, current technology does not allow sensors to detect accurate values.
It is recommended to honestly adjust with an accurate instrument when cold.
I also checked my car's sensors by measuring them first, and 2 out of 4 sensors have a different 0.1 indication each.
Also, I don't think the gauges at the stand are regularly maintained, so I don't think you can rely on those numbers either.
I haven't sent my maintainan out to Bridgestone recently either.
If it decreases, suspect a puncture, etc., and if it is not a problem, add it. For example, if you match one tire that is showing 0.2 short, it would be a good idea to match the other tires with that indicated pressure.
The sensor is not accurate to begin with, so I don't think it will match if you align it with the values on the car side.
For your reference.

Thank you! I see! I'm learning a lot of things I didn't know.
I would be happy to learn more from you. Please do keep us posted!
Hello.
My Boxster is also equipped with a factory-installed TPMS, which I have found to be very useful.
I once noticed a slow puncture thanks to TPMS, and when I cut the sidewall in a deep mountain, I drove 50 km to the tire store on my own after repeatedly "filling the tire with air using a compressor, then watching TPMS and driving until the air pressure reached 1.0 bar. I drove 50 kilometers to the tire shop by myself.
Incidentally, the TPMS sensors on each wheel seem to be powered by a built-in battery, but even after 7 years/180,000 km, the battery has not run out.
I am grateful (laughs).

Hello.
> Even when I cut the sidewall in a deep mountain, I repeated "filling with air with a compressor → running until it reached 1.0 bar while watching the TPMS", and self-propelled 50 km to reach the tire shop. Sometimes.
Amazing...! As expected of the Grand Touring Master, Mr. WATA, you had such a survival experience...!
> 7 years / 180,000km has passed and the battery is still dead.
I am grateful (laughs).
Wow it's amazing ！！！！
I mean, even more than the battery life, I'm astonished at the mileage over the past 7 years...LOL!!!!
