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.
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.
It was too good to be true.Installed on air-cooled Porsche 911 (964) as well as Nissan Note e-Power NISMO SThe company was
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.
