Porsche 911 front tire replacement

First Porsche 911 tire change

This time ... for the first time, I changed the tires of the Porsche 911 base model Carrera 991 late model ...!

After looking at the four tires on the 911's bare Carrera, the two front tires were slippery.

No, I was surprised. The photos of the condition of the front tires and the people who saw the actual car also said it was "terrible" (laughs).

First of all, this is the rear tire that seems to be okay. Migi behind is like this ↓

And behind the fold ↓

Compared to that ... the right side of the front was like this. Oh oh. There is no groove ↓

Furthermore, this is the left side of the front desk. There are no grooves here either! ↓

So, this is Abnai, so I decided to replace the two front tires for the time being.

After noticing this "no tire groove", I was careful to run slowly, especially on rainy days, until I could secure and replace new tires.

Well, and.

This time, the mission of this "Porsche 911 tire change". No, it may seem like such a tire change is exaggerated, but for me it was really exciting and my first experience.

Bring 911 to shops other than Porsche Center for the first time!

Yes! What was so exciting was that this was probably my first experience of "being taken care of outside the Porsche Center".

Whenever I had a problem with Porsche, I immediately contacted the Porsche Center and asked for help.

Then, when I brought the car to the Porsche Center and said "please", everything was OK, so even if I do not know the details and difficulties of the car, I will leave it to you for the time being. Perfect when the car comes back to you! It was supposed to be.

However.

I decided to change the tires this time at a car shop that my acquaintance taught me.

Because it was cheaper to buy tires as parallel imports than to go through the Porsche Center even if they are exactly the same Porsche certified tires (I also check whether it is a new tire and buy it. I did it ~).

Even if I have a lot of trust in the Porsche Center, this time I was struck by the price ^ ^ I'm sorry ...

so!

Until now, I had managed to do something with "please" without knowing anything, but for me it was not "the first use", but "the first car shop other than the Porsche Center".

Hey ... no, pretty? Actually, it was a thrilling experience for me. Oh, I'm sorry for the low level story again ^ ^

No, but for me, who doesn't know the details at all, I realized for the first time when I was a little nervous that bringing a car to a place where there was no Porsche sales person was actually a very high hurdle for me. ..

Ah, I'm nervous. What should I do if there are a lot of scary people ... ^^ ← Where are you going (laughs)

Furthermore, the shop I was introduced to was in a certain ward in Tokyo that I hadn't visited yet, so I'm thrilled to get there ^^

It was a really good shop

I didn't know how crowded the Metropolitan Expressway would be in the morning, so if I left early, I would arrive 30 minutes earlier than the reserved time.

Even though I made a reservation for the first time in the morning, I arrived 30 minutes early, so I was fully prepared to wait until the shop opened, but this shop's older brother.

No, it's a really good person, and even though I arrived early without permission, he started working immediately without a disgusting face. And it wasn't a scary experience to bring a car to a car shop to the surprise! Naturally (laughs) ^^

Looking at the tires that became so slippery, my brother said, "It's pretty slippery ^^".

When I asked, "It's my first time to change tires, can I watch the work? (Shooting)", he kindly agreed, and I don't know anything. He was a really nice person who answered all the questions I asked very politely! !!

First of all, remove the tires from the state where the car body is slightly raised by the jack.

It was removed in various ways.

The removed tire looks like this. No, the more I see it, the less grooves there are (laughs)!

Porsche 911 Carrera Brake

Mr. 911 Carrera with the tires removed was like this.

What is this brake?

Even if you don't have tires, it's kind of cool! !! !!

I don't have a chance to see the tires removed, so I can look into various things, take pictures, and one person "he", "ha", "it looks like this". "It's a suspicious person." (Laughs).

Furthermore, there was a QR code on the sticker attached here ↓, so I tried to read it, but the spring interfered and I could not read it subtly. I wonder what that QR code would have been if I read it ... I'm curious ^^! !!

The caliper has the letters Brembo! Haha. No, I'm really impressed.

I thought that it was a customer who just came to change the tires, but next to my brother's work, I was impressed with "hoho" and "wow" looking into the place where the tires were removed. From my brother's point of view, I wondered if it was like "Is this customer okay ..." with the maximum degree of metamorphosis (laughs).

This is a shot that is hard to take ↓! !! Looking at the Porsche 911 Carrera without front tires from below (it's no longer anything but self-satisfaction (laughs)).

Remove the tire from the foil

Well, after the tires were removed from the car, I used this machine to remove the tires from the foil ↓

Set the tires on the machine like this ...

Somehow I inserted the parts between the foil and the tires ... (It seems that the foil may be damaged by a rough shop, but this time there is no damage to the foil! Thank you ^ ^)

Do you understand? When the machine operates, the tires will gradually come off the foil.

Guwan, Guwan feeling (what kind of feeling (laughs)).

Oh! I got it! !! !!

Finally the tire was removed from the foil. great.

The measurement result of the tire pressure sensor is flying with Bluetooth

Oh yeah, when I changed the tires, I told him about the valve caps of the tires, "I want you to use the existing valve caps as they are." This is ↓

How. Since the Porsche 911 measures the tire pressure and displays it on the instrument, this sensor is already attached, so including the valve cap, this can only be used as it is, so on the contrary It was said that it could not be changed (dare not).

Here again my simple question.

It was said that the tire pressure was measured at this yellow circle ↓, but this small part is not connected to anything by a line, isn't it?

So, I asked, "The tire pressure and other values are displayed on the instrument inside the car. How do you display the tire pressure on the instrument even though this part does not seem to be connected anywhere?" ..

The answer is ... what. "I'm skipping information with Bluetooth," he said.

Well, such a small part that is just a little attached to the foil constantly measured the tire pressure and reflected it on the instrument inside the car with Bluetooth! !!

Once again, I am impressed by the fine details of Porsche 911. Various parts are always doing their best in various places.

By the way, measuring the tire pressure and flying with Bluetooth seems to be sold in general, so it seems that it was possible to retrofit it to various cars. Hey ~.

YOKOHAMA ADVAN Sport 235 / 40R19 (92Y) N0

Yes, and once the original tires have been removed from the foil, it's finally time for a new tire. Yokohama Advan Sport 235 / 40R19 (92Y) N0 Porsche approved tires.

Wow, what is this groove! It was a tire with such a solid groove! !! I didn't think it was the same as I thought, "Did you buy a different tire from the one you used to have?"

Let's take a look again.

This is my 911 front tire ↓ Certainly this is terrible (laughs). I don't think it's exactly the same as the tire above ^^ Well, is this really the same? !! It's too terrible ...

By the way, I was so impressed that "Oh, it's totally different! There was such a groove at first!", And my brother said, "Still, a more general tire than this Porsche tire. There are more grooves in the tires. " It's true ~. This is also completely different!

Now, let's attach this new tire to the foil from which the old tire was removed. I will use the same machine again ↓

Roughly put the tires on the foil ..., do something ... (← I don't know (laughs))

After that, if you leave it to the machine, the sound of tires being attached to the foil on the way? The tires were attached to the foil with a terrible explosion sound like "Bang !! Bang !!".

By the way, this time, the banging sound made by installing the tires for 911 seems to be a relatively quiet sound, but from my point of view it was a surprising sound that I thought that my heart would stop ^ ^

Tire and foil balance adjustment

Once the tires are safely attached to the foil, why not set the tires and spin them around? ↓

When I asked him what he was doing, he said he was adjusting the balance between the tires and the foil. If you do not do this, it may shake from about 100 km / h.

Then, as an amateur, I commented, "Well, if you turn it around with this machine, it will automatically adjust the balance ?? It's amazing!" (smile).

Hi, this machine will give you the number of grams needed to adjust the balance, so it seems that you will stick the number of grams displayed there on the foil.

I was surprised because I couldn't understand the reason anymore. Was the tire unbalanced? To me who started to doubt ...

"No, it was still on! That's what I removed," said the older brother pointing to the floor.

Yeah. Did these things come with my tires? ?? ??

While my brother was removing the Grams from the foil, I was just looking into the brake part of Porsche, so it seems that I did not notice it at all (laugh).

No, anyway, my car isI wash myself by hand every time, and I always wash the foil thoroughly at that time.It is. However, I have never noticed that such grams are stuck together. So, I still can't believe it, so I checked the rear wheels that I hadn't removed this time.

Ah.

There was ... ↓

It was pasted normally. I didn't notice it at all! !! !! If anyone like me doesn't know, please take a look at your car's tires. I think it's pasted! !!

In the first place, when I washed the car, I only saw the visible part and did not clean it, so it seems that I did not care at all about the place where this gram is pasted. From the next time, look at this area more properly and wash it ... ^^

By the way, the invisible part is the inside (back side) of the foil. It's a big deal, so I showed you this too ↓ Wow, it's dirty after all. But, well, this is unavoidable ...

The new tires have been properly adjusted and given a new number of grams.

Mounting is double-sided tape. In the old days, when the quality of double-sided tape was still poor, it seemed that it would sometimes come off after a while, but nowadays double-sided tape is heat resistant and can hardly be taken off, so just attach it with double-sided tape. , It seems that it is almost OK. The evolution of various things is amazing.

Well, when I arrived at this shop in the morning, I was ignorant who didn't know much about tires, but by the time I got home, I had a little more knowledge ^^

Thank you for your brother. Thank you! !!

The tires have been completely replaced! !!

Shiny. It's a waste to run! ... and I want to run faster ^^! !! How much does the sensation change when it's slippery so far?

Porsche certified tire called N0The number of is also included perfectly. Even so, the tires are beautiful.

Even when viewed from a low angle, all four wheels have returned to the state where the tires are properly attached. Seen from this angle, 911 has a strange face and is interesting ^ ^

This completes the tire change! !!

I thought, "Thank you!", But after that, my brother said, "It's Porsche 911, isn't it?"

There was a specified torque value for retightening

This time, he tightened it with a torque wrench. And here is another question. That is, "Why did you bother to comment that it was 911?"

So, when I asked ... what! !! In fact, even for retightening, the "specified torque" is determined by each model, and it seems that retightening is done with that value.

I was surprised again.

No, the manufacturer / dealer suddenly came in front of the driving event, and it was a mess! WhatThere were times when he tightened it upHowever, I was wondering if it was just "tightening up to the point" like a screw.

No way, there was a prescribed number for each car. No, there are so many things in the world that I really don't know (I'm the only one (laughs)?). It was a day that I really learned a lot.

Finally, enjoy Porsche's brake again ...

Oh, everything is beautiful ...

Occasionally, it was a day when I thought it would be nice to be able to learn a lot from being taken care of outside the Porsche Center.

It doesn't mean that you can't learn at the Porsche Center, but that you can make tea with a PC ^^

Oh yeah, one last thing.

My brother had put out something from somewhere in 911, so when I asked him, "What did you put out?", It seems that it is a nut for preventing theft of foil. Hey, that kind of thing was in such a place! !! I didn't know at all.

No, it was a day where I really learned a lot. Thank you for your brother. I would like to take care of you again someday ... How.

Fufufu ... I think I'll see my brother soon ^^

After all, when I said, "The front has become slippery, but the rear is still okay, isn't it?", My brother looked into the rear tires and took a closer look.

"No, it may look okay at first glance from the side, but the rear is pretty bad as the front!"

Ooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo Really! !! I couldn't tell at first glance, but when I looked into it properly, it was actually quite slippery! !! !! So, in the near future, I'm planning to have the rear tires replaced.

Ah, if this is the case, I should have changed four at once ... Well, I wonder if it's okay because I can experience tire replacement again ^ ^

It was a great learning experience and a fun tire change experience.

And from the way back, I was able to run on a rainy day after that with new tires without any problems. I don't know the details (laughs), but I feel that I feel more "sticking to the ground and running" than when it's slippery, so I can accelerate with confidence (oh, at legal speed ^^).

After playing a little more, I would like to change the rear tires as well!
