The appeal of all-season tires and the choice of new Pirelli tires

The tires on the Tesla Model 3 were replaced this time.

We changed to all-season tires for the winter, but this was not just a replacement due to tire wear.
I'm basically a non-sports car guy.All-season tires are best(except in areas with heavy snowfall and cold weather). We would even like to see all-season tires as the default for family cars and mobile vehicles used on a daily basis.

What are the characteristics of all-season tires?Can be used in any temperature, summer or winterThat is.

Typical summer tires are used when temperatures areGrip is extremely poor below 7 degrees.. Therefore, in winter, braking suddenly on a cold road surface, even if it is not snowing, can significantly change the braking distance. For this reason, in some European countries, it is mandatory to always install winter tires in winter.

Pirelli Cinturato All Season SF3 block pattern

I believe this concept is important in Japan as well.

In winter, they want to wear tires other than summer tires. However,Studless tires are not an option for me........ Studless tires are certainly superior on icy roads, but as a resident of an urban area in the Kansai region, where the recent mild winter has continued, I have less than 11 TP3T of opportunity to drive on such surfaces. Besides, studless tires have fatally poor drainage and grip on rainy days, are unstable on highways, and do not allow the car to perform at its full potential.

So we are pleased to announce that the newly introduced PirelliCinturato All Season SF 3selected.

In my previous Mercedes GLB,Michelin Cross Climate 2but this time we focused on Pirelli's new tires. Foreign reviews of this tire have given it a very high rating, and it is said to have almost no disadvantages.

Cinturato All Season SF 3 Features and Performance

Here are the international ratings for Cinturato All Season SF 3

1. excellent handling and grip on dry road
2. grips better than other all-season tires on icy surfaces
3. slightly inferior to other all-season tires on compacted snow, but above average performance
4. very high wet performance

Most of the snow falls in Kansai.Sherbet condition, practically wet road surfaceIt can be said that Under such conditions, studless tires have extremely poor wet performance. Therefore,Strong all-season tire, even in the wetI decided to choose the

Cinturato All Season SF 3 Features

My Tesla Model 3 has 18" wheels, so both front and rear are 235/45R18 size. When purchased online, they cost just over 20,000 yen per wheel,80,000 yen for a set of fourThis is quite reasonable compared to the 110,000-120,000 yen for the Cross Climate 2. This is quite reasonable compared to the 110,000-120,000 yen for the Cross Climate 2.

Actual driving sensation and performance evaluation

First, as for ride comfort, I was wearing them before.Almost identical to stock e-primacy.I'm not sure which one I'm wearing. If you don't tell me, I can't tell which one you are wearing. The only difference is whether the air pressure is set higher or lower.

As for road noise,Slightly larger than e-primacyThe following is a list of the most common problems with the "C" in the "C" column.

The ePrimacy was a very quiet tire designed for electric vehicles, but the SF3 has a slightly stronger road noise compared to the ePrimacy. However, the difference is less than 10%. This was especially noticeable immediately after the new tires were installed,After a few hundred kilometers and the tires were scuffed and acclimated, it was hardly noticeable.
In fact, this tire isLow exterior noise tires.certified, and the e-primacy is just too quiet, but it is quiet enough compared to ordinary tires.

As for handling and grip on dry surfacesOutstanding performanceThe ePrimacy had critically low grip, especially in the rain, but the SF3 tracks better on the road and feels "sticky". There is less misalignment when going around curves, and it feels more stable.

I drove a little too fast on the mountain roads, but for a Tesla Model 3 long range model.Sufficient gripfrom e-primacy.Obviously sporty and responsive.Understeer at high speed corners also seems to be minimal. However, when driving aggressively like a sports car, the grip is passable, but the block rigidity may feel a little weak.

Although a detailed evaluation of its performance on wet road surfaces is not possible because it has not yet encountered full-scale rain, it has no problem at all with a small amount of rain. In particular, it grips well on slippery surfaces such as steel plates at highway joints and manholes. ePrimacy found the tires slipping easily under regenerative braking in such places, but SF3 does not feel such instability.

In fact, the e-primacy wet grip labeling is a "C", vs.This time SF3 is "A"It is. It is hard to find an "A" in all-season tires. The difference is so great that just one level of labeling can make as much as 0.5 car length difference in braking distance in the wet.

Also, this labeling does not only indicate performance on wet surfaces, but also grip on dry surfaces.

Impact on Electricity Costs and Seal Inside Technology

Since these are not eco-friendly tires, electric costs are expected to worsen slightly due to their higher grip.

Detailed data is not yet available, but it will probably be several percent worse.

For an SF3 of this sizeSeal Inside."This technology is called "Puncture Prevention Technology" (PEPT). This technology is based on a special adhesive material applied to the inside of the tire that automatically seals holes and prevents punctures even if a nail or other object is stepped on. Unlike run-flat tires, there is no need to harden the tire itself, so there is little impact on ride quality.

The red part is adhesive.

However, this technology has increased the weight of the tire. The tire shop told me when I changed the tires that these tires are quite heavy. He said that they are not as heavy as run-flat tires, but are somewhere between normal tires and run-flat tires, or slightly closer to run-flat tires.

The increase in tire weight is expected to worsen electric costs and slightly reduce acceleration. Although the difference is not so great that it can be felt,I do feel that it has lost some of its nimbleness when accelerating.On the one hand, the On the other hand,The heavier tires made the ride feel more moist.In the past, the e-primacy was a bit too light, but this has been improved in SF3.

Overall Evaluation and Recommendation

Overall, Cinturato All Season SF 3 is ratedVery satisfactory tiresIt can be said to be the best of both worlds. While fully taking advantage of the benefits of an all-season tire, it also offers excellent grip and handling performance on dry roads. Its high wet performance is also worth mentioning.

Although there is an impact on electricity costs and a slight increase in road noise, this is more than compensated for by the safety and security it provides. In particular, the tire is well suited to Japan's climate, where the four seasons vary widely and rainfall is frequent.

With the owner of a Tesla Model 3,We highly recommend the Cinturato All Season SF 3 to anyone considering an all-season tire.With consistent performance throughout the year and no need to change tires, this tire would be an ideal choice for everyday use vehicles.

Finally, the use of all-season tires not only improves safety, but also helps the environment. It can reduce the environmental impact of tire production and disposal, and thus contribute to the realization of a sustainable automotive society.
