So we received a message to please rewrite in English about the article of VALINO TIRES. I’m sorry if English not so well.
This article based on past article.
We wrote about the new tire manufacturers today.
New maker stand up in Japan, the name is VALINO TIRES.
These days, we get the information that famous D1(Formula D) drivers such as Naoki Nakamura’s are testing a new tire.
This is Varino (Barino?) Tire.
When I check the website, they says Japanese manufacturers. But they work only design and sales, producing countries is China.
Also it seems to be related VALINO with ZESTINO TIRE JAPAN company.
But products seem to exert a powerful grip than Gredge series of ZESTINO, it is easy to heat enven if in the wet condition. Even if there has over 500 horsepower, the power eaten by awesome grip of VALINO.
According to the SNS of Mr.Naoki Nakamura, a photo with the front of the machine lifted was uploaded.
This!
It seems that the design target field of the tire is DRIFT.
when I in charge of a ZESTINO Gredge series test engineering driver, I felt ZESTINO was easy to control slide but difficult to master the “true limits” of grip. It seems that VALINO is similar specifications.
Development testing of VALINO tire, Mr.Tetsuya Hibino is not involved. It seems mainly Mr.Naoki Nakamura has been in charge.
For now, VALINO has two brands, so called PERGEA 08R 08RS 08SP and GREEVA 08D.
High-grip tire is PERGEA, optimum scraping hard rubber to drift practice is so called GREEVA. High-grip PERGEA has three types of tread-wear(compounds), that numeric is 200,160,140.(08R, 08RS, 08SP)
（I tried and reviewed of 08RS.（Sorry, still Japanese. So pls press translation button.））
- PERGEA Series -
PERGEA series was designed to win match, such as D1 and the other drift events. Therefore, the race always starts with cold tread temperature condition, so the rubber is designed to be easy deflection.(But it is called the “hysteresis loss”, there has been touched on in past blog.)
In addition, not only soft rubber itself, it is also contemplated that immediately heat enters to win in the cold start also the tread surface is immediately softer.
Thus it is not suitable for use of several laps of the circuit(long stint run: heat up the tread condition too much is not good).
Conversely, there is good lap time can be expected in wet condition and winter short time-attack (like autocross.)
And the deep groove makes bad steering feel. If you use to time attack, I heard from engineer that good results can be obtained by shaving the tread to about 3mm of the depth.
- PERGEA 08R -
08R is the most hard rubber in PERGEA series.It is also good to heat, and even if it laps the short(middle size) circuit two times, the rubber doesn’t peel off.
Furthermore, in gymkhana(autocross, autox, solo), when we analyze the movie from outside both of them, the vertical direction is better than ADVAN A052.
But the side wall and tread rubber is too soft for the transverse direction.
Sometimes it makes disturb the car’s posture.
(If the groove will be shave to shallow, it might be solved though.)
The deterioration is less than other compounds(08RS, 08SP), because of the
tread surface’s melt is less than the other models.
So those who used in the drift, I think that this 08R is the most safe choice in VALINO.
If used in the grip, short time attack (about one to two minutes) without in summer and it may make you good lap-time than the more expensive tire if the wet road surface.
- PERGEA 08RS -
08RS is the middle model of PERGEA series.This model is further soften rubber than 08R. If you thought "I wanna a little bit more to the front!!" at the start dash of twin drift, you should be choice this model.
The rubber is softer than 08R, therefore also rise up the temperature of tread might be faster than 08R.
(No matter how good grip it has, not good tread rigidity and side wall rigidity is going to not good cornering. There has been touched in past blog.)
It is perfect characteristics in gymkhana(autocross, autox, solo) and wet condition lap attack.
But it is too soft, even if it is gymkhana in summer, it may not suitable for use…?
The price is not so different from 08R. It seems to be an awesome tire depending on the usage environment.
（I tried and reviewed of 08RS.（Sorry, still Japanese. So pls press translation button.））
- PERGEA 08SP -
This is the most high-grip tire of PERGEA series, the VALINO says.It has the most soft rubber in PERGEA, and it is not necessary to heat the tread before start, seem to exert a powerful grip.
Conversely, It is too soft to use time attack usage, and someone says that is only use in rainy game of DRIFT.
I have never seen(touch) this model, so I can’t review of everything about it. But in my imagine, it is only suitable for wet gymkhana or short-stint time attack in winter… maybe??
The first place , it come out only size for D1 vehicle size, the other vehicle such as small FF or light-weight vehicle can’t be installed.
- GREEVA Series -
- GREEVA 08D-
The rubber of GREEVA is quite harder than PERGEA, the model was developed with the aim that the against abrasion.It might be the same kind of concept of ZESTINO ACROVA series.
Perfect model for those who want good abrasion tires and want to practice the drift longer.
It might be a good for the city riding tire because it is hard to wear down in the general road.
GREEVA has not only big size(17 to 18 inch),but also has 15-inch size, so that can suitable for small car such as A to C segment vehicles too.
Those who has the purpose of how to use, VALINO is good choice.
Not suitable for those who are long running at the circuit(without GREEVA series), but is perfect for the purpose, such as "I want to win in the drift match" "I want to win in the winter and wet time-attack".
