Thank you all for your answers.
i get it .... because of the type of tire so hard is almost impossible bring it in temperature
Thanks Michal....
It is true .... I started very badly with this car .... I have modified the brake distribution to decrease the power in the rear ...... 
I have brought convergences to the neutral position because I could not put the car into the optimal curve ... ......  now I can have better the radius of the curve
I strive to brake hard in the straight and also reduce in the straight and I have managed not to lose the rear by braking ....... 
well.... now .....accelerating when leaving the curve is the most delicate ... ...when you lose it , it is very difficult to straighten well ....... what a bad pilot i am !!!!! ....... jajajaajajajajaj
