Thank you very much to UPstage and a special thanks to Vlad, who explained everything in detail and answered all the questions, it took me a long time to choose where to tire the car, and stopped at UPstage, only after driving on the road felt a tangible gain, the car went completely different.
In some places, even the consumption became less, in acceleration to 200 took about 8 seconds and this is on studded rubber.Absolutely no regrets.
