In the first place it would be nice if you could write in English. You can use the Google Translate for free, it should be good enough.
And there is how to turn on the particle GFX and skidmarks:

Step 3:

Step 4:
Click on the blue button in the top saying "Graphics".
Step 5:
Following window should appear:
To enable/disable skidmarks (tire marks), please check (click) or uncheck (click another rime) the box saying: "Enable skidmarks".
To enable/disale the particles (smoke, sparks etc.), please check (click) or uncheck (click another time) the box saying: "Enable particle gfx".
