Tire's LongSlip vibrates a lot

Hey guys!

Motanum here with another question for you. If for some reason you’ve been following me, you might know I am making a [F Zero like game in UE4][1]. Today I have a problem where the car will vibrate while accelerating. It kinda gets pushed to one or the other side when I am only holding the acceleration key.

What I’ve found in the debug vehicle menu is that the tireLongSlip is vibrating alot alternating from positive and negative values constantly. I am not sure if this is normal behaviour.

This is a picture when I just staretd the race.

And here is another picture after landing in a jump. While I am in the air, you can see it is back to zero in those moments.

So, what is the cause of this problem? Is it actually afecting my car’s behaviour and constant vibrations? Some settings that might be useful.
