Vanilla Rally tires have too much grip on dirt and tarmac?

I tried making new rally tire jbeam files if anyone wants to test them out and see if they make a difference.

Basically what i did was change the numbers in the groundmodel section from this:

//groundmodel friction multipliers
{"frictionCoef":1.05},
{"slidingFrictionCoef":1.15},
{"stribeckExponent":1.5},
{"treadCoef":0.8},

to this....

//groundmodel friction multipliers
{"frictionCoef":1.0},
{"slidingFrictionCoef":1.0},
{"stribeckExponent":1.0},
{"treadCoef":0.58},

Here is a video of the old tires. You can see the grip is so much he flips when exiting the top of the hill.


the logic is that the tread of these small rally tires are grooved but not as much as the bigger d series offroad tires. Can anyone confirm if these feel more natural?

To me it feels better but i dont have extensive offroad driving experience irl to tell if its really better.
