Rear wheels dont touch the ground

Hey guys i'm realtively new to AC modding, but i'm close to release my first mod, basically i took the RX7 Tuned car and edited the model and some eninge/suspension stuff, the car is looking good so far and works fine ingame, the only problem i have is that the rear wheels seem to float in the air a slight bit, can somebody tell me how to fix this?

 

tyres.ini most likely, new tyres don't fit the new model dimensions

 

Yes, tyres.ini. the tyre radius has to be fixed. You need to decrease it to increase the diameter.

 

Old thread I know but I am about to go crazy with this same issue. I have gone to extremes changing the tyre.ini settings and I have no changes to the look. the car is still floating.

I am changing the radius. I tried changing it to 0.38000 and nothing changed. Then I tried changing it to 0.08000 and nothing changed. I feel like I am taking crazy pills. what else should I be looking at?
