Textures problems

[Diatosta]

Hi guys! So today I was trying to convert a car to MM2 (Yey for me ). All went fine, putted the car in-game, and the wheels look badly when they move, like they change colors. Do anyone knows why it is doing it? Go from very white to almost dark and white again, every time they turn, like they are damaged, but they're not :/

Here's a .gif of it:

That's not a textures related problem, it's instead related with the normals of the wheels 3D models. Does it happen to all the four wheels or only to those two? It happens when you flip the faces of an object but then you don't calculate the normals, but risking also to ruin the look of the model.
