More detail required.
What tweaker settings are not taking effect? What files did you edit, and how?
For the tyres, you're probably missing textures. There are two sets of tyre textures you can use, called "bridgestone" or "michelin". You choose between them in the performance file. In the GP4 Central Mod, I only use "bridgestone" to keep it simple, so every team has the same type of tyres in the performance file.
If you want to use both types then you need the second set of textures, with "michelin" in the name as well.
