Problem with tyres

how come that only one tyre shows up in all the cars when i fix the tyre brand? (ex. michelin tyres show up instead of others having bridgestone)
only the cars in the second slot (car_mclaren ...) are the only ones that really switch tyres when they are changed??

is there any way that i can fix this so that i can use two tyre brands in the game?? O_O

You can edit the tyres with TeamEditor, you can select the brand and change it. Download link: [www.simracingworld.com]

If you want to use teameditor, there is an updated version 3.5 at realgpx.com, this editor is good for editing performance of cars and drivers and can change tyre brands for the teams, gp4tweaker is probably better for any other editing as you can vary more things for each team/driver - and especially wheel positions

i've already tried teameditor and even the camera position editor... it still turns out the same way every time... D:
