I loaded the game and it was there, idk if i pressed the wrong thing but now all i get is the pit control thing next to the speedometer. I then turned that off,now how do i bring the tire wear/damage hud back up?
The pitmenu and the damage overview are part of the same UI element. It is known historically as the LCD display. You can cycle the pages back to the damage overview using the 'LCD Mode' keybinding which if I remember correctly is bound to either Enter or Tab by default. On some wheels it may be bound as part of the profile (I think G25 has this to one of the shifter buttons). You will find it in the Inputs tab or the controller settings near the top of the list if you wish to set your own custom bind or check what your current profile has set. The pit menu page of the element will be switch to automatically when you either request a pitstop or enter the pitlane. You can switch back after using the same key mentioned above.
