The above will repair the rest of the tires something Dokins doesn't want to. You can use something like this:

pawn Code:

enum Tire_States
{
    NONE,
    BR,
    FR,
    FR_BR,
    BL,
    BL_BR,
    FR_BL,
    FR_BL_BR,
    FL,
    FL_BR,
    FL_FR,
    FL_FR_BR,
    FL_BL,
    FL_BL_BR,
    FL_FR_BL,
    ALL
};

F=Front,B=Back,L=Left,R=Right, ALL and combination of the previous for popped tires and NONE for inflated tires.

and then do:

pawn Code:

(Tires | _:BL)

That will keep the same the other tires and pop back left.
