Just change line 13 to: 
Actor a = getOneIntersectingObject(tire.class);
If you really needed the reference specifically as a tire object (which you do not), you would then use: 
tire a = (tire)getOneIntersectingObject(tire.class);
where a tire object (or '(tire)null') is set to a variable that accepts a tire object (not a Car object).

use 
if(isTouching(Tire.class));
instead of lines 13 and 14

If you make this change, it should be: 
if (isTouching(tire.class)) {
It is customary to have class names begin with an uppercase letter, which is probably why Nosson1459 made it so. But, the semi-colon at the end makes the 'if' statement all for naught. It, the semi-colon, is equivalent to '{ }', an empty block of code. The following statements will execute regardless of the result of the condition of the 'if' statement.
