Is the Decorator pattern right for my task?

Question

Yii

You need to create a link between Car and Wheel. Relayshen add to Car will not work!!

/**
 * @property Car     $car
 * @property Wheel[] $wheels
 */
class Decorator
{
    // геттеры + сеттеры
}

class Car extends ActiveRecord
{
    public $id;
    public $model;
}

class Wheel
{
    public $color;
}

So far I'm leaning towards the Decorator pattern, but I'm also thinking about DTOs.
How right?
