make one plane on the surface of your base extrude. apply extrude command on that new plane. if that doesn't work then make a distance plane from surface, put distance of your extrude grip on tire, start design from new plane and extrude till surface. one of this option will works perfectly. if you will try to do extrude directly from the surface, it might b fail because of tangent face of main body will not attach properly with your new extrude.
