It is bad for transmission if you have tires with different threads because of different contact with the road, so it is better to order the one you already have on the rest 3 tires and use different thread as instructed for donut. Otherwise you have a chance to kill your limited-slip differential so it become regular open differential or you might have TOD/ABS to fail in some cases.
