RPO ZUZ would be for the spare tire. XUZ would be the RPO for the front tires and YUZ would be for the rear tires.
Yeah, I know. I just grabbed the first code I seen. But, spares sometimes are different than the OEM tires too. I always thought it was weird that they did both front and rear tires separately.
