One way can be:
Maintain 4 Measuring Points Tyres 1,2,3 and 4, where you'd maintain the Tyre serial number in the Measuring Document Text. At any point of time the latest 4 MDocs will show the Tyres (Serial Nos) presently installed. When searched with the Serial number in MDoc text, you will be able to know in which Equipments this Tyre has passed through.
