What did David do that constitutes larceny of motor vehicle parts?

The action that constitutes larceny of motor vehicle parts is the act of stealing tires from a parked truck. Larceny involves the unlawful taking of someone else's property with the intent to permanently deprive them of it. In this scenario, taking tires from a vehicle without permission meets the legal definition of theft, as it involves taking physical property that belongs to another individual without their consent.

In contrast, borrowing tires implies permission from the owner, which does not support an allegation of theft. Purchasing tires at a discount is a lawful transaction and does not involve any unlawful taking. Similarly, repairing a truck with used parts, if done legally and with permission, does not meet the criteria for larceny. Thus, stealing the tires from the parked truck is the only action that aligns with the definition of larceny.
