Diomedes Motors has just decided to start using Rapilux Tires on most models of its new cars. The tires cost the same as the previous tires, and the change in tires will not change the sticker price of any car, nor will it change the profit on the sale of any particular car. Nevertheless, the CEO of Diomedes Motors expects this change in tires to increase Diomedes' profits in the coming year.

Which of the following, if true, provides the best reason for the expectation?

【选项】Some of the tires previously used on these particular Diomedes models are being phased out by those tire manufacturers, and would have to be replaced anyway, and no tire that would fit these Diomedes Models is any cheaper than the Rapilux Tires chosen.
