Estimate the number of tires purchased annually by a large car dealership in San Jose, California.

Focus on breaking down the problem into manageable components. Start by estimating the number of cars sold annually by the dealership and consider the average number of tires per car (typically 4 for standard vehicles). Factor in the dealership's tire replacement business, including how often customers return for new tires and the average lifespan of tires. Use local market data to support your assumptions, such as the population of San Jose and car ownership rates. Be prepared to explain your reasoning and any assumptions you make throughout your calculations.
