Hoosier or any other tire manufacturer could make a tire that would last multiple weeks, or maybe even half a season. There's nothing new about tire technology that would make this a possibility. AJ foyt won the Indy 500 on only one set of tires way back in the '60's. Will speeds go down because of it? Probably. The real reason why this won't happen is money. Tire companies can't make money selling a fraction of the tires they sell now. They need the tires to be as disposable as possible, so that you need to buy as many new ones as you can afford. In the end, Hoosier is in business to make money, not save the customer money. They don't do that by NOT selling as many tires as they can.
