Very extended treadlife is definitely possible. The problem is that you will not like the tradeoffs. This is vastly oversimplifying, but the overall tradeoff is grip vs durability. You get a very grippy tire made for racing in series that mandate street tires, and these will typically have both a very sticky compound and low tread depth. They perform great, but may last less than 15K miles of street use (or less than 20 miles on the racetrack). On the other end, you can get what are essentially hockey pucks that'll last a very long time in normal highway use. Depending on what you want to optimize for, you can start with several ratings on the tires themselves. Tire Rack has a great guide here [1] on treadwear and traction grades. It is a good place to start, and then you should always seek more detailed knowledge from people with direct field experience, as the ratings can be a bit games (e.g., you'd want to get some kind of AAA-traction rated tire for an autocross or track day, but getting the best one for your car, driving style and that event it'd be best to also talk to/read articles by people who've been there & done that) [1]https://www.tirerack.com/tires/tiretech/techpage.jsp?techid=48& https://www.tirerack.com/tires/tiretech/techpage.jsp?techid=...
