I'm looking for some recommendations for tires that can would make good HPDE (track day) tires. Must be a street tire (no RA-1s), hold up to sustained heat without greasing, and have reasonable wear characteristics. I have been using Kumho MX's previously and really enjoyed them but I'm doing some research on tire/wheel sizes for a track only combo and the MX is a bit limited in sizing for 16". However don't worry about limited tire sizes in your recomendations, I'm exploring all options. Thanks.
