Why not run the Mickey Thompson Sportsman or Sportsman + ? they are a soft sticky compound so putting them on the front would work just fine on a road course . What would you run ? Hard compound tires like the radial T/A which are junk on the street never mind a road course ? 15 inch tires are only available in a few compounds and 14 inch are even more limited in options .
PS your first clue might be the fact that you can actually read Mickey Thompson on the sidewall of the front tire
