HUNTER'S COLUMN — KART TIRE SERIES
Dirt Oval Kart Tires
Six columns on prep chemistry, brand wars, Hoosier outlaw rubber, and dual-format tracks. For seat, axle, caster, and gearing start at Kart Setup (not tires) →
QUICK CALL — DUAL-FORMAT TRACK TONIGHT
Kart night (6" bead, open tire): read bite → pick duro → Maxxis/Vega tree, Burris spec, Cobra budget, or Hoosier outlaw.
Micro night (10" wheel): check rule book first — often American Racer SPEC or Hoosier, no prep, duro floor ~45. Do not put kart prep on micro spec tires.
Full decision tree: Kart and Micro at the Same Bullring →
