Locally at our track I Beams, Cross Hairs and Kaos are the tires to run (hardpacked with slim groove-loose dirt outside of groove). Small pin tires wear very quick. I have been running some old Crime Fighters LPR and they work very well (but now all but gone). On buggy many are running bowties. It is a shame that Proline does not have these offerings as in my area we would buy them.
