Lon:
What worked for me was specific tire testing, taking temperatures
(looking for even across the tread) at a test day and during races.
before that, I depended on advice from fellow racers on similar and
dissimilar cars, estimates from the tire dealers and manufacturer, and
in the end, the correct results were achieved through temperatures and
confirmed with lap times. I bought a contact-probe pyrometer for a
little over $100 from Racer Parts Wholesale and found it well worth it.
You could be skating because they are too soft at 20 and you lose
contact at the center; that happened to me running Dunlops at 26. On
the Hoosiers, on my 2,000 lb car, I run 27/31 Front/rear cold and
achieved better times at WG than what the dealer's recommendations did.
