Heat cycling for new street tires

["Craig M. Daugherty" <cmdaugherty@tyler.net>]

I have decided to buy new tires for autox, but since I must drive massive
distances to events on the same tires they will not be R compound tires.
Instead they will be high performance street tires with a treadwear rating
of about 160. I wonder if these tires need to be heat cycled to be
maximally effective or should I just put 'um on and drive? Any suggestions?
