Some one said that driving on the tires (assuming street car) for at least
100 miles them putting them away for 24-48 hours was an acceptable method.
Is this one method recommended? Lets see, 100 miles, average 50 mph. 2
hours. You just have to decide how much your time is worth I guess.
So the consensus is heat cycling by the Tire Rack is a recommended service,
assuming you don't have time and resources to do it yourself.
What are some of the accepted "manual" heat cycling processes?

Stephen,
TireRack is a loyal auto-x sponsor and has done a lot of
good for us. I
strongly doubt what you write here. Please keep this kind of
opinion off the
list.

I think you are wrong here as well. My understanding is that
its the gradual
increase in temp up to operating temp followed by 24 - 48
hour cool down
that is an ideal initial heat cycle. This allows the rubber
molecule chains
to be gently broken and then reform and align. An auto-x
does 3 rapid cycles
up to and possibly above the ideal temp. The resultant rapid
multiple
breaking and reforming of bonds probably does not produce a
long wearing
tire.
