Why you should heat cycle your tires

JG, I'm impressed that you know of (listen to?) Marketplace’s Kai Ryssdal. 

Where's the data? 

100% surely the factory could do the treatment far more cost effectively that even tire rack. 

I usually just go get them as warm as I can doing figure 8s in a parking lot or doing loops of a cloverleaf if I can find an empty one. Im not wasting a session and hauling tires to the track I can't use. 

I've been autocrossing for years.  I have never had tire rack heat cycle a set.  Is this as beneficial for autocross as well?  This would be on a 94 miata with new RE-71RS. I only drive the car to and from events.  My tires usually age past their time/become rock hard before wearing out. Save the 60 bucks or worth the money.

I've had Tire Rack heat cycle the last two pairs of RE71rs tires I've bought. One set went on my E Street Miata, the other gets mounted on my daily driver civic when I autocross or track it. 
 

Despite the fact that I've been trying to heat cycle my autocross tires myself for the past few years, I definitely think they're lasting longer and the grip is hanging on very well. I lost track of the number of street miles, track laps and autocross runs I had on the set on the civic, I log all of that with the Miata. 
 

The Miata currently has 65 runs on the tires and about 2000 miles. They were good enough at the last event that I finally raw timed one of my friends in his STR prepped NB2, and he was on a brand new set of RT660s. 
 

I ordered a replacement set for the civic before the Challenge since I was going to drive it for the annual Challenge track day, and was planning to finish them off. I jumped the gun on that, they still have a lot of life left after a full day of lapping the Firm.

I doubt the factory can make a business case for investing in the floor space, capital equipment, tooling, head count, and training required to pull this off at a price delta their customers are willing to pay.

In reply to Andy Hollis :

Thanks Andy, it's good to know that doing the heat cycling myself is effective. I found out that Costco sells the RE71rs, with free mounting, so I'm back to doing it myself. 

You mention not spraying them. What spray are you using when you do?

I meant to reply to this earlier, sorry. When running tires that begin losing grip if they get too hot, you can cool them by spraying water from a garden sprayer. 
Examples of tires that slow down when too hot are the Yokohama A051, Bridgestone RE71rs. 
It's not something you can do when running track laps. It's common practice in autocross, depending on conditions, weight of the car, etc. My front wheel drive car with the open differential and extra demand and weight on the front will heat those tires a lot faster. I often don't even spray the rears.
