plug in type like those made by Chickenhawk that can be set to a specific temperature,
not tire blankets that simply retain heat.
I bumped in to a guy who swore by them for motorcycle racing. They are not cheap but
they seem to have two big plusses. By reducing heat cycles because the tires dont get cold
in between track sessions you may extend the sticky life of the tires. Longer tire life=
lower cost long term.
Second with tires up to temp immediately on track we might reduce excessive pace lap
weaving and first turn/first lap offs (or worse) due to poor traction on cold tires.
Seems like they would be especially valuable on cold racing days.
As I said earlier the commercial ones are not cheap but also looks like something you could
make yourself if you wanted to save a few bucks.
So whats the down side?
Just curious.
