So below about 45 degrees, my "ultra high performance" summer
tires become much less grippy.
I've used the old BFG drag rad's @ the track on my Capri and a newer
set of Nitto's on the street (same car).
I've never raced though in really cold temps. Do the new drag radials
react like summer tires, in that there is "some" temp where the lower
DA gets negated by the low temps and ultimate tire traction?
Or do you just heat the crap out of them and the lower outside
temps don't really matter (except helping power, theoretically).
This all assumes the other factors that play into DA are equal.
Funny I was playing with this

calc simulating Atco and got DA's of
temperature: 55 deg f
humidity: 45 %
barometer: 30 Hg
elevation: 88 ft
density altitude: -88.830 ft
temperature: 45 deg f
humidity: 45 %
barometer: 30 Hg
elevation: 88 ft
density altitude:-833.127 ft
That's a huge DA change for only 10 degrees, but again
only useful if it does not start to degrade traction.
