 Even after an hour's riding with temps in the 40'sF (5-10C), my
rear BT020 generates very little heat.  I've run lower pressure
(37psi) and still lack grip.  What about lowering the pressure
even more to help the tire generate heat during cold weather?
Does the 10% rule apply?  Until I can replace it, likely with a
BT010 to match the front, I'd like it to stick a bit better.  Any
experience or suggestions will be appreciated.
