yeah cold n wet so more psi in the tire..

if you were wanting to keep the shape of the tire'? and better Grip
wouldn't it make more sense to help them if it was cold by putting in more psi as the tire won't get as hot due too the cold and the air inside won't expand as much ..?
but when its hot less psi as there is more heat which expands the air inside the tire giving the tire the shape it should be ..
