Truthfully, I don't know - that's why I didn't add any more!!!
The interesting thing is that freezing the rubber to 200 below (I presume that's Fahrenheit, so it's 'only' about 150 Kelvin) doesn't do it any damage - you might think it would become so brittle that it would crack on being handled. So obviously low temps with the trailer static present no worry.
Then comes the question of what temperature risks doing damage if the trailer is towed. A quick Google search suggests that most rubbers have operating ranges down to -50 degF.
Maybe this is a question to ask one of the axle manufacturers?
