Cool hubs warm

[Cooper]

I have Cool Hubs on my Ranger trailer and after driving for a couple of hours the hubs are warm to the touch. Is this typical or should I be concerned? Thanks in advance

The tires generate heat while running on the road, and this heat is transfered into the wheel and bearings. So I'd say warm to the touch would be normal.

I agree. Not being able to hold onto the hubs for several seconds-be concerned.

I agree with the others. Expecially if you trailer brakes. The brakes alone will generate enough heat to warm things up.
