interesting topic hear and just intime, I noticed after towing the horn about 200 miles I stopped at a rest area to get some snacks out of the trailer and kinda noticed a rubber smell as I entered the trailer, I put my hand on the tire, it did seem warm but not hot. Is this normal ?? or something I should pay a good deal of attention to. I do have the GY G614's Thanks, don't mean to take over this thread though, but figured it would be a good place to start.
