IMO, I think that's a wise decision going with the Michelin LTX. I liked them a lot for a year round tire and wouldn't hesitate to put them on the current TV when the time comes.
I negotiated the same deal as you about the trailer tires... (Must be the same dealer
) My High Country came in yesterday and as I type this the Towmasters are coming off and BFG COmmercial T/A's are going on including the spare. Like I said above, I won't put another BFG on the TV but from everyone's advice on this board I know it'll be a good tire for the Monty!
