IMHO;
Buy the absolute best that you can get if you plan on doing a lot of traveling. And don't forget a couple of spares of the same size and correct wheels. A little precaution will pay you back in the long run. You might even buy from a widely placed tire chain so you can get tires serviced when on the road.
Here in the N.W. we have Les Schwab Tires centers all over, so that is the brand I use on ALL of my rolling stock(except my racecars) as I can get serviced just about anywhere.
