Is there a valid reason to carry the extra weight of spare tire? Will roadside assistance show up with tire mounted to wheel and then change it? There is no way I could change it myself.
We're leaving for Alaska next week, so I located an almost new used tire and carry it in the bed of the pickup that I tow. It has a cover on the bed, so no problem. I had a friend making the trip a couple of years ago and the couple with them ruined a tire on the AK highway and they had a very difficult time finding a tire.
