I am looking to upgrade from the stick tire size to 31's on my TJ. The local tire shop quoted me 500 for four kuhmo tires and America tires quoted me 500 for Hankook tires. I also found a set of used Toyo open country for 360 and used Bridgestone Dueler for 275. The thing is my dad feels like i should just replace my one bad tire with my spare and run it like that, because Im looking to enlist and would probally leave at the begginig of fall. His reasoning is that he doesn't want Tires that I put on now to rot away while I'm gone. My question is does anyone have any experience with any of these brands and is his reasoning sound or should I replace them.
