I feel your pain.... They use to offer a 37X13.5X16.5 in bias but don't anymore. I don't know anyone who has ran their radials either so it's hard to want to take a chance on $550 tires. I'm looking at some 36" Swampers when my current tires wear out.
With as little as I drive my TJ, I should go back to swampers. I saw today some great deals on the blem section today on some 33” interco’s.....and some 36” ones too.
