Sal...lo siento for les troubles, hombre.
You've commented on the leaking Big Letters more than a few times. I'm on my third set and never had one leak a pound even when sitting for a month or so during the winter.
Really think you've got a wheel issue...asspecially given the spare/BFG.
No flat-fixer can(s)/air pump/plug kit? I drive hundreds of miles in the Cobra with that stuff in a kit with no spare or jack. Never needed them...but they are there and take up a heck of a lot less space.
