Seriously I cant believe people are that worried about flat tires. How many have you had in a lifetime? I mean think about it. Real life is not like the movies where you get stranded in a desert and have to walk a hundred miles to civilization. I have a cell phone and will call to get a ride back to my house and pick up the spare. Unless you are an off-roader type or are constantly far away from any help its basically the biggest waste of space ever put in a car so why not take advantage of the space something that you will use everyday vs. once.....maybe. Besides Im running run flats too.

Bass > spare tire =
