I carry all the tools, Gen, air comp, impact wrench, wood blocks, ect. But the one thing that I didn't count on when I had a blow out in the middle of no where in Nevada was that the dang spare would not fit the wheel. Some where between the factory and the dealer, or someone just swapped out my spare for one that looked just like the ones on the ground, except the bolt hole circle was different. This may be only one in a thousand incident but if you have your tires off for some brake maintenance, I would check to make sure that you have a spare that fits.
