Regarding the so-called tire repair kit which Ford provides, has anyone out there had reason to use the item, know someone who did, and if so, how well did things work out? On something like this, I am a bit of a cynic. It appears to be A "Smoke and Mirrors" attempt BY FMC for not placing a spare in the trunk. I have worked in the aviation world for most of my adult life and am a firm believer in "Murphy's Law". It appears the purchase of a spare donut tire and wheel is the only solution. If I decide to do that, does the molded plastic houseing below the trunk carpeting have a tire well below it, or is that space taken up by batteries? Many thanks for any inputs.
