I won't change a flat on my SUV. Too big and getting the spare tire down from the underneath of the vehicle would be almost mission impossible for me. DH showed me in case of extreme emergency how to put together the odd looking jack, find the hubcap key, even assemble the lug wrench but as long as I have AAA, my cell phone, and credit card or two usable feet, I'm not planning on saving money by fixing a flat on the side of the road by myself.
