I carry a small aluminum floor jack, one of the cheap ones from Harbor Freight.
I also carry a quality plug kit(the rope type plugs, not the rubber ones), some quality glue and a bicycle air pump or small air tank.
And I never go anywhere without a good selection of tools.

If the above fails, I have AAA Plus, 100 miles free towing.

Fix a Flat works well on small pneumatic tires that leak down in days. I got tired of airing up the lawnmower, wheelbarrow, yard cart and hand truck tires every time I used them. Fix a Flat keeps them up for weeks instead of days, the quicker the tire leaked down, the bigger the shot I gave it.
