I too have the "full size" donut tire and the only way I'd give it up is to replace it with a AAA towing service. A can of sealant just wouldn't cut it. The last three flats (two seperate cars) I had all included sidewall punctures. No can of sealant will fix that. FWIW, these were all in-town issues too.

Twice I had AAA repalce the tire witht the spare and then drove off to a tire lacement center. Once I had to remove the tire and get a replacement mounted myself (before AAA). I don't want a car without a spare unless I have some type of roaf service to get me back on the road ASAP.
