I did "carfully" read your posts and came to the conclusion that you just don't know what yer talking about. Not surprising as you don't own either product. To help you along, the tire inserts do fit inside the standard rubber compound tire (please see my pictures posted earlier to help you visualize this) and do most certainly require a tube. If you are referring to their tubeless tires, you need to refer to them as Airless Tires. Two different animals altogether. As I've reported earlier, the T/A foam tire liners do not feel smooshy, do not develop flat spots nor do they feel wobbly; this info gained from several thousand miles of me pedaling atop them. Take what I write with a grain of salt as equally as you do for the rider here who reported back a wobbly feel on his bike. For the benefit of everyone on the forum here, buy a couple of those airless tires, put a few thousand miles on them, then report back with your findings. Parroting other's findings as you did does not count, LOL.
And when ripping a person on a forum, always but always use spell check. It just defeats the purpose and it's bad form when you don't; amirite?
