I thought the point of a TALAS was external travel adjustment:skep:
I think the OP is referring to the tire contacting the crown if he(or she) bottoms the fork.
Personally, I have had 2 floats and never came close to bottoming either.
I would say you should be fine...concensus on the forum is that Fox are fine, regardless of their dire warning (ie legal a$$ covering).
To check it, mount the wheel, fully deflate the air spring and compress the fork.
