otherworldly

I'm a little stuck... Click here to teach me more about this clue!

'like impractical thinker who'd roll tyre round' is the definition.
I can't judge whether this definition defines the answer.

'who'd roll tyre round' is the wordplay.
'round' indicates an anagram.
'whod'+'roll'+'tyre'='whodrolltyre'
'whodrolltyre' anagrammed gives 'OTHERWORLDLY'.

Can you help me to learn more?

(Other definitions for otherworldly that I've seen before include "Ethereal" , "focused on hereafter" , "Spiritual; imaginary" , "Out of touch with reality" , "Impractical" .)
