Tyre, oddly, has more than enough tread (7)
I believe the answer is:
trample
'tread' is the definition.
('trample' can be a synonym of 'tread')
'tyre oddly has more than enough' is the wordplay.
'oddly' means one should take alternating letters.
'has' is a charade indicator (letters next to each other).
'more than enough' becomes 'ample' (I've seen this before).
The alternating letters of 'tyre' are 'tr'.
'tr'+'ample'='TRAMPLE'
(Other definitions for trample that I've seen before include "Tread heavily" , "Crush by treading" , "Flatten" , "Step on" , "Tread on, crush" .)
