Never had anything in my tyre before so im completely clueless as to what kind of damage im looking at;
I understand it completely depends on how long the nail is or whatever it is but any have a decent guess.
EDIT: My guess is its been there a few weeks (Had my MOT done end of april/beginning of a May as well as it was the last time i cleaned the car, Also had the cutch done just over a week ago but doubt they would have noticed then) and i've noticed no real drop in pressure so if its leaking its a very very slow leak.
