Ok just been out to check.
Was below 32 so am guessing maybe 30
It's now on 36...
Upon inspection of the rear end look what I noticed
Borked the tail tidy and the bloody plate!!! Am sure it's taken some tread off he rear tyre too!!!! Argh!! Although saying that it was low anyway. Didn't get many miles outta that rear, 6k BT 45s I think ...
