Unwanted surprise

Went outside to collect the emptied green bin and saw this!
Rang No1 son to check if tyre people would be open today.  He has kindly volunteered to come over this afternoon to deal with the problem.  Saves me ringing the RAC who I think might be a bit busy!!!
I think this is the one tyre I didn't have replaced in April.
Must have had a premonition as I had looked out my car folder ready to book it in for service and MOT in January.
