Part Worn Tyres are NOT worth Considering

Responded to a puncture repair yesterday and found two directional tyres fitted diagonally across the vehicle both facing in the wrong direction one of which was over 10 years old. Two bald tyres one so bad the air had escaped! Fitted two nice new Maxxis tyres to the rear and repositioned directional tyre with tread facing the correct way, reballancing the unballanced wheel. Talking to the customer she had recently had 3 part worn tyres fitted and thought her tyres were good except for the puncture of course.
