I was really surprised recently when I removed the rear wheels , and saw how badly worn the tyres were on the insides, I could not see this with the wheels on without actually lying down.
So from now on its on knees to check them.
The tyre on the Punto throws a point about should a car be allowed to be driven away from a Test Station.
A couple of years before retiring I was party to an argument between our Plant Manager and one of the company owners---the front tyres on his 7 series were bald , he had tyres on order for a few weeks but they were still on Back Order ,and he insisted on using the car until they came in. My Plant Manager was pointing out that not only was it dangerous but as Transport Manager he was responsible.
It was also surprising how often we would find cars/vans with bald tyres---all the driver had to do was call in any ats who would sort matters out. This was still occurring after we had to complete a condition form each 2 weeks.
