I measured the tread on my tyres and compared them to the spare unused Primacy 3.
The front tyres if run them to 1.6-2mm will last 20-21,000 miles. The rears should last 40-42,000 miles as they seem to be wearing at exactly half the rate of the fronts. The rears seem to be wearing at a similar rate to Grumpies.
The fronts are disappointment as I am a very gentle driver who spends long periods on dual carriageways and motorways. As I mentioned in the other thread I believe that the rubber used on the Primacy 3 is quite soft so that may well be a factor.
