Hello Graeme,
I am fortunate enough, or perhaps sad enough to own a number of Power Paks. I have found that the most important thing concerning tyre wear is to set up the engine so that it is square with the tyre, and adjusted for tension so there is no slip. Pumping the tyre up hard seems to help. Too much roller pressure will reduce performance, but I have found that the Power Pak has the best engagemment mechanism of the tyre rubbers, and has a really good adjusting arrangement. Power Pak supplied a guage with three feelers, one for plug, one for points, and one for tyre clearance. I have looked without success for one of these guages for years..
I have seen other cyclemotorists in trouble with wet weather tyre slip, whilst the faithful Power Paks have sailed serenly by. The tread pattern doesn't seem to matter much, and although modern tyres seem to be much softer than the were in the day, I have managed several hundred miles on the same tyre without a problem. I wish I could say the same for some of my other machines.
Alan
