I think your tyre is probably too new to accurately show how far over you lean. I'm less than an inch away from the edge of the tyre, and that area on the PR5 is slick by design. That there is a recipe for aquaplaning while leaning over.Your wear pattern (for urban riding) looks much the same as mine.
I think we need to keep in mind that although Michelin has released the PR5, they have not yet released the PR5GT...
Granted, they probably design the edges with the mindset of "don't ride to the rim in wet weather" - but that's simply not practical for daily life. Based on the tread pattern, I won't be running PR5's on my bike. Best wishes to those that are braver than I.
The dust from my pic down the centre of the tyre is probably from the last few hundred metres.
GT tyres usually get a stiffer sidewall etc, but no real change in pattern, and I'm beginning to doubt if the PR5GT will be made. Even if it is, unless the tread pattern changes, I wouldn't be buying it.
I remember on the old PR2's years ago, the edges wore quicker than the middle - despite a 100mile/day commute. That's simply the nature of my commute.
