But the thing is I have a totally different perspective. And that is someone who doesn't back off their pace as their tires wear and age, is either (a) not really pushing it that hard in the first place, or is (b) an accident just waiting to happen.
An in-tune experienced rider doesn't even consciously "back-up" as their tires wear/age, they will just automatically adjust their corner speed back a notch or two based upon the feedback the harder worn old tire is giving them. This whole topic is really a question of 'feel'. Feel is inseparable from 'grip', it is just the other side of the same coin. The switched on rider constantly changes their pace based upon a whole set of variables including tire age/wear e.g. new or old (polished) road surface, dry or damp, etc.. And the bottom line is old hard worn tires do not (cannot) give the same level of positive feel back to the rider.
The reason I'm 'rabbiting on' with this aspect has nothing to do with the merits or otherwise of Angle GT tires. What I'm actually addressing is the commonly asked question of 'how many miles do you get out of a set of XYZ brand tires?' Answer: How long is a piece of string? Someone may replace their tires when the cords are showing, another person when they are down to the wear marks, another when the rear is sufficiently squared off. Me, I replace mine whenever I feel performance has dropped below a certain level. And that level is determined solely by 'feel'. The only reason for looking at the tire may be to establish what may be causing this performance drop e.g. should I run different tire pressures in future, etc. If money were no object, I'd fit new tires every month.
P.S. A good cornering cruiser, is that what is know as an 'oxymoron'?
