I have a personal issue with tyre wear. When it reaches about half worn, I take great note of every little movement it makes and as soon as I think it's beginning to act eratically, I change it/them.
This comes from my former love of Michelin tyres way back when. No matter which particular Michelin tyre I tried, I found they would have a personality change about halfway through its wear life, and on more than one ocassion I had the bike trying to step-out from underneath me mid corner and leaning reasonably well over,, which used to make me almost soil my pants on the spot. Man I grew to hate Michelins for this. I changed to other brands and they also had their own personalities but none were like Michelins and I have never gone back to them. For a while I loved Metzelers, then Dunlops, now Bridgestones. I like tyres which begin to slide and let you know they are starting to wear down, but the one constant thing is that I notice this "change of personality" in just about every tyre I ever used and about halfway through its wear,, with the single exception of the standard tyre which came on the VTR-1000, which was a Dunlop something. To be honest, it was not the best all-round tyre but I loved it. I knew it was getting closer to its "use by" date though, simply because of the fact that in the 10 months I had them on, they were taking longer to warm up over the months and especially from that magic half worn state onward.
Many people may disagree with me but I trust tyres in the first half of their tread depth, then begin to take particular note of their behaviour from there on in. Mind you, if a brand new tyre slipped and slid all over the raod from day one - out it would go too.
In short,, it really depends on just how far you are willing to let it go. I am a firm believer in thinking that tyres go OFF each time you ride on them, warming up then cooling down,, they slowly cook themselves over their lifetime and simply cure to the point of worry,, sometimes. Probably the best way to get the best performance out of any tyre is to ride them just the once until they are worn out then replace them. But, that's a really impractical way of looking at it, and you could be in for some extremely long rides - Hahahaha... The worst way to use a tyre is to go for short rides once a month, maybe 20 - 50 miles or thereabouts, thereby heating the tyres up enough, then letting them cool off again without using the heat for long enough to get stickiness vs distance covered.
I go by feel and NOT wear. I have learned in the past, not to put your lifes trust in a few millimtres of rubber. The idea is to stay upright and not to - like I have done - skid on your butt down the road beause of misplaced trust in the black round things beneath you......
