That is not a puncture as commonly understood. Thin tread does not contribute to pinch flatting, only to punctures from road hazards. And that is the same front or back. Besides pinch flats just shouldn't be a factor for you. They are too easy to completely eliminate permanently.

But then I will always have a partially worn rear tire, so it will have a diminished lifespan compared to just putting a new tire on the rear. Moving a half worn front to the rear means 3k as a front, and at the absolute best, 1.5k on the rear, meaning it lasted 4.5k miles. Left alone as a front, it's good for 6k. That "new" front will move to the rear with only 1.5k on it, meaning it's only 1/4 worn, and should last... 2k? Maybe 2.2k?
It's a hassle. I average just over 1,000 a month, so rotation seems pointless anyway. Same reason I don't clean chains anymore. They'll be dead within 12 weeks of installation, no sense in fussing over them.

You're right of course, as far as you take it. Yes, if you only own 2 tires, and both of them are the on the bike, and you're worried about finishing that 500 mile tour thru Europe that you're on because the rear is more worn than the front, then rotate them to maximize the lifespan of this finite pair of tires. Otherwise, scrap the rear tire when it's worn out and replace with a new one.
EDIT: Re-read your post. I guess I might ask though what constitutes or how do you figure out when the rotation is supposed to happen, assuming you have two tires both of which are not worn past a place where you'd want to use them (on either wheel)? I guess I'm of a mind that if I'm unsure whether a tire is prone to blowing out, on whatever wheel, then I'm not going to want to put it on either wheel.

I've re-read his post multiple times and I can't find the part about spoke breakage. You added that and it's why I quoted you. I see far more front wheel spokes busted than rear wheels. So I figured you had data to back up your claim seeing it contradicts my shop's experiences.

Never had a front tire puncture... I hope that lasts.
I wouldn't rotate, but that's because I'm lazy, and am not blasting down any mountains usually.

I never rotate. Once I have a clean build, I leave it alone. I just replace the rear since I get twice as much mileage out of the front as the rear. Why take a chance on damaging the tire or tube by removal and reinstallation?

I used to replace the rear tire and leave the front as is. I changed my thinking after a long nervous descent in pouring rain. I always put the best tire on the front now. The front does most of your braking and that other thing called steering too. I seem to burn through tires at the same rate.

With good technique, you should never pinch a tube while changing a tire. The security of a new to nearly new front tire at all time is a significant advantage and is worth the trouble and small pinch risk.

Lol someone forgot their Brandt
More Flats on Rear Tires by Jobst Brandt
My own personal data is 31,000 miles; 22 rear flats due to puncture, 1 front flat due to puncture.
ETA: same mileage and I've broken 4 spokes in the rear and zero in the front.

Is your image that of a Conti Gatorskin? Looks just like mine so must be a Conti something. I don't bother rotating front to back. But maybe its more due to my laziness than anything else. The wear indicators are good. In general, I just replace them when the middle starts getting flat. It can be left on longer. However, I had multiple flats with screwed up tire casing the last time I did that. So not recommended.

There are time I do rotate tires, though. I switch to GP 4 Seasons for the winter months and rarely wear them out during that time. So when I put them back on the following fall I always put the better tire on the back. But the summer tires, the 4000s? I go through at least two on the rear every year.

I agree with this. Having a newer tire on the front gives peace of mind and safety. If you are changing a tire in the comfort of your home or shop you should be able to take your time to make sure you don't pinch the tube.

Strange thing about some auto makers, though. My sister in law bought a Mercedes 300, and the tires are different sizes on the front and rear, so you can't rotate them. I've noticed that on a few sport sedans. Not so much with my Outback, though.
