how far do you push your tires before replacing?

[bikinchris]

How far do I go? Much, much too far. I usually go until the tread is peeling off and the cord is showing through and often after a flat.
Fixing a flat is easy and quick.
I'll mount a new tire and tube after coating the tube and inside of the tire with talcum.

Replace. ASAP.

If you can fix it, use it on the front wheel.

I use the same tires but 25mm X 700C. Generally I run 2,000 miles on the front and chain, replace the chain and the front tire goes to the back. Then when I hit 2,000 the back gets binned. I did replace a front last year way early since3 I was damaged and teaching me very well how to change a flat. $ days straight and the tire replacement cured the flat issue. I also do not repair my latex tube. If one goes flat I replace it with another.

I once had a bad fall after a tire went instantly flat. I was aware of the wear, but thought that I could keep using it a bit longer. No more. When they become flat on top I replace. The photos of yours are far beyond my comfort level.

My rule of thumb is that if I get a flat on more than 2 consecutive rides it is time to replace the tire.

the exception to this rule, is if I know I forgot to pump up the tire properly before a ride, this will be less of an issue now that I am not using latex tubes.

Based on the above criteria, I usually get about 2500-3000 km out of a pair of GP5000s before I get new tires. Had about the same luck with Pirellis and Vittorias.

That's my take on it too. Also save them for indoor rollers or trainer riding.

I think I would be more comfortable with it on the back than the front but I have a hill that I normally hit around 44-45mph on with not really great surface with a corner at the bottom. It is a combination of gravity and being really fat .

that makes great sense.

This thread has kind of motivated me to get some new tires.

Mine seem like they are not through the wear bars but they are squared off enough it is noticeable when cornering.

I think I replace on the early side partly out of safety and partly out of why not. I still get a lot of miles out of even quite racy tires.

With 25s, a squared off time gets replaced. With 30mm or bigger, I find that they don't square off but will wear down to the casing. When I see the cords poking through the tread, it's done. I think there is just enough variance in tread thickness to make one or two areas show the wear before the rest of the tire. I had 28mm Panaracer Race tubeless tires on my road bike a few years back while riding in Fredericksburg, Texas, and on my last day, I noticed the rear tire getting soft about 5 miles from my hotel. I made it back and was wiping the tires before putting my bike in the truck and the rear tire had white stuff that wouldn't wipe off. It was tire casing. I pulled the tire off and it wadded up in a ball. I got my money's worth, but I was lucky it happened when it did and not 30-40 miles out.

I know I probably have more miles on this tire (GP 5000 tube type) but it is making me nervous. there is a place where a little piece of fabric material is poking thru. the wear divots are still visible but I can see the casing in a few spots where there are small cuts. rubber is pretty thin. where is your comfort level when it comes to tire wear?

I would keep riding that tire at least down past the divots. It doesn't look that squared off either.

Any tire consists of a number of layers. The outermost rubber layer is *not* for keeping pointy objects away from the inner tube, it is there to provide grip.
So there is no reason to worry that the probability of getting a puncture increases when the rubber layer becomes thin.
