This is the second time I’ve tried these tires. This is also the second ride on them. Had a soft tire at mile 30 of 38. Filled with CO2, and it was flat again at .3 miles from home.
Last time to e I tried them I had incessant flats. I really do expect better from a 100 dollar tire.

You put sealant in? Or an inner tube?
What was the cause of the flat?
I feel you, I had a few rides where I had 2 punctures in the same ride.
They are extremely vulnerable to the tiniest stuff getting stuck in it. I once had 4 punctures in 2 following rides and I could really not find what it was. I must have knocked it out after the fourth time, because ever since, 0 issues.
Apart from that I find them vulnerable to damage. I replaced a few now for various reasons. Big cuts on the surface, the sidewall buldging, etc. And the last time I thought, if it is like this, I switch to other tyres. And what do you know, this pair seems indestructible.
But nonetheless I really like them.
On GP5000, my average with tubes is a flat every 300 miles. Recently switched to Tubeless, and have just reached the 300 mile mark and so far so good (knock on wood).
Have you been happy with your ICAN wheels? I have had a gravel frame and set of 650b wheels for going on 4 years and haven’t had any issues myself
I’ve gone thousands of miles on Michelin Power Cup TLR and had a single flat. Conti is notorious for this
Set up tubeless, I’ll get a flat or two per season, 4-5000 miles.
Literally over 15k miles with no full flats running tubeless.
Never flatted with these running tubeless
I’m using mine in Berlin with lots of glass shards. They are great for me. Very few flats.
So far the only time I’ve gotten a flat it was from having my tire pressure to low.
I run GP5000s with tubes, and I’m just over 3600km on my current set without a single flat. My previous set was just as good. They’ve always been pretty decently puncture resistant for me.
I’m not sure how people get so many flats with GP5000s. I’ve gotten one flat ever with a GP5000 and that was after I’d ridden it completely square before swapping it to the front. The roads around here are awful too, so it’s not like my tires are babied.
I use the AS tubeless. They aren’t as grippy, but they are pretty damn great.
What’s a flat?
You could try Pirelli Race tires. A little slower than gp5000 but more puncture protection with similar feel.
If it was soft, you already had a puncture. Of course it would flat out after you pump it up & ride more- the hole got wider with each rotation.
Pull it, do a deep inspection while pinching & rolling it between your fingers to find the tire’s hole and maybe also the offending road debris. If it’s wire, you may need to wait a couple rainstorms for it to clear. If it’s glass, don’t ride through glass.
You may live in an area where tubeless is the way to go as P-Zeros & Corsas will suck up that fine puncturing debris even quicker & more frequently.
I’ve run the GP5000 with tubes up parting with them as putting them on after having the change a tube was horrible; they are super tight. I also didn’t find them grippy enough for me..but, I didn’t get many flats and the roads in my city are horrible.
If you’re running tubes, you’re better off using the standard model (designed for tubes). The standard model also has slightly lower rolling resistance and less stiff casing, lower weight.
What are your road conditions. I’ve run the 5000 in both standard and tubeless varieties and get around 5k miles before I start flatting (which is the sign that it’s time to replace the tires). That usually lasts me a season.
Unpopular opinion: run inner tire liners. I rarely have a problem with punctures.
Now, getting the freakin’ tire over the rim on the install… that was two new levels of hell.
