I got an exceptional deal on a set of new Mavic Allroad Pro wheels. These are UST and Mavic is vague regarding Tubeless Ready tire compatibility, and I did not like the Yksion's Allroad XL tread pattern, which is perfect for hardpack and dry gravel, but looks problematic for wet and more off-road conditions.
Because of the UST issue, I am currently testing with tubes. Next, since both the Mavic wheels and the Continental tires are theoretically usable without sealant, just for "fun" once some consistent bad weather arrives, I am going to see if the combination hold air without sealant, not that I would run such.
Ever since the GP4000s where released, I have had a fantastic experience with Continental Tires, which consistently test both fast and durable; however, they seem to be just about the most "controversial" brand. For me, time will tell.
I've been running terra speeds on allroads or crossmax slr's this season, and it's an awesome combo that inflates with a track pump and valve cores in and holds air for a long time without sealant. I'm really happy with my allroads.

They make great stuff, but the GP5000 TL is almost impossible to mount on a rim that is even minutely oversized, and the Schwalbe G-One allround is equal or better to the Terra speed in every metric that I can ascertain on my bike. I love those two tires, but they are not perfect for my use case.
Funny, I was thinking about this today. I love Schwalbe too; I have been using them for years on my MTB, studded and unstudded!
I think the issue with the Continentals is that ironically, there QC may make for smaller variance, hence the rim Manufacturer better have the same tight tolerance.
On my Mavic Allroads, the Continentals have the same mounting "ease" the stock Mavics. Thus, you need to go with what fits. In fact, had I liked the tread pattern that came installed with Mavic UST wheels, I would have stayed with them.
my mounting issue is only with the GP5000. It is designed as "high pressure road tubeless" with a very, very tight bead. I don't want/need high pressure (I'm on 32mm at 40-60psi). The terraspeeds and G-ones (40mm) mount the same for me.
I bought a carbon Cannondale Topstone. I took the high-end, lightweight handlebar, stem and seat-post of my road bike that I have not used in years, plus changed the saddle and got the SI cranks. I also lowered the stem. Thus, it is a very capable road bike with 28c Continentals swapped on -- another reason for running sealant in tubes.
When I do this, I hope you are not right....

No issues with my Terra Speeds since new, maybe 7 months. Just wish they were wider. G-One all arounds prob not an apples to apples substitute except maybe in weight and size. the recent bike tire rolling resistance test of the all-arounds was nothing short of scathing about how slow they are now.

If https://www.bicyclerollingresistance.com/cx-gravel-reviews/compare/continental-terra-speed-vs-continental-terra-trail -- I read that as the Terra Trails having a rolling resistance greater then Terra Speeds that cannot be explained by being more knobby. Compared to other true off-road gravel tires, the Terra Trails are right at the top. The speeds have the by far, lowest rolling resistance of any gravel tire, as the Panaracer gravel/cx tires are more like a wide, Four Season tire.
I think you didn’t read my post closely enough:" the recent bike tire rolling resistance test of the all-arounds ...” The new test was of the Schwalbe G-One All-Around and Jarno says they were super slow to the point where he is sure something went down the tube with Schwalbe quality control.
Schwalbe can be some quirky stuff, from the endless weird names for levels of protection and rubber compound, but Ive always found their tires to perform pretty well. So I hope he’s wrong...
There is enough test data out there on the Conti Terra Speed that there’s not much doubt that it’s super fast. I think of it as the fastest proper gravel tire, though Id be willing to entertain an argument that its flat protection may be borderline. Again, my only real problem with it is theyre too narrow for almost anything I do. If they were 42-45 they would be my go-to tire for 85 percent of events. As it is, they sit in the closet and I run Resolutes or Pathfinders, and swap out to Gravel King SK’s or MTB tires if there’s going to be serious sharp rock. Terra speed ideal for total hardpack courses, esp when there’s a lot of pavement, but not a lot more than that.

I've got both, I can't tell the difference between the two realistically. Apples to apples on my personal bike. Besides, that test (nor the tires) result was not available when I commented a few days ago, lol.
There is plenty of data showing the current set of G-Ones roll fine - a couple of watts on a drum doesn't make it a faster or slower gravel tire. But, if the new generation of G-One is as bad as that test from last week - well that is a disappointment.

I would agree that 5 (or even 10) watts per tire on the gravel probably does not make much or any difference which probably varies more with surface gravel type. Thus as you said, on a steel diamond plate drum, the results are representative. Moreover, this drum test meaningful for road tires. Really, rolling resistance only matters over long distances on the road, where a 10 watt or so more per tire difference may cost 15 mins over 100km.
Off-road, worry about grip and reliability.
PS -- I like Bicycle Rolling Resistance's use of a diamond plate drum as opposed to a smooth steel drum, but wish they would go one step further and add deck paint or something else to better simulate road and off-road surfaces.
About 250 miles ago I put on a set of new tires. 700x 40c Continental Terra Trail on the Front and TerraSpeed on the back. Tonight they came off. Two punctures that required patches, and so many small holes on both tires I’m loosing sealant and pressure, so I’m done with them.
Riding gravel roads I’ve ridden for thousands of miles, with no issues like this on other tires. Gravel is pretty typical Alabama farm roads.
Tried them because I like Continental road tires, but thin casing and lack of puncture protection did them in.
I have almost exactly the same issue (looking almost exactly like yours) with my 35 mm Continental Terra Speed TL (and running them tubeless). First I noticed they were rather large and a thus bit difficult to install when setting tubeless and now this. Worst tires I ever have bought in my life with a large margin and Contintental should be ashamed of this. They are so bad it's almost controversial I would say. I have only been riding about 300 km with mine. I have no other choice than using tubes together with these, remains to see how this will work... The person in charge for Continental Terra Speed TL should get fired. 🙃
I used to ride a pair of Terra Speeds in 49 mm, tubeless. Mounted them beginning of spring 2021, rode about 1500 km, then the bike was stolen.
Good things were that they rolled very fast and relatively silent. Also, the grip on even wet tarmac was excellent, in my subjective recollection significantly better than the Schwalde G1-bite (2020 version). However, the reason for this better grip became clear when I noticed the rear tire shedding material at a prodigious rate. The compound must be very soft. Regarding leaks all was well until I hit the 1000 km mark, then the rear tire started springing leaks, repeatedly. Not massive ones, just small, recurrent leaks like the ones pictured. I was worrying about having to replace it and how it would turn out to be an expensive experiment, longevity wise when a thief stepped in and solved that problem in one fell swoop (the bike was insured, I recovered 95% of the purchase price). Haven't gone back to them, mainly because there are other good tires that offer sufficient grip but last longer.

It has to be something strange with at least some of Terra Speed Tubeless tires, perhaps quality issues or a complete failure, that's all I can say. Worst experience with tires I have had in my life, feels like a complete waste of money. You will be able to find poor reviews for these Tubeless tires on other sites as well, Wiggle etc.
They may keep air for some days but I have no idea about how much sealant left since they have tiny leaks, I would have to refill every second week to be sure. I will probably run them with tubes for a while but I could end up buying new ones too. First I have to warn the site I bought these from.
About my 35 mm 1. Terrible fit (large) and thus difficult to setup for tubeless 2. My tires looking almost exactly now like the first pic in this thread, only been using them maximum 300 km, tiny sealant leaks all over the tire.
yep, pretty much my experience. 1000 km miles and they were iffy. Lots of leaking pin holes, and the center was smooth. Makes the GP5000 look like an endurance tire. ;-)

this is normal. The rear takes a lot of abuse under braking and when you’re pedaling while standing. It gets unweighted and slips a lot more than the front on the loose surface. Additionally, you’ve probably got 60% of your weight on it most of the time and 90% of your weight on it under acceleration.

I realize that but the rear wear seems much worse than I have ever experienced. Could be that the little nobbies provide a more pronounced indication of wear.

Bottom line, yes in the rear they will wear much faster than anything you have experienced.
With a front tire, I can go ~10 years and still have tread, typically. But of course by that point, the rubber is old, stiff, dried out, and crusty. Kinda like me on a bad day.
