Greetings from Norway! Just tried to mount my new G-One 35mm on Stan's Grail rims on my second hand GT Grade. Will certainly go tubeless, but tried with a tube this first time.
As I expected, the tyre is really tight and mounting it on the rim took some effort. However, the problem was that I was not able to make the tyre sit properly on the rim/pop into place, even when going to 100 psi and using some soap water along the beads. Parts of the bead remained too deeply seated in the rim.
Have you successfully mounted G-One on Grail rims and may you advise me?
Hope you may share your experiences and help me out...
Have you tried generously spraying a soapy water mixture around the bead to help it slide on? Do this before you start to air it up when it is deflated. Regular dish detergent and water. Get it very wet dripping wet. Then try to pump them up. If still not popping on, what I would do is ride them a little at low pressure to see if they would go on/ loosen up a bit, provided they are safely mounted to begin with.
I see you tried the soapy water. There is another thread on here worth searching for about mounting, I can't seem to find it at the moment.

\nThis is a known issue with many tubeless tires and NoTubes rims. The rims have an intentionally oversized bead seat diameter. Can make seating some tires impossible, and may break the bead of others.
\nThere are better ways to obtain secure tire mounting and sealing.

\nThe Easy Fit will make no difference. The dimension of the rim is the problem and nothing will change that.\n\nNever use a NoTubes rim.\n\nThe best current tubeless rims are the WTB TCS models. Work well with most all tubeless ready tires and especially good with WTB tires (which will not even go on a NoTubes rim).\n\nPacenti rims also work well with most tubeless tires. Easy to seat and secure.\n\nMy favorite tubeless are older Bontrager TLR rims with the snap-in molded rim strips. Absolutely the most reliable I have used.
Happy to say that once the Grail was fitted with Notubes' yellow tape, the G-One 35mm popped on perfectly at the first try - using the excellent Bontrager Flash Charger, by the way. Tubeless, of course.
I've put the G-38's back on the ATR rims. They are a little big at the back measuring in at just over 39mm on the ATR rims. only a mm or two to spare. But they do roll so nicely on asphalt as well as gravel, sand, dusty rocky fire roads, hard pack single track etc.

I tried a pair of G-1 38's mounted on some WTB KOM i21 rims on my Search last night and decided that there wasn't enough clearance on the back. Are you finding them ok?

The lightest I've had my Search is 18.5 lbs which was also with Sector 28's mounted on Hunt 4Seasons. Have you made many component changes to get that weight?

I get a little tyre rub on the right side when I stand up. but I can live with it so far. They actually measure 39mm on the Reynolds ATR wheels. The G-35's would be a better fit.

Yes, Handle bars, stem, seat post, saddle, crankset, wheels (biggest bang for weight buck) and cassette and chain.
No issues so far. But it is a tight fit, so make sure the wheel is centered. Too bad it's QR.

\nAnyway, as I'm living in Norway, I've been running 45nrth Xerxes studded tyres the last weeks. The G-One will pop back on only in March, I guess.
I've got the Ridley back in action finally though I've been using 28s so far and, on Saturday, 25s for a road century. But I'm signed up for the Redlands Strada Rossa for this upcoming Saturday and plan to try the G-One @ 35c for the first time. I'm pretty sure I'm going to like them. I ran the S-One @ 30c last year and though they did ok I think the 35s will be better. And especially since the recent rains in SoCal have really done some damage to the trails.
When I bought my bike I tried to put on a wheelset w/WTB Nanos @ 40c and the rear went on but with very little clearance. So little that I didn't even try to use them. The bike was delivered w/Challenge GG @ 38c. I only used them for one, maybe two rides before going to Schwalbe and tubeless. So that is about the maximum size I would use.
Ok, a long winded non-answer. The short answer is haven't tried the 38s and as of now don't plan to as I think the 35s will be plenty for me. Most Schwalbes run a little big so the 38s will likely be borderline. They don't have big knobs however so that should help. My 35s are in the shop w/wheels getting trued but I can measure them later if you like (on DT Swiss XR 1501 wheels @ 20 mm inner). All my tires are the Microskin/TL variety as I only use tubeless when riding off-road. Another option is the Clement MSO, tubeless @ 36c.
I have the Ridley X- Trail as well and I am running the G-One in 35, tubeless and on a Hed Belgium + rim. Measures out at 37.8 (ish, depending on psi). I am happy. I will likely switch to the GravelKing SK when these wear out, but no complaints. I haven't had to deal with a roadside flat.... yet.
I've always been a fan of WTB and Vittoria tires, but the 35mm G-Ones that came with the Niner RLT are freaking great. They roll well on pavement and gravel, they have pretty good grip on wet pavement (a concern of mine, I think the tubeless psi really helps with that), and they fit easily with full fenders. I'm just hoping they are hard enough to last a few thousand miles before needing a replacement.
When I do replace them I will probably buy the 38mm version. It should still fit fine with the fenders, although maybe a little rub from fender rattle up front.
I'm not one for hyberbole, but this is an intriguing article.
Road.cc loves these: If you can fit the Schwalbe G-One tyres in your frame, you should get some. As genuine all-rounders they're impossible to beat right now: fast rolling on tarmac and properly capable off-road. They're really, really good.
CX said they were almost 100g over weight Bummer " Our 38mm-labelled sample weighs 540 grams and measures 37.5mm wide "
Still, it looks a lot like the Maxxis Rambler in performance and size (the maxxis are a bit smaller than advertized, and seem to match the G-one's actual size).
