There is absolutely no way you can run those without sealant.
I've put Conti GP5000 Tubeless on and then put them in water - air is literally pouring through the sidewalls and they are flat in minutes. It really needs sealant to plug up those micro-holes.
This post is so incredibly misleading. Do not, I repeat, DO NOT waste your time with GP 5000 TL's on Mavics Carbon UST Wheels. GP 5000's TL's are notoriously tight and Mavics tubeless UST system does not allow fitting them easily - and in most cases at all. Trust me I have bought four sets of 5000's and been to two different reputable shops! After I personally broke two pedro's tools... I have heard every potential hack - from hair dryers, oven heating the tires, you name it. We even tried to mount an older TL 5000 that had 300-500 miles on it. The UST system has a notorious narrow and shallow well. In some cases you'll want to order 25's not 28's depending on your bike. Trust me just buy the Yksion Pro UST 2's and call it a day. You will not run the risk of compromising wheel well and everything should run smoothly - it's UST for a reason. Best of luck!
I have had Mavic UST wheels for about 2 years. The Yksion tyres ride well but are very prone to punctures (got thru 6 tyres in 2 years). Tried installing GP5000 TL. Nothing like in video. Took 90 minutes for one wheel and a broken tyre lever. No way I will be able to fix these if they puncture and sealant fails on the road. Would suggest amateurs avoid tubeless- very much regret having switched.
This ship has sailed, but maybe trying the Mavic UST tyres would have been a good idea - feedback i've seen suggests they more or less go on just by hand (no levers), that lines up with my experience of them on Prime TLR rims (either hands only or a final, light tweak with a lever).
So often previously it's been a combination of tyre and rim that cause the issues - something that the new TL/TLR standard is hoping to avoid.
I had a horrendous time with Hutchinson Fusion 3 TL tyres and Bontrager rims, so much so that I bought a bead jack. That said, with those same rims with the rim strip in, I can barely fit Panaracer Race D Evos and completely gave up on GravelKings after about an hour - both clinchers, both i'd never use on that rim with that set-up. I use both fine on another rim, so it's not put me off tubeless and it's not put me off clinchers because one particular set-up is a bitch. YMMV clearly on this.
The Yksion tyres ship with the mavic wheels. The 2nd gen yksion were supposed to be more hardwearing but I found the one I had was ok to a point then it was off the cliff edge (I got 3 punctures in 2.5 miles and had to walk 3 miles home).
They were simple to fit and no messing around with rim tape. Also pumped up with a track pump.
You need a dynaplug (various models) or a stans dart to fix the punctures whilst out (or a home )
Would be great if Road.CC comparerd saying installing on a Hunt vs Stans vs Mavic
Solid gold replies. 10/10.
Conti and Mavic, two big names sharing a wealth of expertise and development, yet they still can't produce a combination that can be inflated on the road, using a mini-pump.
I'll continue to wait, hoping I don't die before it arrives.
Unless the tyre unseats, which it really shouldn't do if it's on a tubeless ready rim then it will inflate with a hand pump, I've done it myself plenty of times when I've had a puncture which the sealent has sealed up.
In the unlikely event that the tyre does unseat or it needs to be removed, for example booting a tyre with a large hole that the sealent couldn't seal then you can use CO2 to seat it back.
Of course when you buy new tyres you may choose to fit them on the side of the road using only a hand pump in which case I'd advise getting a garage.
I'm not sure you are getting the point of tubeless set ups.
I have the Mavic UST with Mavic UST tyres that they come with, they go on by hand and inflate with a standard pump, easiest set-up I've ever had with tubeless, I also have some Hunts which are great wheels but getting the tyre on and seated is a nightmare.
