Tried all sorts, gas bombs, pumping like a madman and even my brothers compressor with no joy, just to make sure I wasn't going mad tried with an old Nobby Nic and it went up with the track pump effortlessly. I guess the Maxxis were just too loose, anyone any top tips so I can try again

I assume you're using steel beaded HRs?
they are the most difficult that I've done tubeless but not impossible. On that how-to site they talk about steel beaded tyres being a pain to get seated and the advise is to turn the tyre inside out for 20 mins or so to encourage the bead to spread more. Still, I tore most of what little hair I had left out trying to get mine on. Last weekend I finally got some kevlar beaded ones and they went up nicely.

Had a similar problem on my DT Swiss 5.1's but I was using the DT rimstrips. I got a presta to Schraeder valve convertor and took them to a local garages airline, they still took some blowing up, but managed in the end. Not sure if this would be any more effective than your Bro's compressor though. Maybe try a local tyre garage who will have a very powerful compressor?

I use wider rims than you, but I found I have to put a few wraps of electrical tap, a rim strip AND the tubeless strip (BMX inner in my case) on the rim and then use CO2 cartrides to get steel Maxxis to inflate.
A friend of mine uses neat washing up liquid and a track pump. He's a better man than me!
That's why I now use Specialized tyres...

2.1 or 2.35?
the 2.35 will feel horrible on 717's, 2.35 HR's are great for cornering, sticking them on such a narrow rim will just leave you with a heavy tire, pumped up hard to stop it folding over in the corners and without much grip.

2.35 kevlar beaded ones, they're not as wide as the 2.25 Nobby Nic's that I've just taken off. I'll try again tonight.

Defo +1 on the CO2 cartridges - a nightmare without them and lots of fairy liquid! I also used electrical tape plus the rim strip too. I'd bought a compressor which was useless and the CO2 saved loads of time and swearing. Good luck!

when you say you tried with a compressor do you mean a 'proper' compressor with a tank or one of those tyre inflator devices that you plug into the mains or 12v supply in the car? I've never had any problems using a 'proper' compressor with any highroller, I suppose the fact I've got a wider rim could me making it easier though (D521)..

I always found D521's a PITA tubeless, ex/en321's were fine though. Both with the same (rubbish) conti UST grvity tyres. Never tried my HR's tubeless (yet).

They feel ok to me.
2.35 kevlar beaded ones
Everywhere seems to recommend the wire bead versions, the kevlar might just be a bit too stretchy to seat reliably.

Ive made kevlar ones stick when they are new, but then struggled to get them to seat when they are a bit old. too floppy I think like you say. younggeoff - are your HRs brandspanking new ? if not you might be onto a loser

I had problems with getting mine up, (used 13 CO2 canisters). Eventually worked with almost neat fairy liquid, you want a really thick lather and it should work ok.

Brand spanking new, warmed them up first to make sure they werwe nice and pliable too.

Go down the petrol station - compressed air, normally free and endless supply, just remember to bring a valve adapter with you. Much higher pressure than CO2 even, and when you spill sealant all over the place it doesnt matter (If you can deal with the looks you get from motorists when you stand there with white fluid all over the place!)

extra soapy, soapy water round the rim makes a BIG difference, be generous with it.
fairy is best:)

Proper compressor with a tank, probably didn't use enough fairy liquid
Posted 1 year ago # -
I find that neat fairy makes all the difference. It seems to act as a very temporary sealant, slowing down the escape of air just enough to allow the tyre to pop up onto the rim and seal.
I assume you're doing all this with the valve core removed, much harder with the core still in.
I use a £50 halfords compressor and they go up fine every time now.
