Tips to fit a tire on a tight rim

General

Good advice here. I am planning to buy one of the carbon rims soon and use the night rider light as well so I am curious to see the outcome

What rim tape do you have on the rim Maxence? You should be using thin tubeless rim tape, if you don’t have any you want to put on 2 wraps of insulation tape. You don’t want any rim tape on the seated area.

For fitting the key point is putting the tyre in to the middle of the rim. You want to keep squeezing it in to the centre all the way around. I was able to fit several night riders on to the carbon rim with only the slightest use of a tyre lever and think if I was really stuck could have done it without one at all.

3 C-clamps pinching the beads of the tire together at 4:00, 6:00, and 8:00.
Pinch the bead by hand at 9:00 and 3:00 and work your way up to 12:00.

I use the rim tape that came with my Nimbus Oracle 36 3 years ago. It was probably not the best idea :pensive:
I went to a bike shop and the guy succeeded in fitting the tire… But he damaged the bead so bad it does not stay in place anymore. I think I’ll need a new tire and a new rim tape… Roger, do you know if UDS DE will have stock at the same time as UDC UK? It’s easier to get stuff from there since Brexit.

Depending on the spoke tension you might be able to get some more clearance by increasing it. Tighter spokes result in a smaller rim. :wink:

Sorry to hear that your tyre has got damaged. You may find it is still useable on the Stealth II rim. It was designed to fit the Nightrider tyre and has a deeper clincher system on it.

Yes, Germany and Sweden are getting stock in July.

My rim is still not true but the shop guy told me it was not an issue to fit the tire. But I tried to tighten it before with no success.

That’s great news! I’ll try it tonight. I still have my first wheel built with its own Schlumpf hub. Maybe I can still have a working 36er then.

Another great piece of news! Thanks! :slight_smile:

Maybe the tire will still work. The original nightrider tire does not fit correctly on the stealth rim without carefully adjusting/centering the location of the tire on the rim when installing.

Even some damage to the tire bead may not prevent the use. On this tire that popped off the rim and damaged the bead I installed a new 29" tube and have put several hundred miles on it with no problem.

I tried to put the tire inside its original rim - a Nimbus Stealth2 - but it popped out as soon as I inflated the tube. Sadly, I think the tire is now out of order. It already had a lot of km so it’s not a great loss but it’ll take some time to replace it due to the current shortage… :frowning:
Thanks all for your tips and insights! :slight_smile:

For tight installations, I use the Kool Stop Tire Bead Jack. It’s effective for even the tightest situations. It doesn’t damage the bead, tube and rim.

I also have the Crankbrothers Speedier Lever, which works a lot faster but it can’t handle very tight installations.

Maxence you can try to set it tubeless with an half split tube ghetto setup. The side of the tire will still be compressed by the butyl side of the half tube

Good to know. I have a similar tyre after a blowout.

19

Can I take this back… the tyre factory delivered the tyres with over 100 missing! So currently no spares are being shipped. We are trying to rush another batch through and LCL them to Europe somewhere…

20

Does this mean you now have a few stocks in UK? I thought they should arrive on July.
Anyway, bad news. I’d get from UK if it does not into EU otherwise.

21

No stock in UK either and they wont be spares on our container either. :frowning:

22

Really bad news :frowning:
Does that concern only Nightrider tires or King George tires too?

23

Just the nightriders

Thanks for the info. I’ll wait for a King George then. As I have two 36er to build, I’ll build the second one later with a Nightrider :slight_smile:
By the way, good luck with your tires issue. Hope it’ll be fine as soon as possible!

I installed a 36 TA tyre on a CF rim last week-end for a guy who never built a unicycle, and I had no issue, just need to use thin rim tape and put tyre bed in the middle of the rim.

Yes, I think my mistake was to try to use the default Oracle 36 rim tape. With a correct rim tape I have a lot more space to put the tire in it. I now just have to find a new tire :sweat:
