[Closed] **** off tyre inserts 🤬

inflate the tyre minus the rimjob sorry rimpact, pop off the bead on one side the put it in.

fetted soggy pool noodle 😄

Or just use DH tyres

Sometimes they seem to resist all attacks...

We have used some washing up liquid on beads before to help get it in place.

Two pairs of hands helps.

(I know it's not helping, but we just swapped old folding Hans Dampf for a newer SuperGravity with Nukeproof insert on WTB rim and it took two of us, but full swap was under 2 minutes...)

Rimpact come in different sizes for different tyre sizes. Maybe it just doesn't fit?

Pedros tyre levers

I stopped using 'em, not just for this, I had a flat that was definitely stopped from sealing because the insert was stopping sealant getting to the hole and that annoyed the crap out of me. Might use them again if I do any racing, might be back at the mega next year and they were great for that sort of thing (had to ride out the bottom section on a very soft front and that would have sucked without the foam)

It’s the right size Rimpact I think but I will go and check. Only me around - the wife would probably refuse to try and help but even if she did she’d be as useful as a chocolate teapot.

Maybe a bit of washing up liquid might help when the tool arrives tomorrow (assuming Amazon do indeed deliver tomorrow like they claim).

My poppy short ish travel trail bike weighs 33lbs with exo casing tyres and I’ve not really had any issues with those or addix snakeskin apex / grid tyres to date. Would prefer not to add further weight / I don’t think it’s really necessary for what I tend to ride.

Never used inserts, probably never will. I've never done irreparable damage to a tyre during a ride for lack of an insert so when it eventually happens I'll just suck it up.

Warm the tyres, fairy liquid or silicone lube the bead.

It's the rims, not the inserts. I have two sets of wheels for my full suss.
One set is a bugger to set up tubeless without inserts (pro core). Tyres are just too loose a fit.

The other set are a nice fit and I can seat most tubeless tyres with a normal pump. Utter nightmare to get the tyres on with the inserts, even worse to remove.
I had to cut one to get it off again.

Thinking about it, I have a 2.4” Trailboss in tough / fast in my tyre box. I think I might throw that on without an insert.

I had the same issue and then did what howsyourdad1 suggested and the tyre went on the rim by hand.

I have the same rims, same tyre, and Rimpacts in a box waiting to be fitted... looking forward to it, thanks for the advance warning!

I'll try to remember to update this thread on the outcome, but it'll be a while as I currently have no need for them due to being on a no-crash plan after a recent injury.

Last time this came up someone posted a video of an American guy with his "trick". Solved everything for me and I *** hated putting tyres on before. Basically get as much on as you can then move back to the opposite part of the wheel and pinch the beads in as close to the middle of the rim as possible, and work your way doing this back round to the trouble section. You should then be able to get a bit more bead into the rim, then move back and repeat. It works because the centre of the rim channel is smaller diameter than the outside. Have gone from failing with metal levers to getting it on by hand, with a little patience.

Spent an hour fighting with a tyre change.

you were wise to abandon after an hour. i spent the best part of a saturday in this before abandoning, then the first thing i noticed as i set of for my sunday ride was that i’d fitted the tyre (without insert) the wrong bloody way around!

Last time this came up someone posted a video of an American guy with his “trick”.

this only works if the bead stays in place while you’re working round the tyre again.

It’s the rims, not the inserts.

and sometimes it’s the tyres as well!

Never used inserts, probably never will. I’ve never done irreparable damage to a tyre during a ride for lack of an insert

tyre and rim protection isn’t the only thing on offer from inserts. damping and traction/low pressure/ support are also offered.

I've used the same combo and had the tyre on in 15mins. Do what howsyourdad says, which is also what Rimpact say, and it's a much easier task.

FWIW I found the Dissector to be really flimsy compared to other exo tyres, so it's now in the spares box.

As rsl1 said that video is a game changer. Not sure what following comment re bead coming off means. There's so much tension by the time you're getting to the last bit there's no way it should come off. This method has worked for me 100% across a mixture of maxxis, Michelin and wtb on stans, E13, hunt and hope rims with cushcore, a.r.d and rimpact. Open a beer and prepare to be patient.

Also the cushcore lever is superb for getting the very last bit done and even more so for unseating (along with a bucket) after they've been on a few months.

Dont give up yet!

Why did you bother then?

I put the Rimpact in when I put a 2.6” slaughter on because it was lighter than anything else I’d had in there with not a lot of tread so I was worried I’d pinch it. There are a couple of nibbles out of the Rimpact so I think it has been doing something. Just thought I’d run it with the dissector as that’s fairly light too but I have given up.

In the garage gym this morning and whipped both the Rimpact and dissector off and put on the tough casing trailboss. Took just a few mins - job jobbed.

You have to get the bead into the middle of the rim to get the slack. When removing user tyre levers (Pedros my favourite) to push bead away from rim edge and into the centre of the rim. You need to push under the insert. When refitting it's the same idea. Get the tyre on as far as you can then work bead into middle of rim under the insert. Last bit will go on easily by hand.

30mm id rim with 2.4 rear tyre with heavy case and rimpact here. Sadly did not stop me massively dinging the rim on one side this weekend. Did let me ride back to the accommodation.

Also the cushcore lever is superb f

This. It's stupidly expensive for what it is, but works really well. I bought one after failing miserably to remove a Rekon+ with a Rimpact Plus insert from a WTB Scraper rim using Pedro levers and fingers. Just makes it all a lot easier.

tyres in the sun and watch the video. best to seat one bead then insert the rimpac, should give you room to get the tyre on then

That's actually the one tyre I've had which was split wide open in a rock garden. Even with the Grid casing they're so flimsy.

I've also slashed the side wall of a slaughter grid in rocks. Had the rimpact in then as well and rode out on it.

I think I still continue to miss the Elephant in the room with this of running proper tyres in the first place, with sensible pressures.

19psi in the back with the second heaviest casing specialized do. Sounds sensible to me. I don't think higher pressure would have stopped my ring ding on Saturday and without the insert I'd have been repairing it trail side instead of at accommodation with a beer.

I have found this tool very useful.

Eldest_oab dented rim (badly) using 2.4" Hans Dampf Super Gravity at 35psi tubeless.

He did same again with Michelin Wild Enduro with Gravity Sheild last week at FtWilliam DH, 35psi with tube in.

He's only 10st on a 170mm travel Rocky Mountain

Depending on your riding style and terrain, you can do some amazing damage...

Had the same problem with a 2.4 Onza Aquia, bead wouldn't stay in the "well" as the insert pushed it back out again as I worked around.

In the end I used a couple of cargo straps and tightened each one down at the point where the where I was working the bead in and shuffled my way back and forth between the 2 sides millimetre by millimetre. Used pedros tyre levers and my hands hurt when I'd finished.

None of which are actual DH tyres tbf Matt, which I believe Hob Nob is alluding to.

Can't always get the tyre you want, though. Like, I ran a Rockrazor snakeskin with an insert because I couldn't find the supergravity version. Now it's discontinued completely. Not sure if the dhr2 2.4 doubledown dual I want has ever existed, I thought it did but it's not on the website now. EXO+ version might be tough enough for me, was always scarce and now unavailable till 2022 (and also, bloody impossible to bloody google for)

Give up & ride with finesse?

Not that I can help you with technique there

Tyre inserts only exist because tyres are not strong enough. Light rims and heavy tyres, it’s the future!

To be fair I’m pretty sure my trailboss with tough casing will be absolutely fine for the riding I do and with where we’re going in North Wales. Was just less sure about the slaughter (hence taking it off) and dissector - which was why I planned to leave the insert in.

That 'secret technique' video is funny. There is a video on Cushcore's own website that shows correct technique for these things:

https://www.cushcore.com/installation/

It's made easier with their 'buttplug' as it's easier on the palms of your hands, and I tend to add more light soapy water to moar places earlier to help slip everything into place.

As rsl1 said that video is a game changer. Not sure what following comment re bead coming off means. There’s so much tension by the time you’re getting to the last bit there’s no way it should come off

my guess is that the insert was pushing the bead off as soon as i let go of the tyre.

these are tannus tubeless inserts. went on as expected ethel a bontrager se4 but the continental kaiser was not working. i measured the tyres s as having the same width when mounted.

i will definitely be watching that video and going at it again.

+1 for the video posted by @rsl1. That technique is a game changer. Still a graft, but I've never failed to install a tire + insert (never tried actual cushcore mind).

Good luck

I have a 2.4” Trailboss in tough / fast in my tyre box. I think I might throw that on without an insert

I took my Tough Fast rear Vigilante off for a wheelbuild and noticed no damage ro the Huck Norris, so I've ditched it for the time being. I've found my minimum tyre pressures over the years and always check I have these before I ride. As has been said above, attention to tyre pressure and a rear dual ply tyre should negate the need for an insert.

Are some inserts worse than others? I did a change last night from Butcher/Slaughter to Rekon+ front and rear, and while the rear (with a Huck Norris) was a little more difficult to release from the bead compared to the front (no insert), the difference was negligible and both went on with the same amount of elbow grease give or take.

+1 for the video posted by @rsl1. Not had a problem since.

Are some inserts worse than others?

they are. they also come in a variety of designs which makes some harder to fit.

some are strips that sit across the tyre at the widest point. other styles sit in the rim bed and are sort of mushroom shaped and almost fill the bottom half of the tyre.

the latter type provide support to the tyre (which means the tyre squirms less/not at all at low pressure) as well as rim and puncture protection and are said to add more damping to the tyre. the damping aspect is what sets them apart from DH tyres. they are also far less uncomfortable and wooden feeling than DH tyres in my limited experience experience.
