Squid'nserts and Tusks, tyre "crumpling"?

[ferp420]

the insert moving around has nothing to do with anything thats fine leave it be the problem is your rim isent clamping down on the tires bead different tires have different style of beads and there is not 1 rim that fits all tire beads the superglue builds up the tire bead making it thicker it wont stick to aluminum for long any way but if you let it dry the super glue acts like teeth biting in to both the aluminum and the rubber holding it in place other than that i would say try a different tire or wheel cause your tire bead and your rims beadlock arent playing nice together

also if i remember right the boom racing wheels were designed to work with prolines fat ass tire beads cause at the time everyone complained about the tires being to hard to mount if i remeber right there were 2 different internal locking rings for different tires but i think they stoped doing that maybe the aftermarket picked it up i cant remember lol

I can already barely clamp them together, and once clamped, i have to pry them apart, with the bead and the bead lock/barrel having "bonded" (for the lack of better term, they stick together substantially). I indeed had to use even longer bolts than the included ones to get the bead seated/aligned.

While i can't be 100% certain, i'm reasonably sure that the bead on Tusks is actually thicker than that of at least Hyraxes.

I can't, of course, rule out that internally something isn't sitting right, but assembling them and seeing the outer bead, there's nothing slipping. That's, on the other hand, easy to figure out. Once home, i'll mark a line over tyre and rim, if the bead isn't clamping correctly then it's going to be immediately obvious.

I'll report back once i get that sorted.

im not sure im understanding what the problem is but let us know what you find

 

[m4inbrain]

No, it seems to be that i'm not understanding what you mean. If you say "it's not clamping on the bead", sounds to me like you're suggesting that the bead is slipping. That's the only result i can see from "not clamping on the bead", anyway.

And it's easy to test for that.

 

[m4inbrain]

Quick look - unless i misunderstand "slipping on the bead", which is always a possibility, at least on the outer bead that's guaranteed not happening.

Before.

After.

That tyre is vented and has drift foam around the inner ring to "squeeze" it in. The way i understand is slipping on the bead, is that the rubber rotates on top of the barrel (like, wheel moving, rubber not rotating, as an example). I can rule that out, the rubber is not moving independently from the barrel/lock, it's clamped tightly.
edit: i marked both outside and inside of the wheel, just didn't bother uploading it. The mark isn't moving on either side.

If that understanding is wrong, then, well.. someone would need to ELI5 it.

How many vents did you put in the tire and what size?

 

[m4inbrain]

How many vents did you put in the tire and what size?

Currently two, spaced 180 degrees, around 5ish mm diameter, centre of the tread.

So, thought of one more thing, this time it's pretty conclusive.

To explain, here's two pictures after a 30 yard drive.

That's the Squid'nsert, business as usual.

Here's the other front wheel, where i switched out the anti-foam with the standard stock cheap and nasty foam that came with the tyres.

Same drive.

The beads lock just fine, there's nothing slipping anywhere. I don't know why the Squid'nserts are doing what they're doing, but they're the reason for the tyre crumpling. SL3D of course isn't getting back to me either, and at this point i'm starting to get pretty annoyed - those inserts were almost $150 to me (after shipping, duty, taxes).

Time to look for an alternative, chalk this up as a learning experience and stay away from SL3D, for me.

That's unfortunate indeed. For Tusks, I have found the best luck with Crawler Innovations 4.75 foams. Comp Cut, soft in front and medium in back. I like squared foams for squared tires.

I used Halo foams in this review and they also did very well, but I favor the CI foams just a bit more.

So, 3d inserts are the problem and not the combo Seen that funky look many a times online with these type of inserts so confirmation is appreciated.

Thanks for the pointers, got to think about it a bit now - my fronts are now vented on the tread, and i'm in the UK, where 350 days a year it's, well.. raining. The other few days we drive at the beach, which isn't dry either.

So my options are to either get a decent dual stage foam and put a lid on the printed stuff, plus two new tyres - or find another set of anti-foams with a company willing to help out if their product is defective.

I'll likely stop the experiments and look into dual stage foams though, kinda cured from this rather expensive experiment. Certainly going to look into the CI foams, cheers for that mate.

I can't speak for any other person/problem, but in my case, yes - 100% the insert's the problem, the tyre and rim work perfectly fine together.

Yeah, that rain thing is no fun. Ottsix foams handle wet conditions fairly well from what I hear, but as you can imaging, we are not running in too much rain out here. We actually try to avoid the sandstone when it rains because hiking on them can damage the soft sandstone quickly. Wishing you some luck on this.

Cheers bud - read your article, i'll be going with CI 4.75 comp cuts, soft front and medium rear as you suggested, as well as a new set of Tusks for the front. Of course, they're also not available in the UK, but Amain charges $2.99 for shipping to the UK, as opposed to the $55 SL3D wants.

Amain usually also gets back to me if i have a question, as a bonus.

Here is a link of a video focusing small section of trail out in our area. The rock is known as Ahab and it's ruined many a crawlers day. We are running the Ruptures, which are a thin tire from the same company. Inside are the CI foams. If you watch the rear tires, you can see them take nearly the entire load of the truck and not twist around the wheel, save a few brief moments. Just a bit more data to support your ideas and direction.

And one more with Tusk tires. They can really perform, just gotta get the foams setup right. You're on the right path in my opinion.

 

[1fox2go]

If it helps. I have had good luck with the Deuces wild single stage foams for my tires that I know I will encounter water. mud, snow etc. They do not perform as well as a hardcore crawler setup but for a trail truck I have been very happy.

try dusting the inside of the tire so the tire dosent stick to the insert

That might be at least part of the issue - friction between the tire and the insert.

I have many, many wheel and tire combos but mainly because of the expense have only bought aftermarket inserts for about half a dozen.

No 3d printed or silicon inserts, only dual density from CI or Amazon.

My ONLY set of tires that does what you are experiencing is the 1.9" RC4WD steel spokers and Mickey Thompson MTZ Baja P3 tires that came RTR on my C2X.

I'm actually running them on my Element Enduro and they get twisted sidewalls quite often, but if I then punch the throttle in reverse for a few seconds the sidewalls go back to normal.

They aren't vented - I have thought of maybe putting some powder inside between the tire and the insert, just never got around to it yet.

 

[Col_Sanders]

My opinion as someone who is constantly screwing around with tires and inserts....

Add more vent holes. Two on the sidewall would be best, but two more in the tread area should work. That should allow the air to actually flow freely as the tire compresses and returns. 3d printed inserts have more air volume than foams and they do not allow it to flow as well unless there is adequate venting. These have 3 on the tread area and 2 on the sidewall.
