interested to see how this works out for you guys…

oh… you’re stretching 200mm dia tires… never mind the below text:

I’ve never been successful in stretching a 155mm-160mm x 50mm to 75mm… I’ve blown out a few tubes and the tire sidewalls are too stiff, and not designed to go that wide…

sorry @Nacho, I didn’t give you aqwik response, but I had some shit I had to deal with today

about the most, width (hub wise) using existing tires is in the 50-55mm hub width. science has shown that stretching the hub width 15-18mm is about as wide as you can go…

the kaly helcats are a nice option but too wide for low profile tires… @75mm (guessing I don’t have them yet)I was excited when ernesto mentioned he was making these, but then science and experimentation happened… I’m still waiting for my hellcat hubs to see what can be done… but I honestly don’t have a good feeling…

as an aside, I know a guy in the kenda racing division, and I’ve talked with him about a 145-150mm dia. x 50-75mm width tire, but I’m afraid presently there is just not enough interest or demand…

if we were to get a 100 guys to buy a set of 5, that’s only 500 tires, and yeah there are future buyers for replacements, but the market just isn’t big enough to go into production… maybe in the future.

timo had a local mfr. create his haggy tires (inova or something, memory escapes me) maybe if there was enough interest a smaller mfr. could be persuaded to take up the task. But we’re still really a niche consumer.

so Nacho… you can see where this is currently at, and why I didn’t answer with a quick answer.

EDIT:

I’m not really stoked on the TB AT tires stretched… the hard chine in the sidewall tends to lead to crack following and the like… I’m presently using the TB AT rites at design width…

change of plans

I would like to do this group buy splitted on USA and EU. I managed to make a deal with factory so they would ship part of order to me in EU and another part to someone in USA. What does it mean for us? For us in EU, price of a set will be slightly higher, because we split shipping price on 250 (or so) tires and not on 500.
For USA people it will be cheaper because they won’t have to pay EU import taxes.

Is there anyone interested in taking USA group buy part? @Brently?

I’ll probably add those too since we have free spots for more tire models

@kook what’s all this chatter about–are you talking about putting a skinneier than 200 X 75mm tire on the hellcats? Sorry I’m confused what this is about why aren’t people just putting 200X75mm tires on these hubs

Yes I’d like the off-road ones

Edit. Actually they are 200x50? Nah I am after that 75mm width, is there an off-road 200x75 option? Would take a couple of sets if yes.

Also want the 9” off-road tyres that are same as MBS T2, Q-128.

And the 200x75 phatty type Q-122

So I guess 4 sets of tyres if off-road 200x75 is possible

Messaged factory rep if they could combine 200x75 with different pattern, but I think it won’t be possible, at least not for such a small order quantity like we are asking.

We need an elegant CADster like @ducktaperules @Pedrodemio @kook @moon etc to pull an MBS hub and design a spacer to remove the width bulge from the200x75 phatty, especially on rockstar II …Maybe this is old news?

Since they are just under compression a lightweight version for fancy printing like so

And a thicker version for saaay CF infused PETG or Graphite which anybody can get down with

I have a pair of Rockstars 2 on hand

A bit trickier since the printed part will also have to house the bearing, unless we increase the center distance from one bearing to another

For Trampa trucks It’s doable

Probably my ignorance, but the 2 bearings are housed in the original hubs sides? Leaving just a need for a longer spacer and bolts?

I’m elderly and confused

Exactly, this way we don’t put much load on the printed parts, with the Trampa Superstars, since the spikes are removable we can keep the spoke placement and just move the rim outwards

I sold my superstars with regular 8” tyres before these fat 8” tired became known. I could rectify that, but like yourself I’ve a set of MBS rockstars gathering dust. Ah actually they are the original Rockstars…never mind.

Platform-wise I can see these being killer on a Trampa shortboard if the build was light enough it may work on not completely hard sand.

Hey guys I don’t want to be a pessimist here but after a quick calculation we are at about 33% of the MOQ. In the past we have seen that groupbuys are mostly completed in the first few days because everybody is really active on the forum. So the guys who wanted to get in already would’ve.
I think trying to get the MOQ down is something we should look for instead of trying to add more tyres. Would like to hear your views on this :slight_smile:

We’ll that’s like being a pet shop that only sells cats. You are loosing all the dog buyers. Do a 30/70 and you’ll sell more.

Some might not be voting because they don’t want those specific tires but if Tin can add more tires without bringing up the MOQ I think we will have a higher chance of reaching it

I can agree on this part.

But not really on this part.

I do agree that giving more choices is attracting more people. But what I am trying to point out is that narrowing down the choices might help this case. In trying to lower the MOQ. Like an MOQ of 250 is quite doable I dont think 500 is.
Since we have such a high MOQ even with more tire choices I don’t think we will hit the MOQ. Atm we have 33% of the goal (not including the non voters) so counting in the extra guys willing to get into the group buy by widening the tire choice could maybe double this number to 66%. This still wouldn’t get us anywhere. That’s what I am trying to point out :slight_smile:.
Instead, halving the MOQ to 250 with 3 tire choices. Could get us to the MOQ needed since then we are already at 66% not counting the possible extra people joining in. Then some of us could consider doubling their order to get to the MOQ. Which only half of us need to do if no-one new joins in (again not considering new people join in). See what I mean?

Its hard to explain this via text hahah if you don’t get it I will just write it down. Also considering I am a non native I sometimes struggle finding the right words :sweat_smile:
