Sorry lol. The place I got them in the past I canāt find anymore. I just look up 9x3.5-4 tire and they pop up. I would try for CST. Airloc and Carlisle are good but not as balanced in my experience. Lmk if you find a good site for em.

Itās not the bearing spacing that matters; itās the distance between the lips, which is 42.7 mm on Fivestars and 54 mm on Pro XLs. From my experience 8x3.00-4 fits well on XLs, and you can get them to fit, but theyāre narrower than ideal on Fivestars. AFAIK, for 9x3.50-4, you need spacers even on XLs.
Iāve got a model for 20 mm Fivestar spacers like 95% done, but I gave up on it. Iām using Matrix IIIs, so my plan was to use those on the 70 mm axles because they would extend the bearings 20 mm, but I was running 8x3.00-4s anyway, and decided I didnāt think it would actually affect the contact patch enough to bother once I aired them down. I was going to do some tests on Fiverstars vs XLs to see if there was a noticeable difference once aired down and having weight on the board, but never got around to doing it in a way that showed much.
Anyway, I wouldnāt expect 9x3.50s to work on Fivestars. Also, mounting 8x3.00s has been a pain for me. They like to get stuck half on the smaller lip and half on the larger lip on both Fiverstars and XLs for me. If anyone has advice on preventing or fixing that, Iād love to hear it.

Use some sort of tire lube when installing them? Or soapy water.
I tried that before, and it didnāt really seem to help. I think Iāve got it down now, though. The trick, for me at least, seems to be to put just enough air in the tube that it puts some pressure on the sidewall while installing it. That pushes the tireās lip over the inner lip on the MBS wheels instead of letting it fold under.
Idk if it is even an issue on other wheels. Do other wheels do the MBS thing where they have two lips, one for 94 mm and one for 100 mm?
Yeah, if you put enough pressure the tire will eventually fits. Just make sure those tire beads is correct size for what youāre using.
No, most hubs only have one beads. You just happened to have the two hubs in the market that has two lips. 
Iāve got some other wheels, but theyāre all only for smaller tires with a 94 mm opening. Also, I already tried just overinflating them to try to get the bead to move, but it seems like they need some pressure while screwing the wheels together. Iām not really willing to go over 80 psi even with the tires not moving, and that wasnāt enough to move the bead once everything is already together.
Whatās the deal? Did the arm break or the pot? Glad you got a ride though. @Egtscs had the lever arm in his break but it was usable to get to a repair spot then we printed up some spares incase it happens again. Hmu if you need files or something

This the remote recommended alongside the puck 2.0? Trigger remotes get a different set of standards I guess.

Fighting words 
To be fairā¦ I have the split trigger and it doesnāt look like this on the inside
For what itās worth, this lever design was changed almost 2 years ago and changed again more recently, additionally this isnāt a failure mode I would consider dangerous. When the lever breaks your trigger is still attached to the hall sensor and will continue to function for throttle and brakes without the return to center.

Good points lol I just felt like being a lil feisty today 
slow day at work
There is value in a tried and true design. That value outweighs the value of my preferred throttle type. I would not compromise on this for my own safety. If I were to apply points to each spec of an esk8 remote Iād put 10x more weight on mechanical/electrical reliability than throttle type.
So if someone doesnāt have a preference then Iād recommend the most reliable remote with the most testing. This isnāt what I see happening.

So I suppose if someone made a car with tried and true control design, but the gas and brake pedals were on opposite sides than usual, youād prefer the tried and true over staying with the design you have muscle memory for? Because thatās what you are indicating would be not compromising for your own safety. Iād argue it would make you far more unsafe, because the problem you are solving is at the expense of another problem.
There is also high value in staying with the control that you have muscle memory for, because in a sudden unexpected situation, your reflex knows which control to operate. A reflex is a quick, involuntary response processed at the spinal cord level, with no regard for higher-thinking. And using the same control type you are accustomed to is crucial for reflexes to keep you safe.
I was running the 9x3.5 cst c190 for a long time and thereās a couple things to know - 1, they last forever. My first set is still being used, although recently it seems like either I got used to even more grippy tires (definitely true) or they are starting to loose some of their grip (I suspect also true). 2, you are best off with the mbs xl hubs and 3d printed spacers. Ping me so I wonāt forget tomorrow and Iām happy to send some 3d printing files. Extended mbs XL hubs still use regular 38.2 bearing spacing
Flaw in this analogy.
Thumb wheels are the most popular by far, so they would be considered the gas on the right brakes on the left.
Triggers are the cars with the flipped controls in this analogy. Nothing wrong with them but they have a lot less proving them than the original. Someone getting into driving a car for the first time should probably go with the more popular and common and tried and true method. At least until those flipped controls cars have all their issues ironed out.
For example, the pairing process on the Zmote reminds me of the type of thing youād do on an RC car and requires taking things apart. Makes carrying a spare remote less practical

The new Zmote pairing does not require opening the enclosure. You claimed there was a flaw in the analogy, but you did not show any flaw. I didnāt claim one way was better. I am simply saying that switching can be dangerous. You clearly also seem to have an agenda youāre pushing.
