Flatten the tread, till almost flat. Maybe angled with camber, so it only flattens with turn. Add antiflat band. research the rubber used in Shwalbe bike tires. If they last long, and dont pop, you could charge more, way more. People would pay to not have problems.
OK, this is the direction I am headed.
- The BRP wheels are a stand alone project that I will attempt to adapt to a wider audience. They are strong, lightweight and can be easily cut to the desired width. In addition, I do not have to use an excessive amount of our compound to make a 5" (125mm) or 6" (150mm) diameter wheel that can be up to 3.17". (80.5 mm wide).
- If our compound is viable and exhibits desirable characteristics on the BRP hub, we will make a version to fit existing two part pneumatic hubs such as the Stooge Race Board Widening kit, plus stock Trampa, MBS, Kaly, Metro and Evolve. We are addressing the expansion at speed issue from the beginning so expect our tires to be dimensionally stable.
- We have a 2 part spun aluminum hub in the works that we will use to make a high performance race wheel that will be available in different widths. The emphasis will be on racing go kart tracks, hill climbs and A to B road racing.
Stay tuned, we have lot of things in the works!

Very interesting, I’d like to see side-by-side spin up tests with this compound vs TB110 and other thane or airless wheels and pneumatic maybe.
I would really like some high speed wheels around this size for track runs. Weight low!

Here is a cutaway of the BRP Core
Weight is 800gm for the full dimension wheel with a massive aluminum hub complete with 30mm bearings installed. Our compound accounts for about 500 of the 800 grams.
RipTide Barrel for perspective.

This ^, if you could make a 85-90mm version you’d have a crowd of DH, street and DIY peepz that would be able to mount em and get in on the grip game

Bruh, I use 130mm wheels top-mounted on short decks. You’re just not trying hard enough

I can look into this but likely in a harder durometer. The over molded wheels in the pictures above are 60a

How do you adhere tire to the aluminum core?
Or do you not, and hope there’s no slippage at high torque?
I understand and I have a mold to do that but the compound will not be bonded to the hubs, I have some aluminum hub halves that will be suitable to test for DH applications but not powered setups.
I am not currently using an aluminum core, the compound is bonded to a Nylon 6 core.

Sounds awesome, hit me up if you need a EU testpilot

If this is a proprietary thing, ignore me, but what adhesive type works well for composite to nylon 6 bonding?
I had a work project in a past life bonding natural rubber to aluminum wheels, and it was seriously black magic stuff to get it to bond with any longevity.
80mm wide. Ohh yes.

Bonding is half the secret of this project I am afraid.

OK, here are some traction test conducted over the weekend, we have more work to do!
Everyone agreed the material is better than urethane but still not where I want it to be. Use the rotate tab to orient the video

Would you be able to test the compound for inline skate style wheel if you have a mold & core for it?
I’d love to compare the grip on the edge with some race wheels! Dual density stuff like Bont or RollX.
Also how was the slide at grip loss on your tests? Is it regular “lose it all” “catch all back” behavior or more progressive than regular PU?
Super stoked to see progress on this!

The dynamics are different for Inline wheels, you might want to read this: Grip-Vs-Lean.pdf (861 KB)

Thank you for the good read, from first lecture I understand that per se I should have more progressive grip to slide transitions on inline wheels than on regular flat patch wheel just by overloading the grip while in lean ?
If this theory applies, this compound would be even more interesting and even for non motorized regular racing or marathon rollerblades you might find a big customer base, starting by me
