The tire glue didn't work. It might have been because the metal was too smooth (it really wasn't that smooth...), or wasn't properly prepared. But for whatever reason, as soon as I took the hose clamps off, I got to watch the polyurethane slowly peel back from the edges. Damn.

Apparently, urethane strip's natural position when wrapped around something is warped:
1. Try prepping the surface better and re-glue.
2. Try thinner polyurethane strips.
3. Cast tires (so the warping problem goes away)
4. Cast tires with attachment mechanisms embedded in them (solves both warping and mounting problems)
5. Find a wheel to bore out and glue on (so I don't have to cast tires)
6. Screw on the polyurethane strip (see below).
I seriously doubt 1 and 2 will work judging by how poor the bond was this time. 3 and 4 require expensive casting equipment (hey, R&D is expensive...). That leaves options 5 and 6.
Let's start with option 6.
Unfortunately, having the 8 plates waterjetted would cost me $120...ouch...again, R&D is expensive. Let's try to find something cheaper- on to option 5!
Now, it just so happens that I made the OD of the hubmotors 3.25"...which happens to be exactly the maximum ID you can bore out 125mm scooter wheels to. Check it out:
