I've tried wiping the surface of the wheel using a cotton bud dipped in MEK- seems to have no effect. I then tried immersing the wheel for a few minutes - that made the thinner part of the rubber towards the centre of the wheel becoming "rippled". That effect went away overnight. The edge of the wheel is still hard though.

I also tried brake fluid to no effect.
