There's an easy fix for this, however, once you manage to get the tire onto the rim---overinflation!
I took it out for a 20 km ride today. The wobble is more noticeable on the workstand than on the ride, although it is noticeable. The tires are rated for 55 psi, so I did as you suggested and inflated to 80 psi. Nothing has popped into place as yet. Is the extra 25 psi enough or should I overinflate even more?
