I decided to replace both wheels. The wheel rear was in bad shape. I was able to restore the bearings and freewheel, but the spokes were noodles, 2 were broken and several nipples seized. Front wheel is doable.
I found a great package deal on Amzn. Both wheels, freewheel, tires, tubes, rim tape for 60 euro. So complete replacement was a matter of economics. A rear wheel, freewheel, tires, tubes and tape would have cost the same.

Keeping with making the bike unattractive to thieves, does anyone have any suggestions how to make the new rims and tires look old?
