The hubs were wire wheeled clean and then painted in black hammerite. I hope it's only the paint you can see.
Is the paint an issue? The hubs were clean and mating parts flat after I wire wheeled them.

It does rather look as though your back plates may be stood on rust around the bearing boss, which could distort them as the bolts are tightened.
A wire wheel wouldn't clean it off, you need a small chisel and hammer to shift the scale.
Assuming that the hole through the back plate is the correct size, aftermarket and all that...

I used a hammer and screwdriver (as a chisel) before the wire wheel as I could see remnants of the old backing plate.
Anyone have experience with aftermarket backing plates not fitting the bearing boss 100%?
The wheels are turning pretty well now.

Thanks Aidan and Silverbullet, you were both right, I hadn't removed all of the old rusted backing plate. I could barely see it, but another go with the wire wheel and chisel/screwdriver and this bit fell off.
The new backing plate is sitting flush now and the wheel does spin a bit better, but not that much better. Maybe I need to do the rear wheel bearings too?
Cheers for the tips.
