What are these white spots on my alloys? Is there anything I can do to prevent further markings? 

A feature of diamond cut alloys! 

Its water that has got under the lacquer, be that from a stone chip or peeling paint.  Over time it will just get worse.  You could try looking for any chip or peel and touch in with lacquer

My xtremes have similar. RIght now they still look good unless you really inspect them close. At some point in the future they'll get worse though.

 

My current plan is to wait until I can't bear it any longer, then get them powder coated black (no diamond cut).

 

An alternative option I'm considering: you can buy single wheels from a Skoda dealer via ebay, and about twice a year they do a 10% code off any purchase. 2 of my wheels are worse than the other two, so I'm tempted to buy two new diamond cut wheels when the offer is next on and swap them over. By the time I've sold the old ones it's not going to be that much more than a refurb and I can retain the diamond cut "look".

Unfortunately it's pretty common with diamond cut alloys. My extremes have the same issues. Has anyone ever had feedback from dealer concerning this?

Take your pick:

 

'Gosh, we've never seen anything like that before...'

'No sir, not warranty related, I'm afraid that's fair wear and tear...'

'You do realise that by modifying your alloy wheel, you've invalidated any warranty you may have had.... we advise you to inform your insurer that you have had your alloys wheels lightened...'

 

MD damaged two of my alloys when changing tyres.  Rejected my complaint as 'existing damage' until I showed them timed photo's from when I'd left the car with them two hours earlier.  It was apparently the machine that did it 

 

Gaz

I've got those spots on mine and they do my head in. 

 

I took the wheels off, thoroughly cleaned them and then polished and waxed them. I haven't seen them getting any worse. 

The curse of diamond cut alloys! Would a wet sand and re-lacquer work? That's what I'm planning on doing to spot treat mine if and when it happens

Cheers I think. Looks like we are cursed with a feature of the diamond cuts. Time to see the winter out and take stock next Spring. 

Mine are similar. My plan is that at first damage post-warranty expiry, I will get them all refinished in the grey colour without the diamond cut.

Loads of threads on the White Worm over the past decade in Briskoda forum.

Tyre fitters damage alloys. I kept mine pristine until I needed tyres after punctures. Different tyre fitters damaged the rims and a scratch along one of the spokes - sickening. I have not even curbed them after 7 years.

Tyre fitters may well damage rims.

But white worm on wheels that have never been to a 'Tyre Fitter' other than in a Skoda Factory, then transported and arriving at a dealership and getting no knocks is to do with the actual wheels as purchased by VW Group and fitted to the cars.

Crap idea where style has become more important than the longevity of the product which needing treated with kid gloves.

How can OEM’s get tyres on wheels with no damage? Is there something about the replacement process that leaves wheels susceptible to damage?

 

Or is it that we just don’t see the damaged wheels from the factory? Is there I giant pile of scuffed alloys out the back next to the staff car park 

You can watch how tyres go on rims in a factory on Youtube.

 

Tyre Fitters in a Tyre & Exhaust centre clamp the wheels differently.

Some are hashy and damage the wheels, or clamp not in the centre bore only.

Some are hashy just moving wheels / tyres from the car to the Tyre Fitting Machine, then the Wheel Balancer, and back to the car.
