Are these cracks around the spoke holes?
Had these Hunt 4Season Disc wheels for a couple of years, they've not done that many miles as they are just a winter set (one and a half winters). While cleaning them today I noticed some corrosion on the nipples of the rear wheel and what I thought look like cracks. I'm no expert but I just wondered if they were still OK to use? The front wheel is absolutely fine.

If they are in warranty - send back to Hunt. If they're not - into the recycling bin.
Assuming you are the original owner you ought have a shout at warranty replacement of the wheel? They offer a full 3 years to the original owner.
Certainly I'd have thought it'd be safe to ride them to the end of winter then get them warrantied.
Failing that a local wheelbuilder should be able to replace the rim for not a huge amount of money.
The pics do enlarge.
28 spokes on 25-30 mm deep rims weighing < 500 g seems to be the norm these days.
Ollie here from HUNT. Sorry to see this issue - from what I can see it looks like you do have some hairline cracks emerging from the spoke holes there. Absolutely no problem to get these replaced for you under warranty.
I see you mention you've sent in the images already, so I'll follow this up internally to ensure you're being looked after to our usual standards.
Happy Holidays
For a start, disc brakes mean that rather than wearing the rims out through brake abrasion (which a winter and a half of usage might well do) the rims are still going - so something else will give sooner or later.
Then there is the fashion for rims not to be eyeletted, or particularly double eyeletted - any sort of eyelets will make cracks somewhat less likely (or at the very least, harder to spot) but double eyelets in particular should do a better job spreading the spoke load across more of the rim - unfortunately it's near impossible to use them tubeless, and nowadays people expect their wheels to be tubeless so they're out.
Then there's the trend for wider rims- they don't want to make the rims heavier, so instead they make them thinner....and the increased dish of the 11 speed freehub standards... etc.
Conversely a set of Dt Swiss rr585 rims without washers did not have this problem.
Remains to be seen how I get on with the current dt rr511 rim which mandates the use of washers (and comes with them supplied).
