Beware of idiots
use a gorilla 13/16 socket and you will have zero issues. Once you mar them, you might as well go out and buy new ones because they will look horrible after the fact.

Good catch, yes it's .36mm difference between 13/16 and 21mm. Had a brain fart with the decimal point after rounding up. And only use a 6-point socket since the lug nuts are 6-point, just makes sense.Not sure where the $100+ comment came from. CJPP has them for $60 and free shipping.

For the OP's original question - my opinion is to go ahead and change them before you have an issue. Granted, I tend to take my wheels on/off a lot, but I started seeing deformation fairly early. This does not echo the experience I had with the OEM lugs on my Focus ST which have been fine. I suspect the much higher torque doesn't help. I do not use power tools - hand tools only.
21mm and 13/16 are very close. At least for my particular socket set, the 13/16 fits a little better than the 21mm but both are looser fit than I would like. Either would do in a pinch. YMMV, sockets tend to have a lot of variance among manufacturers for some strange reason.
I know we're expecting to find all metric fasteners on a late-model car but I'm pretty sure this one is SAE on the lug nuts. Not sure where the guy above got 4mm difference between 13/16 and 21mm. It's 0.36mm. If you have nicer sockets with the reliefs cut in the corners it's close enough.
EDIT to add: I wouldn't use a 12pt socket on a lugnut, regardless of how many pieces it's made out of.
Like many of us, Iāve turned wrenches my whole life, both as a profession and at home. And my best friend works for Mercedes Benz; has since high school. He would tell you thereās no reason what-so-ever to even own 12 point sockets unless itās for a 12 point nut! And thatās not just for lug nuts, but for anything.And only use a 6-point socket since the lug nuts are 6-point, just makes sense.
I think the gorilla brand would be fine on track. Just make sure they torque to spec! ... your getting way ahead of me Andy.. I'm going to have to catch up! LOL>..https://www.cjponyparts.com/gorilla...style-bulge-black-chrome-2015-2020/p/WHLLN20/
nevermind found it.
These are cool on track as well?
Honeybadger said to run these so I ordered a set. They should go nicely with the new Cup2I think the gorilla brand would be fine on track. Just make sure they torque to spec! ... your getting way ahead of me Andy.. I'm going to have to catch up! LOL>..
