Was changing a wheel out due to a nail (actually a wheel stud with blunt end!) penetrating one of my tires on a recent trip and noticed when done I could "wiggle" most the lug nuts a little by hand after torquing them which seemed really strange. Never looked into lug nuts before and found they are two piece lug nuts (WTH). Apparently the "decorative cap" just wears over time and with impact use and can even swell/deform so that standard sized sockets no longer fit on them. I could still torque them on fine but still swapped out a few good ones with other wheels just to ensure nothing else going on to get me home 500 miles. My wheels have only been removed a few times so they did not hold up well and will just get worse. I do use an impact for removal and only to loosely get them back on once started by hand as have the proper torque wrenches for torquing.
So, my next upgrade is lug nuts of all things
. I went with McGard model 64010 as they are a highly trusted brand from my research with lifetime warranty and one piece. Their are some doing full stainless steel one piece lugs which would probably be the next step up but can get really pricey and suspect some risk of galling/damaging wheel studs but not really sure, so stuck with McGard's. Also, most the stainless ones are "standard/cone" style where the socket would make contact with the wheel surface whereas best to use "bulge" style lugs that prevent the socket from making contact with a nice aluminum wheel so does not scratch them up. There are some much cheaper china one piece lugs out there that are probably just fine and way better then these two piece likely china china ones they gave us but not worth the risk to me. Make sure the lugs are truly a one piece as some are even mentioned as "lifetime stainless" but are still two piece and just the cap is stainless. You can see a visible line between the two pieces if look closely on the two piece lugs.
Not sure if later models rigs might have gone back to one piece lugs, but apparently most new autos still have these junk two piece for some reason too.
