does it matter if the ends are tapered????

The taper helps to center the stud (not wheel). Probably not a huge deal when you have 4 other lugs already doing this, but it would have been better to get the ones from courtesy nissan.

I disagree. The taper makes zero contact with the wheel -- you can see this if you just take off one of your stock lugs and look closely at where the marks/scratches are. The taper is completely irrelevant. What centers the wheel is the hub, not the lug nuts. Hence the term 'hub-centric', as in hub-centric wheel spacers, for example. Think about it. Mount your wheel, but before putting any lug nuts on, if you move the wheel side to side, do the walls of the holes bang into the studs? No, they don't, because they're already centered.

I do agree that it's better to get the ones from Courtesy, now that they're finally available (I got my McGards before the 'real' ones were available). If you've already got the McGards, however, I see no reason to waste your money on ordering another set from Courtesy. I've had mine on for 4 months now without any problem whatsoever.

There are two sized holes in the wheel for each stud and the taper can touch the smaller of these holes, although with the washer style nuts it will probably never touch as the washer will make contact with the flat area first. Even with hub-centric wheels there can be a small amount of rotational play on the studs, on ours it is extremely minimal if non-existent. Hub-centric means that the wheel self centers over the hub (i.e. tight fitting hub) rather than being centered by the lugs. I wasn't suggesting that this was a lug-centered setup but rather that the taper could help to center the hole opening on the stud to stop it from crushing the threads with rotational movement. The McGards at least are the correct length and have the washer area so they are 10x better than what most of us received on our car.

Ah, gotcha. Thanks for clarifying.

I re-read my original post and I did definitely mis-speak, (mis-type?). It was late and I was tired

Sorry for getting you wound up and thanks for the edit

and thank you for the reassurance
