Smaller Lugnuts?
 

Hey guys, I went in for an oil change and was told my lugnuts are swollen. They wanted $8 a piece so I got a set off eBay. I'm concerned though because while these fit (9/16") they are overall smaller than the OEM lugs.

Is my concern justified?

It doesn't matter what wrench size is required for your lugnuts. What matters is that the thread diameter and pitch matches the studs exactly and that ALL your lugnuts require the same wrench size AND that you carry that size wrench in the car. You don't want to be stuck on the side of the road with a flat that you can't change because your wrench won't fit a lugnut.
