Yukon wheels. Help.

You need to get the bulge lug nuts.

Would the stock lug nuts that came on the Yukon with the wheels work???

I'm pretty sure the Yukon studs have a different thread then the Mazdas. So the Yukon lugs are useless.

When I go down to my local tire shop what kind of lug nuts should I ask for?? I don't want to walk in to the place and sound totaly clueless.

You want a conical bulge seat lug nut with a 12mm x1.50 thread.
