Hey those wheels do look great. Tire size?
Best to use a torque wrench when tightening the lug nuts.

Too tight can strip the nut!

Too loose can allow the nuts to loosen and will fatigue the studs.

Its all about proper preload of the studs to minimize stress reversals which unchecked reduce the fatigue life which equals broken studs!

Nothing more embarassing than watching your tire / wheel pass you by on the expressway.
