Will these work with my current wheel studs?

M12 X 1.5 is a common metric size. Verify your vehicle's stud thread pitch matches this spec before ordering — if you're unsure, check your owner's manual or measure against your existing lug nuts.

Do I need to prep the wheel seat before installing these?

Clean the wheel mounting surface and studs of any corrosion or debris for proper seating. Wipe down with a dry cloth, then hand-thread each nut and tighten in a star pattern using a torque wrench set to your vehicle's specification.

Can aluminum lug nuts handle street use?

Yes. Aluminum is strong enough for daily driving when properly torqued. The grooved shank prevents loosening and the closed end design protects studs from corrosion — just make sure you use the correct torque value for your specific vehicle and wheels.
