Will aluminum lug nuts work with my current wheel studs?

Yes — these are M12 x 1.5 threaded and will screw directly onto any vehicle stud with that specification. No modification needed.

Do I need any tools beyond a lug wrench to install these?

Standard lug wrench or socket wrench is all you need. Installation is identical to replacing factory lug nuts — hand-tight first, then torque to your vehicle's specification (refer to your owner's manual for the exact value).

Can aluminum lug nuts handle street driving or should they only be used for show?

Aluminum can work for street use, but understand it's softer than steel and more prone to stripping if over-torqued or cross-threaded. Use care during installation and tightening. Check them periodically after mounting new wheels.
