I have a local guy with a decent deal on a set of liquid metal magma wheels. I wasn't really in the market so I haven't done any research on what will fit, tire sizes, etc. so I have two questions

1.) Do they require special lugs?

2.) What size tire can I install without a lift?

My truck is an '11 FX4.

1.) Yes, they will require some thinner acorn lugs most likely. Bring them to your local tire dealer and they will be able to tell you exactly what lugs you need.

2.) That depends on what size they are. Give me the dimensions and I'll give you some suggestions. Diameter, Width, Offset/Backspacing.

Also ensure that these wheels are meant for your truck, they need to be a 6x135 bolt pattern.
