I'm thinking about getting some 255/55/18 Nitto 420S tires for the back of my Mag and then eventually 235ish/60/18 Nittos for the front. I'm also thinking about a drop at some point. My question is if I'm planning on dropping the car (just a bit, nothing crazy since it's my daily driver) will the 255s give me rubbing problems? Should I just save my money on tires and put that away for the drop instead? Any other ideas?

A 255/55/18 tire will give you an overall diameter of 29". Assuming your on an 8" or 8.5" wheel with a recommended offset, (+18) you should be fine.
Your not a dumb ass. We all learn at some time. Here you go.....
The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel. The offset can be one of three types. (measured in millimeters)
Zero offset - The hub mounting surface is even with the centerline of the wheel
Positive offset - The hub mounting surface is toward the front or outside of the wheels centerline. The higher (more positive) the offset, the closer in toward the strut the wheel will mount.
Negative offset - The hub mounting surface is toward the back or inside of the wheels centerline. With negative offset, (lower) the wheel sticks out further.
Further explained:
Wheel offset numbers refer to the distance the mounting surface of the wheel is in mm from the centerline of the wheel.
If you looked at a cross section of a wheel. If the wheel mounting surface was on the wheel centerline, that wheel would have "0" offset. (On left in pic below)
If the mounting surface was pushed outside (+) the centerline, that would be positive offset. Note that the higher the offset, the further away from the wheel centerline goes the mounting surface. This positions the wheels edges in tighter. (center of pic below)
In a negative offset, the mounting surface would be positioned inside the wheels centerline (-). This would cause the wheel to sit further out. (on right of pic below)

Hope this helps you out. Any other questions....I'm here.

Fireman, how wide of a tire can one go with on the stock 18" wheel? I'm running 255/55 Nittos at this time. I'm coming up for a tire replacement soon and want to keep the stock wheels but go wider tread in the back. Is this a doable proposition? Thanks!
