offset is the number in mm from the center of the wheel. so +35 is 35mm towards the outside of the wheel from the center of the wheel. the center of the wheel is 0. -35 is -35mm towards the inside of the wheel (towards the car). the lower the number, the fatter the lip.

The offset of a wheel is the distance from the mounting surface of the wheel to the
true centerline of the rim. A positive offset means the mounting surface of the wheel is positioned in front of the true centerline of the rim / tire assembly. This in effect brings the tire in to the fender well more. Conversely, a negative offset means the mounting surface of the wheel is behind the true centerline of the rim / tire assembly. This will cause the tire to stick out away from the vehicle.

Usually a range of offsets will work for a particular wheel size. The range is usually only 5 - 10 mm though. It really depends on the vehicle though as some have more clearance in the wheel well.
