To measure the offset of the wheels - lay the wheel face up on flat ground. Measure from ground to the hub mounting face (call this A), then flip over and do the same (call this B, make sure this is still to the same mounting face). Add A and B together and divide in half (call this C). The difference between C and A is your offset. If A is bigger than C its positive, C bigger than A is neative offset. Having tyres on makes no difference to the measurements as they wil bulge the same on both sides.

Most older RWD's are around 20-25P, FWD is generally 35P or more. More positive offset than factory and the wheels are likely to hit your struts. Less positive or even negaive offset usually gives guard clearance problems.

Is that a piss take? A+B= the width of your wheel. You are measuring from either side to the same point.

The second part, minusing C from A is right, but to get C you just use half the width of your wheel, right?

yea but try measureing to the centre of your wheel....

I think offset+width is the way to tell if the rim will fit or not

but it's always very hard to meassure offset with tires on,so back space and the distance from mounting surface to outter rim is the way tell where the rim sits exactly when on car.
