I have been looking on line and have found a couple sites that explain how to to measure wheel offset. I have not yet had the chance to check my 55CV. I was wondering if anyone (I'm sure most of you already know this) knows what the widest wheel/tire package I can fit inside my stock wheel wells? I will be be checking this myself, but would like to know that I've done it correctly. Thanks for any help/info on this,
Rowen

By the way, I should mention that I'm looking for the rear offset without skirts..thanks again,

They make a tool to do that, but it's easy enough to build your own. Someone posted his version here I think, some time ago.

That said, when I went to 7x15 rims on the bird, I did my own measurements. Then a friend with a 57 bird (and the same salt flats wheel) told me the local Les Schwab would be about the same price for the wheels, and would guarantee the fit. So, I went over and talked to them, and they confirmed it. They did a bunch of measuring, and came up with the same backspacing I did. 3 1/2" front, 4" rear, IIRC.
I told them I was ordering Diamond Back tires, no problem, just bring them over.
They fit wheels (they needed a little ground relief to clear the front disc), mounted the tires for the standard charge, replaced a front stud, no charge, and sent me on my way. With 225/60's in front, and 235/60's in back, it's real tight. On a hard left turn, I got a little rubbing in back. Turned out the body was 1/2" off center. Centered the body, and all is well. Until he sent me over, I would have never thought of using a chain tire store, but it worked out pretty well.
Hopefully, someone with a CV will chime in with more measurements.

Hi Rowen
All you need is a metal coat hanger with one end looped so that a wheel nut can secure
it to the drum. Then, bend it to the length that approximates the tire at it's widest point inside
toward the body. Write that measurement down, then do it to the out board side and record that
measurement. Those measurements will both give the offset needed and max tire diameter.
OR, you can do it with (2) rulers or straight edges in the same manner, using a C clamp to hold
the two together, but it's a bit harder.
That's how I did my 32, and it worked out well.
