I did my search and found this thread.
I am running Stock 2000 Limited 16X7 with 19mm offset and 1.5"/38mm spacers. That's 19+(-38)= -19 offset. I was running 265/75’s. I went wider as I went taller with a big 2" lift ". I did air-down a few times, out wheeling mildly, so liked the old style wheels and rims. I am still camping and playing but not wheeling or wheeling even moderately to get to a campsite. I lowered it one inch, am running 255/70's and may take it back to stock height to handle a bit better with these lower profile tires on 18’s. I want a little bit smaller diameter tire and less rolling resistance with larger diameter 18" rims, race truck, ha. I won’t give-up all the sidewall and for reasons of breaking rims. I see some very nice incomplete sets of three, not four 20’s and 22’s around here.
My Calc's
I found some 2010 Ford Edge Limited Rims cheap. They are 18X8 50 offset. A +50 offset-38mm spacer = +12 offset. The existing set-up has the tires about 1/2" outside of the fender flairs, so I think it will be close on how these 18’s fit.
My Experience
My wife is out of town and I found her wheels to be the same specsas what I am looking ot buy!!!
Blingety Chrome! Yah, I got them on my rig and I did a bit of swerving today and hard cornering. I had to test them out, before and after fitment of her 18’s with 245/60's. I want 255/50's which would be 1" less in diameter. What I found toady is that the handling is better. It’s a bit tighter with the smaller sidewalls. I also notice braking a bit for a little downhill that I normally do not = less rolling resistance. I got pics below and think they are too far in? Pics:
These look to be in nice shape, picking them up tomorrow:
