I'm running 25mm spacers with +42 offset rims (17"x7") and wheels/tyres fill the guards nicley. I would guess roughly +35 offset with your spacers would work.

Yes.

I guess I'll take the damn time to contribute since he has such a great title.

Hold on let me type.

1.25" is 31.75mm. So if you wanted the stock width wheels to be in the same place as your old wheels the offset needs to be 31.75mm less than the old wheels.



Gotta go. Explain more tomorrow.

Just keep the same offset and get a widebody. Less confusing.

Running 1 1/4", you can run 7" wide in a +35 to +40. I am running Konig 17"x7" on mine with 205/40R17s up front, and 215/40R17s out back. This is the company I purchased mine from.
