All I said was you'd need something less than 8" wide to fit without any modification or effort. Plenty of people do it and I'm glad you wanna try . It's just a matter of doing the math, and as krip said the wheel offset is a very important part of that equation.

 

i run 8 inch with 235 fine in the back and raped my fenders in the front now they are all bent out

 

Ok the guy with the bbs said he has half inch bbs spacers hell sell with them. I clearly dont know anything about rims or spacers. Does this help with offset issues or do i need to like calculate the right size spacer once he tells me the offset?

 

Bump. Apparently he doesnt get home til friday and cant tell me offset til then. But how do u calculate size spacer needed?

 

Both the width of the spacers and the offset are typically measured in mm. Once he tells you what the offset of the wheels is, you can work out how thick of a spacer you need to make the final effective offset livable. For the record, 1/2" is about 13mm. So if the offset of the wheels is et30, add the 13mm from your spacers for a final offset of 43mm. (just an example)

 

Those are RS6 reps. I have OEM RS6 wheels, they're not far off.

 

I had the same issue, I went to a 235-35 from a 235-40, which helped a lot, I also rolled my fenders.

 

i have 235/45 i just got new 235/40
would 235/35 ruin the diameter and blow the center diff since its smaller?

 

So when ur adding offset+spacer = x mm. But how many mm do i want total for the rim with these specs : http://boston.craigslist.org/gbs/pts/3005497490.html. Im aware i need offset for the equation but what do i need total to run these wheels without rubbing or bending?
