I'm think about going with 285/55/20 on a +18 offset rim and I was wondering what kinda trimming I will have to do if any. I will have the Cognitio leveling kit installed. If anyone has any pics of this setup please post.

275/55-20. Rims were not as offset out as I wanted. Worked an didn't rub bad. I turned keys up a tad and they were fine. Stock suspension. If I did 20s now I would go 285/60 since I am getting my cognito leveling kit next week. Pumped. Going 285/65-18

Here are the rims i just got. +18 offset KMC spys with 305/50 20 Cooper Zeon LTZ's. They measure out to 32" so about an inch shorter than 285/55s. Apologize for big pics.

That is the same set up i'm looking at getting. Did you have to trim at all? I wonder if they make the Spy's in a 9 or 10 wide rim?

I got the 8.5" wide spy. They come in 8.5 and 9. I think the 9" wide rim is when you go with the negative offset for lifted trucks. I may be wrong about this but think that's the breakdown. I haven't trimmed anything. They only rub when stuffed and in a full turn. But i do have a leveling kit but it's still sitting nose down. T-bars aren't cranked all the way up.

I'm looking to go with these same size BFGs on 20s, I've got the Readylift leveling kit installed and I'm prepared to do some slight trimming. What offset are those wheels?
