couple wheel questions

[jESse]

looking to finally order me a set of wheels. just wanted to double check a few things before i do. our bolt pattern is 6x5.5 correct? and a -12 offset on a 18x9 will be ok too? the other choice is an 18 for offset. i'm going to be putting a 305/60 on em and keys/spacers if nessesary

305/60 is gonna be way too big. 305/55 +18 offset with keys will better suit you. Edit thought u were talking about 20s. 305/60 should be fine

i really don't think tire size is going to be a problem. this guy is running 325/60/18's on keys and spacers.

what i'll have is a 32.4" x 12" tire vs his 33.35 x 12.79 tire

you'll definitely need spacers, and if you go with that -18 offset you might even need a 4" lift. The tire size isnt the problem, its the offset.

its gonna stick your wheels out of the body, thats gonna make your tire hit your bumper and inner fenders when you turn.

I find it hard to believe that, the guy from the link posted above, didnt have rub issues with an 18x10 with a -25 offset on keys only? (if i got his info correctly)

I am looking into replacing my 20s with a diff style rim. Both of the wheels Im looking at are 20x9 with offsets available of +12, 0, -12. Which equates to 5.5", 5", 4.5" of backspacing if my math is right. I know I will not go with -12 cus I dont want to rub or have enough lift. Currently running 275/60R20 (33x11x20) and I only scrub a lil bit in full turn on a decent incline. Fender height is 40" on all corners. What offset would be best for my application +12 (5.5) or 0 (5)?
