This may be old but its my first day on here. I have a 14 hatch lowered on corksport and Im running 18x8.5 plus 35 offset on oem sized tires. At that offset and width I had to pull and roll my rears and a slight pull in front. I believe your 100% safe with a 18x8 or 18x8.5 as long as your offset...
Im same as above, Im on 18x8.5 with 215-45-18 but Im running a more aggressive offset at +35, I had to roll and pull the rear and a slight pull up front. Im also at the same height as see above.
