as the 17" rims just touched on the rim edge...just thought I was unlucky, but the 18" would actually clear the lug so no problem at all to fit the 18".

sorry now i'm a little confused?
17" need something ground down to fit?
18" go straight on?

Going on what Tango says the 18" rims clear the lug by virtue of their greater diameter,
(they actually go outside & around the lug)
The seventeens are smaller diameter and are tight enough to just catch the lug on the inner rim edge.
Hope that makes sense
