Full Version: Question About Maximum Rim Size...

I'm wanting to get a set of summer rims for my Focus but am curious to find out the max size I can go with for my model and if 4/100, 4/105 or 4/108 is compatible with it.

Thanks!

4 x 108 is the bolt pattern (something of a limiting factor in terms of wheel selection) 17s fit comfortably with 215 40 or 45 rubber ... a number of guys on here have 18s but the aspect ratio is pretty low - not sure what it is but not a lot of rubber there to protect from pot holes.
I've seen 20's on a focus out here in BC. They were on like 35 series rubber bands.
SVT Dean put 19"s on his fucus.. ask him how he managed
You'll need to roll the fenders well or better yet (and much more cost), move to a widebody Focus RS kit. Those kits allow an 18" wheel set to fit without further modifications.
I had to roll my fenders with 17's to prevent rubbing when running 45 profile. With 40 profile I had no issues but you sure felt those bumps a lot more.
