Default E90 sedan appropriate offsets for wider rims - 09-10-2018, 08:48 AM

Am looking to go with 19 inch rims in order to get the Michelin Pilot PS4s. In front I'm moving from 8 inch to 8.5 inch, and in the rear from 8.5 inch to 9.5 inch widths.

In researching offsets, my current fronts are 34 and rears are 37; from what I've seen, it appears that in order to keep the tires in the same position relative to the outside fenders, the offsets would need to be increased by about 6 on the front and 12 in the rear; however, at least on the rear, putting the entire additional inch inside the fender well seems like it may be a stretch.

I haven't seen any information that shows the total space between the inside guts and outer fender to know what the total amount of space I have to work with is, and I'd prefer not to buy something that I think will fit, only to find that it doesn't.

That being said, anyone have experience with 19x8.5 ET40 fronts and 19x9.5 ET45 rears?

On 07-08 cars you have 8mm more to work with in the rear. Those offsets sound more like an LCI offset, I would get something more aggressive.

Well... I decided to go for 19x8.5 ET30s (with 235/35 PS4s) on the front and 19x9.5 ET35s (with 265/30 PS4s) on the rears.

The fronts are rubbing a little, but the rears are just fine. I kind of wish I knew how much inside clearance there was before making the switch - everyone's focused on rubbing the fenders, but I don't know how much room there is to work with before hitting the suspension...
