Aftermarket wheel Thread.
Some tires run wider then others so a 265 Michelin PS2 will be as wide has a 275 Hankook for example.
What kind of tires are you planing on getting?
Does anyone here run the size combo that I mentioned before by any chance?
Plus it mostly depends on your tire setup.
With your current offsets 235/35/19 front and 265/30/19 rear would work fine.

The original ET51 offset had the rim flush with the fender and looked terrific, unfortunately the 285’s only just touched but touched enough to rubbed constantly. So much so I couldn’t drive it. I could have fitted 275’s as they would have been perfect but I didn’t want 275’s.
I decided the easiest option to stop the rubbing issue was to bring the rim inwards. After a lot of trial fitting, measuring and re-measuring to ensure the inner part of the rim wouldn’t foul anything if it was brought inwards, the rims were taken to a rim manufacturer. Before they were prepared to do any work on them, they checked to ensure they could remove material without compromising the integrity of the rim, they found there was plenty of meat where the bolts seated. They then turned them in their own lathe. One thing they did say about the HRE’s was that they were very well built and had a lot of scope for modification. They were very impressed by them and said the finish was great and I have to agree.
All they needed to remove from the base plate was 5mm (0.19 of an inch) and this allowed clearance for the 285’s. That’s not much at all. It’s now lowered and I can have 4 people in the car without any rubbing what so ever. As far as I’m concerned it was worth what I would consider to be a very little effort mod to the rims.
If I was to purchase them again, I would ask HRE is adjust the rear offset slightly and I would also ask for a change in the front offsets on the 20x8.5. I believe the rim needs to come out a bit more, possibly 10mm (0.39 of an inch).
As I said, I’ve had these rims for a couple of years and for all I know HRE may have already changed the offset in the production process. If not, they may have a good reason why they are the way that they are. I’ve also noticed a number of other brands where the owners have had rubbing issues so it’s not just a HRE thing. Tyre choice in width and profile play a part, also how low you want to go with the car and I now have only a few mm clearance on the inside of the rim, it’s possible that reason alone could turn a manufacturer off. HRE must be doing something right though as I get a lot of comments on how good the rims look.
It would be impossible to cater for every need and that’s why these manufacturers offer ‘made to order’ rims and you can supply your own offset if you wish. To be fair, 9.5 is really the perfect size for this vehicle and that how Mercedes-Benz designed it.
