Hey just looking for confirmation if someone would be so kind.

Looking to purchase set of 19 inch Amg style VI rims from a s63. Tire width is the same at 255 but offset show et43. Ive been told they are compatible but wanted to confirm will that offset work with awd w164 ML?

Thanks again

 

I think the ML63 offset is et46. What is the width of your current wheels and the width of the S63 wheels? If the widths were equal, compared to your current wheels with et56, you will likely have more space between your suspension and the inside of the new wheel with et43, and the outside wall of the tire/wheel will be 1.3 cm or .5" further out towards the fenders.

I would be concerned about the weight of the ML and whether the wheels from the S63 would be able to handle it over time.

 

I currently have 255 width on 19 inch wheels so they are both 10 inches. Load is fine just the way I understood the offset I thought with et43 I may need spacers as I thought they would be more recessed in the fender. That is image of them below.

 

The higher the offset, the deeper the wheel goes in the wheel well, the lower, the further it moves out towards the fender.

There is an image I found which should give you a. Idea about how it should work based on the offset. The wheel's hub mating surface which is mounted on the hub doesn't move relative o the wheel well, but the rest of the wheel will have to, based on the offset and wheel width.

I'm surprised that you have 255 tires on 10" wide wheels. Not saying it can't be done, but it stretches the tire and the bead seal may not be as robust and effective as on narrower wheels. Most tire shops wouldnt risk mounting 255s on 10" rims because of liability.

Back to your original question, if you have the same width on both, the offset difference is like adding a 13mm spacer to your et56 wheels.

 

Just to clarify the tire width is 10 inches, the rim alone is 8 or 8.5 inch. They are just stock setup on 19 inch 5 spoke mercedes rims currently.

 

Ah, I am sorry I misread the width of the wheel to be 10".
