USR350

I have a 2006 MB R350 with 17“ stock wheels. I want to plus up 1 to 18” wheels but can’t find the right offset for 18” wheels. Does anyone know what it is? I'd like to move up to an 18" x 8" wheel and the 255/55/18" tire. Anyone know what companies would carry that size and offset wheel?

The 18x8 wheel has a +67 Offset.

Thank you. Sadly can't find a nice looking 18" wheel with a 67mm offset. The only wheel I can find look like the existing 17" stock wheels currently on the car.

you can have a bit of leeway with the offset.
There were AMG look wheel as options
.2010 AMG wheels were 8.5 wide with 60offset
2011 AMG wheel were 8.5 wide with 64 offset
2008-9 ML have 8 inch wide with 60 offset.
I have been running 17 inch wheels in winter from a 2008ML
7.5 wide with 56 offset.. Not a problem for 7 years.

Look at scrap yard for ML wheel from multiple years.

You could also go with Wheel Size: 8J x 19 ET 67. Tire Size: 255/50 R19.
