You can change tire size with start. What are you wanting to change on the "gear"?

Tire size is in the ICM (Instrument Cluster) section. I don't have the star with me now, but I think it you just go in and adjust the control unit adaptations -> variant coding -> special equipment -> change the "tires" setting to your size.

This is from my US spec 2003 G500

"Chang gear" I meant as I installed portal axles with different gear ratio, maybe it is possible to define that?

I am not too sure, but I would check the settings in the transfer case

Drive -> VG Transfer Case -> Control Unit Adaptations -> Read codng and change if necessary

There will be settings for Tires & Axle ratio

Hi,
Okay, I was able to get to the part of define the tire size and the axle ratio. But was not able to define tire size 35" as the system is limited to some specific small sizes, had no option to define 35" or 315/325 size
Any idea?
