hello,

i changed my 185/55 R15 to 195/50 R15. 100euro cheaper. can i adjust the speedometer as it cheats even more now. 130 on meter, actual 120km

 

I don't think that's possible.

When I worked at vauxhall if we fitted irmscher upgraded alloys we had to reprogram the body control module to compensate for the difference in the possible rolling diameter

A vehicles speedo is usually over generous to compensate for tyre wear

I don't think it's possible, even with VCDS but look on the bright side.

You're less likely to be done for speeding
