VDC calibration with new tyres

seejay · 05-04-2016, 10:01 PM

I have had 2 x 350 and 2x 370zds. I have had a problem With the VDC when I change just the rear tyres.
If I just change the rear tyres the VDC will intervene on corners and I then have to replace the front tyres as well even though they are still serviceable .
it seems to be the difference between the rolling radius of the new tyres and the old upset the calibration.
Has any body else had this problem.

What size are your front tires and rear tires?

This happens with non-OEM tyre sizes that have diameters outside VDC tolerance - I use 245/40R18 and 275/30R18 which are within 4mm overall diameter and do not have a problem.

As Rusty says, what sized tyres are you using .........
