Im running 20" Volks on Tein S Techs and have never had a problem with it. Today I got new rear tires and an alignment and now Ive got the VDC and SLIP lights coming on, which I can only assume is due to the alignment. The tech used the standard specs for a 19" stock wheel- how different should my specs be with my 20s and S techs? Does anyone have the correct numbers? Thanks for the help.

 

Tires must be matched in friction coefficient across temperature range. Tires must be matched in loaded rolling circumference.

Static misalignment can change the shape of the loaded tire patch but the area stays nearly the same regardless.

Inflation psi changes the area of the tire patch.........weight on tire/ psi = area.

 

I have no clue what that means. I think you are alluding to me saying I only got new rears? The fronts were replaced about 5000 miles ago, the rears are the same brand and type as the fronts. Additionally, they are the same tires I used last time, BFG KDWs.

Here are my specs from the alignment. Yes, the camber is way off, but I dont have any way of correcting that, and it was off before, so I dont think that alone is the cause of the VDC problem.
