Will having different diameter wheels trip VDC?

[Lachlan S]

Hey everyone, was just wondering if I wanted to take my car to a skid/track day and want to save my good rear tires on my nice wheels, would it be possible to keep my normal 19/35/255 tires up front and run the stock 18/40-45/245 tires on the rear?

 

Will this trip VDC? Is there a workaround?

 

or would it just be better to swap all 4 to stock for skid day?

Assuming your case is 2wd there should be no problems due to the different wheel diameters.

VDC should work against doing skids. If your car allows you to turn it off you should do that while attempting skids.

If you're concerned about your nice tires I'd swap all four, the front tires still take a hiding on the track

It will for a bit, but it will adjust.  I had 225/45/18 tyres on the front of mine and 245/45 tyres on the rear, I swapped them front to rear to test something, the first few hundred meters VDC when psycho, but sorted itself out.  Same thing happened when I swapped them back.

Also had this issue when replacing tyres and fitting 245/45 tyres all round.

VDC seems to have some way to determine this different wheel speed is normal after a short time.
