with an torsen quattro car, it's recommened to keep all tread wear absolutely even in order to keep rotation even at all four corners and avoid upsetting the torsen differential.

does the same rule apply to haldex quattros?

specifically, is it ok to mount two new tires in the front, and two tires with ~ 50% wear in the rear?

thanks.

With haldex they still need to be even all around. New in front and 50% worn in back is no good.

in rolling circumference between the front and rear tires. Worn tires (of the same brand and size) fall well within this spec, so replacing in pairs is OK!

Yup, not a problem with Torsen or Haldex cars in fact.
