Continental ContiExtreme Contact DW 285/35 in rear will fit on 19X9 with 44mm offset? Tire rack has 9" listed as optional rim width for this size tire (interestingly, other brands of 285 require 9.5" rim). Went to 1010tires.com and plugged in numbers for 255/40 (19) fron and 285/35 (19) rear. Website says difference is 0.67% (below the magic 1% number I have seen quoted). Any thoughts on this setup? I have read that stock xdrive outside US comes with 245/40 (19) front and 275/35 (19) rear. Website has this as a 0.53% difference which I assume is negligible (0.14%)?
