I am currently running mismatch black wall on purpose. I essentially went with a quiet street tire on the front and an aggressive AT tire on the rear. The noise difference is amazing.

 

Our friends' Ex was sideswiped last August, and in addition to right side doors/fender/quarter, it needed a new wheel/tire for the rear. They too had the older Michelin LTX M/S with white letters out. Insurance wouldn't pay for a new set of tires (and the ones they have aren't that old/used), so they just had the tire store turn the other three around to put white letters in. So now the new M/S2 one is different, but it's much harder to tell.

 

I saw your wife at the grocery store yesterday sporting the mis-matched tires and I didn't even wave. We have been friends since high school and I was thoroughly disgusted and disappointed as I thought she had married into a more classy situation. Rectifying the tire situation might restore our friendship but frankly, the damage has been done.

 

Too bad the Ex hasn't tried out the new tires yet, so you must have been mistaken her for another woman whio married an unclassy person. I need to save up to buy a tank of diesel.
