I am 100% with RC here - I've tried them just on a SUV and brought my car to the dealer saying I think something is wrong with the front differential - making these sounds - and they said the Pirelli's don't fit for this car making terrible noise and despite good alignment and correct pressure -  I have much more wear on the inside than outside..... - I never had that with Contis or Michelin's.... - I've decided actually now to only buy Michelin for my cars - must be psychological... indecision
