Replaced OEM runflats which handled superbly but were so harsh and treadwear was only 15,000 miles, also very expensive to replace x2 as I picked up nails in the center of the tires which can't be repaired. New tires are much more quiet, much better ride quality but I did give up some of the handling and straight line steering responsiveness. I did have to go up a size in width but now the car looks even better. I'm no tire expert but overall, I'm
very happy with these tires.
