Just got these for my X5 F15 in 315/35/20 Rear and 275/40/20 Front.
Right off the bat they are louder than the winter set i had on and they are much firmer than I had thought they'd be. To me it doesn't matter that much, however I note it as I know that many drivers prefer comfort.
This is an initial impression and ignoring the slightly higher road noise they are very responsive, car feels more planted and snappier.
Even tho they are quite firm, at speed, bumps are absorbed quite well.
Let's see how they get through the summer 2026 and I might update this toward autumn.
