Side-drenched tyres

Hello dear community, I have a problem with my E92 from 2007. My question would be whether these tyres can still be driven without problems (legally). As according to… § 36 StVZO in the wording “Air tyres on motor vehicles and trailers must be equipped with profile grooves or cut-in on the whole circumference and width of the tread. The main profile must have a profile depth of at least 1.6 mm on the whole circumference; the main profile shall be the wide profile grooves in the middle The wheel crash and air pressure has been adjusted. But 110€ for a new or 2 for 220€, for the axle is a bit too bad for me. Since 3-4mm profile is still present in the middle. I am happy about every answer. Tires: Hankook Ventus V12 Evo 2 235/35 ZR19 91Y Ps: The last picture is of one of the unexcited tires.
